Alison DiLaurentis

Alison DiLaurentis is a character in the series and had been the best friend of Hanna, Aria, Spencer, and Emily before disappearing the night of August 31, 2009. She had been the Queen Bee of Rosewood High School, before mysteriously disappearing one night. One year after her disappearance, her body is found buried in the backyard of Maya St. Germain's house, which used to be Alison's house.

Appearance & Personality
Alison DiLaurentis was well-known for her beautifully long blonde hair, heart-shaped face, and ocean-blue eyes. Although Alison appeared to be innocently kind and loving, she was a very flirtatious and playful young woman who possessed a wicked streak of deceit and manipulation within her.

Season 1 Flashbacks
The show begins with footage of the night Alison DiLaurentis disappeared. Alison, Aria Montgomery, Spencer Hastings, Hanna Marin and Emily Fields were having a sleeping party in Spencer's barn. Alison had scared them by sneaking up on the other girls in the barn's doorway. They had laughed and joked at the time. Later the girls had drifted asleep, and Aria had woken up, followed by Hanna and Emily, to find Ali and Spencer missing. Spencer had returned to let the other girls know that Ali was missing and that she had gone looking for after hearing a scream.

Also in "Pilot," Aria has a flashback to the same summer when her and Alison had meanly ditched then-nerd Mona only to find her father, Byron, kissing another woman inside his car.

Spencer flashbacks to a moment around the same time, when Melissa was dating then-boyfriend Ian Thomas. She had been standing with Alison and Hanna in her kitchen, when Ian and Melissa had walked in. Suddenly, Alison announced that Spencer had something to reveal, but Spencer denied anything, annoyed and angry by her so-called friend's blunt betrayal. Outside, out of earshot, Ali had threatened to expose Spencer's secret in front of her sister, namely the fact that she had once kissed her sister's boyfriend Ian. Spencer had countered with a threat to expose Ali's involvement in "The Jenna Thing."

In "The Jenna Thing," it is revealed that one night when the girls were trying on clothes, Alison spotted someone spying on them, who she claimed was absolutely Toby Cavanaugh. Immediately after this, Alison hatched a plan to drop a stink bomb in his garage. Emily and Aria tried to back out, while Hanna and Spencer also shared their reservations, but Ali was adamant that someone spying on them must be taught a lesson. Alison had then ordered Spencer to pass the match and ignited the firecracker, opening the door of the garage, and dropping it inside. But the prank went terribly wrong as the garage caught on fire, and Alison saw too late that someone - Jenna Marshall - was inside. As a result, Jenna was permanently blinded from the accident, and Alison made sure that Toby falsely took the blame for it. Alison had blackmailed him with something that she knew, but what exactly had not been clear to Spencer.

In "The Jenna Thing," while Emily is sitting by herself in a restaurant, she looks down at her bracelet and flashbacks to the aftermath of "The Jenna Thing," when Alison had bought the other Pretty Little Liars friendship bracelets with their names on them. Alison had given the girls the bracelets in the same restaurant in which Emily is now sitting. At the time, she had even suggestively asked Emily to tie hers for her.

In "To Kill a Mocking Girl," Hanna is being interrogated by Detective Wilden, who suspects Hanna of having tried to kill Alison out of jealousy. She assures him that no body tried to compete with Alison, that it was pointless, and this in turn prompts her memory of the time in her chubby days when she asked Sean out to a party. She had asked him in quavering voice, and Alison had stepping in, pointing out that everyone was going. She had made eyes at him, and he had accepted, perhaps because he really found Hanna charming and perhaps also because Alison had been hard to resist.

At Noel's cabin party, Spencer suddenly recalls the night of "The Jenna Thing," when the girls had to deal with the aftermath. Alison had been standing in front of the Cavanaugh house, blackmailing Toby with something to get him to take the hit for the fire in the garage. Spencer had walked over to listen, and Alison had angrily pushed her back, mad that she violated her order to stay away. She had followed Spencer to the rest of the girls and tells her friends that she would have not set off the bomb in the garage if she knew someone was in there, even though it seems that she did see Toby and Jenna in there. Then, Hanna had expressed her desire to come clean to the police and explain it was an accident, but Alison had railed on Hanna, basically calling her a fat loser until Aria scolded her, forcing her to apologize. But Alison had made sure to get her way and to make the girls flee the scene, letting Toby take the fall. Spencer remembers seeing Toby before he was taken away in the cop car to the police station.

It was revealed that Alison was threatening Toby to take responsibility, but he had told her that he will make sure she takes responsibility. In turn, she had threatened that if he tells, she would tell everyone Jenna and Toby had a relationship.

In "Can You Hear Me Now?" Aria watches her mother preparing dinner in the kitchen. She suddenly recalls the incident she witnessed, involving her father and Meredith kissing in his car. This time, she additionally remembers how Alison had tried to convince her to tell her mother what she saw. When Byron had tried to call Aria, Alison had warned her not to pick up, correctly suspecting that he would try to talk Aria out of revealing what she saw. Alison had warned Aria that she could risk losing both parents if she didn't tell.

In "Please, Do Talk About Me When I'm Gone," preparations for Alison's memorial sparks memories of a summer day that the girls had spent lounging by the shore of the lake. Ironically, the girls had spoken about immortality and the fantasy of living in this moment forever. Alison had said that one could attain that only by dying young and leaving behind a beautiful corpse. Getting into it, Alison had romanticized how fabulous it would be to die in a mysterious way.

In a flashback of Spencer's, she recalls who else was at the beach that day. Jenna had come to start a barbecue, wearing her now familiar shades before taking them off. Alison had expressed her annoyance, and Emily had commented on Toby's conspicuous absence. When Alison had responded by mocking him in conversation, Spencer had rolled her eyes and pointed out how typical it was of Alison to taunt others. But, she softened when the girls all agreed that this day was perfect and then shared their dream that they would be friends until they grow old.

After Hanna makes a comment to Aria about how she used to crush hard on Noel, she flashbacks again to that day and remembers how she and Alison had spotted Noel with a girl named "Prudence." Alison had torn into her too, suggesting that she was anything but chaste with Noel and provocatively suggested that she had gotten a boob job. Aria had ogled at Noel applying sun block on her enviously. As if reading her mind, Alison asked if she would "also" do something like that to get Noel's attention. She then teased Aria for falling for brainy guys. She also called Noel immature and simultaneously perfect for Aria, flustering her.

Later, Hanna remembers who else Alison had picked on that day. When Lucas had run in front of them to pick up his toy motor boat, she had incessantly made offensive comments to him. Finally, Hanna had exclaimed "hey" as if to stand up to Alison and stop her from teasing him, but she recoiled and sat silent. Alison then turned on her, warning her to never let a moment pass, as Lucas trudged away.

And, Emily remembers more of Alison's snide remarks that day. As she puts on Maya's gift scarf before the mirror, she recalls how Alison had commented on the pair of Noel and Prudence heading to where assumed was The Kissing Rock. She matter of factly informed Emily that people had gone there to kiss for hundreds of years. She then looked Emily daringly in the eyes and asked her who she would like to take to The Kissing Rock. Emily had just smiled shyly while staring back.

In "The Perfect Storm," Emily is directed by "A" to the school library's copy of "Great Expectations," the same book Alison had been reading one day alone in the library. Emily had joined her on the floor, and Alison had stroked Emily's hair affectionately. Emily revealed her dream that Jenna could see again, and Alison had said something to the effect of "that's why I love you, Emily." She then read her the passage of Pip's account of his ardent love for Stella: he loved her against reason and despite the fact that she basically played hard to get and gave him little hope for a future, other than her teasing. Quite fittingly, Emily had then leaned in to kiss Alison, expressing her own love of the same nature. Alison had actually smiled in return.

While reading the letter that she had written for Alison, Emily then remembers when she had been in the locker room with Alison alone. Alison was changing; she removed her towel to reveal her topless half and before putting on her bra, had made conversation about how she bought it in a French catalog, forcing Emily's already attentive eyes to stare. She had asked Emily to hook it, and after doing so, Emily had kissed her neck. Alison immediately turned on her, (feigning shock) and cruely let Emily know that their kiss meant nothing more to her than target practice for "the real thing". Abashed, Emily had turned, poised to leave, but Alison wouldn't let her escape the moment: reminding Emily that she was supposed to be giving her a ride home. Defeated and humiliated Emily nevertheless remained, showcasing Alison's control over her friends.

In "Keep Your Friends Close," Spencer tries to convince Melissa to reunite with Ian. Afterwards, she flashbacks to the previous summer when she had been practicing her field hockey swing on the front lawn. Ian had walked by, and, under the pretense of correcting her technique, put his arms around her waist and leaned in to kiss her neck. Surprised, Spencer had turned around to face him, and this too ended in a series of mouth kisses. Then, Alison had called out from where she was standing a few meters away; she had let Spencer know that she saw her kissing her sister's boyfriend. She had called it disgusting and basically called Spencer a skank to boot. (Evidently, she had been jealous.)

In "Salt Meets Wound," Hanna is in her wheel chair at the party Mona has thrown for her, when Noel walks in. Just the sight of Noel prompts Hanna to have a flashback about him at a different party, when Alison had manipulated a girl to dump Noel, who gave him a nasty look in return. She had claimed that all of them had done it, when it is obvious that the girls had been oblivious to how Alison had even managed to break them up in the first place. She claims that they had done it for Aria, so she could have him instead.

Later, Spencer sees a "Hilton Head" tag for a country club on Ian's luggage and has a flashback to Alison returning from an alleged weekend visit with her grandma in Georgia and with the same tag on her luggage from South Carolina. When Spencer tried to question her about the club's location being in South Carolina and Alison's grandmother being in Georgia, Alison had deflected the questions, derisively. This had been on the day that Alison disappeared, and she had been eager to share her vacation stories with the other Liars.

In "Know Your Frenemies," when Hanna is forced to eat a half dozen cupcakes by "A" she flashbacks to one day when she had eaten an entire pie in her kitchen at home. Alison had come in, and Hanna quickly tried to clear the evidence by throwing it in the garbage, however, Alison saw it anyway. Hanna had broken down into tears, and Alison had comforted her friend, hugging her and murmuring, "I understand". She then wiped away Hanna's tears and told her that she didn't have to feel that way, and she could show her how to get rid of it. Presumably, Alison had shown Hanna how to purge the calories she had just binged.

In "If At First You Don't Succeed, Lie, Lie Again," Spencer guiltily recalls how the night she disappeared, Alison had pressured Spencer to tell her sister about Ian. (This was hypocritical considering the fact that she was secretly dating Ian, and Alison probably did it in order to make Spencer look bad while getting Ian to herself.) Spencer had refused, but Alison warned that Melissa would find out the next day, whether Spencer told her or not. Alison had arrogantly claimed that Spencer and the other Liars were her puppets. Spencer had furiously countered that she was sick of her games; she would tell Melissa, but Alison was dead to her already. Alison had appeared distraught, then had left angrily, and after a moment's pause, Spencer had marched outside after her.

In "The Badass Seed," the girls flashback to a college party Alison had taken them to, probably in an effort to spy on Ian. Ian had been flirting with a particular tipsy girl and had gone off with her to one of the rooms upstairs. Later, that girl had taken a nasty tumble down the stairs. They had all exchanged looks after her fall, and in hindsight, the girls are left to question whether Ian or Ali had pushed that girl. Later, the Liars had stood on the lawn, discussing the incident, as a stretcher passed by. When Alison had shown up, she had seemed either oblivious to the girl's accident or indifferent. At the same time, the girls were afraid of being caught underage at a drinking party, which was very likely with the police swarming about. Alison had taken charge of the situation, brazenly asking a police officer for a ride home in his cop car, claiming to be tipsy to get behind the wheel, when really she had not wanted to take the bus and was too young to even drive. She had wisely explained, "the bolder the move, the less anyone questions it." The girls had gotten in the car, before exchanging looks with Ian on the porch.

In "Monsters in the End," Emily makes a discovery after the Rosewood Founder's Festival. Emily reverts back to the last time she saw Alison; she had visited Emily in her bedroom to give her a snow globe as a souvenir gift from her vacation. As she had not bought any gifts for the others, she asked Emily to keep it a secret from them. She had mysteriously alluded to the fact that it was more special than one would realize at first. This flashback prompts Emily to examine the toy, and at the bottom, she finds a key with numbers printed on it. Thanks to the clue, Emily, Aria and Hanna track down the matching location and uncover a flashdrive contained in a lunch box, stored in a garage that Alison had planted! The flashdrive contains secret videos, mostly of the girls in intimate moments; Alison had somehow known that they were being spied on while she was alive. There is footage of Jenna on these videos as well, meaning that the Liars hadn't been the only girls to be spied on.

In "For Whom the Bell Tolls," the girls corner Jenna to confront her about the incriminating video they found of her and Toby. Jenna discloses that Ali had visited her in the hospital on the day that she disappeared. She had played the video footage of Jenna seducing her brother, and Jenna fumingly asked Alison were she got it. Alison had replied that the guy she likes likes to make videos, perhaps vaguely referring to Ian. She had blackmailed Jenna that if she ever told anyone about what they did, she would release the videos. Jenna had only sat exasperated before Ali took the computer and moved to leave. Alison had then turned to warn Jenna that if she ever returned to Rosewood, she would bury her. The Liars believe Jenna's account, given how it explains her seemingly strange speech at Alison's memorial dedication.

Season 2 Flashbacks
In "The Goodbye Look," after Jason returns to his former home in Rosewood, Spencer drops by to give him cookies in hopes of finding out information from him. It turns out Jason wants information from her, but when she is vague about whether Ian confessed to killing Alison, he returns inside. While still standing on the stoop, Spencer flashbacks to one summer when Ali and the Pretty Little Liars' were lounging in the DiLaurentis' front yard. Jason had stormed out of the house, accusing Alison of messing with his stuff. She had retorted back sharply, mocking him and his friends for being stoners; the Pretty Little Liars' had snorted. When Jason went back into the house, they had questioned Alison whether she had stolen what he claimed she had. She had admitted it gleefully. When Emily had asked her whether she was worried that Jason would rip apart her room in search of his things, she mischievously replied that he would never find what she hid. Just then, a smashing sound was heard from inside the house, though Alison had seemed unfaded. Spencer snaps back to reality when Jason's porch light switches off.

In "My Name Is Trouble," Spencer is troubled sleeping alone in her house. She looks out her window and sees Jason inside the room opposite hers, newspapering the windows to conceal everything inside. It prompts her to flashback to a time when Jason was having a party with his friends, and a distraught Alison had come to Spencer's house seeking refuge from the drunk boys at the party. She had been in a tearful state, but had lashed out when the girls tried to show her compassion and support, insulting them and turning impersonal. Emily had been over at the time as well, and the two girls wondered what had happened to Alison that upset her so much, other than party boys stumbling into her bedroom for all sorts of reasons. Alison had made up some story about her grandmother not being well.

In "Never Letting Go," the Liars lunch with Ali's mother Jessica, as per her request. There, she presents the girls with presents, four high fashion outfits. However, the girls are uneasy, as they remember Alison trying them on and having picked them out. They had all been standing in Alison's room, watching her try on the couture. She had compared the dresses to her friends: unique and hers.

In "Surface Tension," after Toby shares news of the hockey stick discovery with Spencer, she flashbacks to when Alison had asked Spencer to show her how to play field hockey. Spencer had been happy to do with her old hockey stick with the Rosewood Field Hockey team colors on it - blue and white. Aria had been suspicious at the time, knowing that Alison wasn't the biggest field hockey fan. She had guessed that it was for a guy, which was probably correct, knowing that Ian was the field hockey coach, and Alison was secretly dating him. At the time, Alison had just smiled while Spencer claimed that guys don't play field hockey, and Alison said that she wasn't "yet" into field hockey.

Spencer then calls Aria to fill her in on the details of the find. Spencer immediately suspects Jason of having hurt Alison and trying to cover it up by burying it and later building a fence to the side of the property line, where the evidence is buried. Making Jason look even more incriminating is Aria's flashback of Jason the day that Spencer had been showing Ali how to hold the hockey stick. He had come looking for her on their mother's orders, unhappy to have to find Ali. When he had caught sight of the stick, he had grabbed it from her and then threatened to hit her. Spencer had let out a warning cry. When Jason had turned around, Ali had tried to whack her brother with the stick, but Jason had moved quickly, and mockingly warned Ali that she wouldn't get a second chance.

In "I Must Confess," Spencer flashbacks to the summer before Alison had disappeared. The girls had been standing in Hanna's kitchen, and Hanna's grandmother Regina had been over as well. She had been talking about her two sons, Tom and Patrick, and Alison had suddenly asked what it would take to have one of them removed from her will. Regina had been taken aback by the question, but Alison had pressed on with: if one of her sons sold an expensive family heirloom to buy drugs, would that constitute dismissal from the family tree? Regina had gone along with it. In retrospect, Spencer believes Alison to have been referring to her own family situation and thinks that Alison had gone to Georgia in order to try and get Jason back into his grandmother's will. She assumes that Jason must have been cut from his grandmother's will for doing such a thing, while Alison, the beloved granddaughter, remained intact.

In the prequel episode, "The First Secret," taking place Halloween 2008 before Alison disappeared, Alison is seen as the ringleader of The Pretty Little Liars.

One day, while Hanna had been babysitting a young boy, Alison had been narrating a scary story about two blonde twins. In the story, after the twins get into a fight over a doll, one of them gets mad and stabs the other in the heart with a knife on Halloween. At that point, Hanna had thought that Alison should stop telling the terrifying tale, but the child was riveted. So, Alison had continued on about how the murderess little girl went to the asylum—“until yesterday!” and had vowed to kill every kid who goes trick-or-treating.

Later on, the five Liars had been walking together. Alison had been bossy with regards to Hanna's costume decision and had taken a jab at Hanna's weight. When Spencer had gone on about her bid for class presidency, Alison had mocked her and teased her big vocabulary. Just then, Noel had driven up in a convertible with his jock friends to greet the Liars and especially Alison. He had invited all the girls to his party on Alison's account. After the girls gushed in excitement, Alison had mocked them for being so excited that to attend the party.

They had continued walking past a run-down abandoned house. A figure had been seen in one of the upstairs windows. When Emily brought it up, Aria commented that she got a bad feeling from this place, feeling as if something bad had happened there. Spencer attributed the movement to typical Rosewood kid activity on Halloween, and Alison had been equally nonchalant. After they walked away, someone opened the door, and a van is seen marked "Radley Sanitarium." Does this mean Alison's scary story wasn't an invention?

Later at the local costume shop, Noel had startled Alison by grabbing her from behind and covering her mouth while wearing a scary mask. Alison had been ruffled, but not upset. She had then spotted the new girl in Rosewood buying her costume - a "Lady G." costume. She had tried to intimidate her to buy a new one, declaring that that is her own costume choice for the year. The new girl had noncommittally agreed to think about changing her decision, but turned her attention away from Alison. Before walking away, Alison had offered her name, to which the girl replies that she already knows it, and her own name is Jenna. They smiled pleasantly, if not fakely, at each other, and Alison had strolled away with her basket on her arm. She had then got an anonymous text reading “I’m watching you” from a blocked number. Unnerved, she had scanned the store for the perpetrator, but discovered nothing. She had then turned to be surprised once more by another scary mask-clad person, only this one had on a burlap outfit, and Alison was not tolerant of the sneak-up. She barked "freak" before walking away, without knowing who the person behind the mask was.

In Spencer’s living room later that day, Alison had flirted with Melissa’s boyfriend Ian, who was holding a video camera in his hand. He had filmed Alison talking about her grandmother in Georgia who was a sweater model. After a few more lines about her own photogenicity, she turned the camera on Ian and filmed him talking himself up. Alison had immediately set the camera down when Melissa and Spencer descended the stairs. Alison had made a comment about Melissa's support of Spencer in the presidential election, though her tone had sounded particularly ironic.

That night, Alison had called Hanna to ask if it had been she who texted her in the costume shop and whether she had been in the costume shop in the first place. When Hanna had replied in the negative, Alison had not bothered to offer an explanation and hung up.

The next day at school, Alison had joined the other Pretty Little Liars at their table in the cafeteria, and a nerdy Mona had tried to do the same. Alison had vended her off, leaving her to nurse her wounds at Lucas' table. When Alison heard that Ben was telling everyone that he and Emily had sex; Ali had seemed impressed.

Later, in a familiar scene, Aria and Alison had gone out for frozen yogurt. While they were walking, Mona had seen them and called out to join them. Aria had looked inclined to stop, but Alison had propelled Aria forward in attempt to lose Mona. They had run until they turn a corner past some bushes, then stopped in their tracks when they saw Byron and Meredith making out in his car. Byron had been all smiles until he spotted his daughter and her crestfallen face.

Next, Alison had been sitting on her bed, writing in a notebook, when Jason entered without knocking. She immediately shut her notebook sarcastically asked if he'd ever heard of knocking. He told her if she wanted to keep him out, she should put a lock on her door, prompting her to ask what he and his friends do behind his. He says he will tell her for $20. When she forks it over, he says that they are making a movie, but if he told her what kind, he'd have to kill her. He then tosses her a package and says he found it on the porch. Before opening it, she tells Jason to leave. Inside, was a burlap doll with a red heart stitched on and a note pinned to it's head reading, "It's my turn to torture you". Ali had read the note aloud, and looking around her uncertainly. She had then opened the radiator grill and pulled out a box of her hidden belongings. She pulled of the head of her porcelain doll and slipped the note inside, before recapping it and putting it back in the box, which she hid back where it originally was. Meanwhile, someone had been spying on their house with binoculars and zooming in on their mailbox.

Spencer had been in her living room making something on her sewing machine when Alison had come knocking later that day. Alison had informed Spencer that a friend on the election committee had let her know that Spencer might not win the election. Alison had tried not to be too harsh, telling her that it would be close. Spencer was crestfallen, afraid of her parents' reaction. Alison had used the opportunity to bash Melissa for purposely trying to outshine Spencer in her parents' eyes. After all, Melissa had made some of the phone calls in inviting people to Spencer's congratulatory party. Her motive in creating the sibling rivalry was not totally clear. She had toyed with the needles and stabbed one deep into the holder near the sewing machine as she talked. Ali had offered to fix the election for her, and Spencer had accepted.

The next day, Emily had walked with Alison. Alison was discussing the possibility of Emily going on the pill, but she confessed to Ali that the rumors weren't true, and she wouldn't be needing contraception yet. She had asked Alison not to tell anyone, and Alison had been perplexed until she discovered Emily's secret later that night...

Later in the school hallways, Alison had suggestively let Spencer know that it had been taken care of. When the other liars questioned her comment, she had lied that she helped Spencer with her speech. Alison had changed the subject by piteously asking Aria how her mother is. Aria had shot daggers at Alison and was about to respond when Lucas had bumped into Alison, dumping his drink on her. Angry, Alison had rejected Lucas' apologies, mercilessly calling him "Hermie" and publicly suggesting that he was really a hermaphrodite. When Alison walked away, Lucas had growled that she would get what's coming to her, and Mona had nodded uncomfortably in silent agreement. Next, there had been an announcement over the school loudspeaker that the election results were in, and Spencer Hastings was the winner. Smiling, but insecure, Spencer had accepted people's congratulations, and Alison had winked knowingly at her.

That night, the girls had gotten dressed in Spencer’s bedroom. True to her promise to Jenna, Alison had been dressed as Lady GaGa. Aria had walked in and announced that she didn’t feel like going. The girls had accepted Aria's decision, sans explanation, but Alison didn't. Suddenly, someone dressed in a burlap outfit with a doll mask had been outside the window. Spencer had noticed him/her, and the girls had all squealed with worry. The doorbell had rung at that moment, presumably for a pizza delivery, but Spencer had insisted on going downstairs with company. When Alison and Aria were left alone, Alison had criticizes Aria for being such a downer and not going to the party after she had supposedly worked so hard to score her an invitation. In response, Aria had shown Alison a meek defense.

At the Halloween party, Noel had approached the Liars. After spotting Jenna, he had gone straight to her, who was also dressed as a sexy Lady GaGa.

When a Lady GaGa song had started playing, Mona, dressed in a cat-suit, approached Alison with a hello. Alison had asked if she knows her, to which Mona had mysteriously responded no, but Alison will. Ali had then approached Jenna. She had offered to befriend her, thereby making Jenna's popularity in Rosewood a sure thing. However, Jenna had turned her down, saying that she likes to pick her own friends. Alison had been rebuffed.

Outside on the porch, Ali had sulked and jealously called Jenna a slut. She had then handed Spencer the ballots of incriminating evidence. Spencer had burned them in a nearby fireplace without looking inside, though Ali had cryptically told her that she would be surprised to know who her friends weren't and had suggestively glanced Aria's and Hanna's way.

Then, Emily had been seen slow-dancing with Ben on the dance floor. Jenna had been seductively dancing nearby, and Emily had ogled at her moves and curves. Alison, turning her eyes from one to the other, had approached Emily, and alluded to her hidden sexual orientation. Emily looked frightened, and Alison had let her know that her secret was safe with her.

Some time later, the girls had noticed Ali gone. Just then, they had all received the same text reading, “I’m in trouble, come alone” from Ali, directing them to the scary house's address. So, they had all hurried over there.

They had found Ali in a locked room. Seemingly terrified, she had recounted that someone grabbed her and brought her there threatening to kill her with a knife. Nobody could get a signal to dial 911 from their cell phones, so Ali had gone out alone. Then she had screamed, but the door had been bolted so that they couldn't open it. Through the keyhole they could see a big fight with her and costumed guy with a knife. Ali had kneed him and run off. Meanwhile, the Liars had managed to escape through a conveniently open window. They had gone back into the house, where Ali had been swaying in a rocking chair, brandishing a red stained knife and looking completely insane, but she had claimed it was all a hoax: Noel had been the zombie, the blood had been ketchup (which she had meanly offered to teary-eyed Hanna), and they had “passed the test." Spencer had been the only who could voice her betrayed feelings at Alison's dumb joke, but Alison had unabashedly countered that she now knew that she could count on them as her friends when she needed them. They had all look really annoyed and betrayed by Alison's crying wolf, but had been silent.

Back at the Halloween party, Alison had approached Ian and flirtingly struck up a conversation with him. But, Melissa had cut her off by spinning Ian around and planting a kiss on his lips. Disgruntled, Ali had walked back to her friends.

Noel had then approached Ali to apologize, but she told him it was perfect—before realizing that he had been apologizing because he hadn't been able to participate in the prank, not because he had been too rough with her; he had been stuck at the party since his brother took the car. Alison had now been taken aback. Who was it then? Suddenly, a guy in an identical costume had brushed past Alison and mutters "bitch." Alison had looked offended, and the guy took off his mask as he walked away, revealing that it was Lucas.

Then, Alison had received a text: “Dying to know who I am? You’ll find out. –A.” When Spencer questioned the text, Alison had called it "a secret."

Appearances in Hallucinations
After having a flashback in "Pilot" of Alison, Spencer looks out the window and sees in the window of Alison's house across from hers, a wavy blonde figure moving about inside. Spencer gasps, "Alison."

In "Moments Later," Hanna envisions Alison donned in a candy striper outfit visiting her in her hospital room. She smiles at Hanna and sits beside her. Weak, Hanna tries to ask her what happened that fateful night, but all Alison will say is that the four of them combined already know the truth. Additionally, she tells Hanna that bitchy "A " annoys her, and the girls must take care of her. She reveals that it is dangerous for her to have come, but she did it when she saw Hanna in trouble. When she leaves, a berry colored lipstick stain - the same shade that Alison is wearing - is seen on the rim of a Styrofoam cup near Hanna's bed.

In "Blind Dates," Hanna tells Dr. Sullivan her true feelings about Alison, in hopes of letting go. Her role playing makes it seem that Alison is really there, taunting Hanna for her feelings. Hanna calls Alison the best friend she ever had, but also her worst enemy. Alison is condescending, but Hanna doesn't allow the mental torture to continue, not caring whether Alison approves of her anymore. In her head, Alison is calling Hanna's friends things that Alison has given her and derides her that Hanna can't live without her. But, mentally, Hanna lets the ghost know that she is over her, that she won't let her into her life anymore, and that she is ready to move on. After the talk with Dr. Sullivan, her office is trashed, and "Nosey bitches die" is written on a wall in red paint.

In "Over My Dead Body," Emily, in a gas related brink of death, hallucinates that she sees Alison. Alison tells her that she liked her the most and was her favorite. She also questions if she really wants to be free of "A", and also questions whether she wants to stay in the position she is in or join her on the other side. Emily then asks if she knows who "A" is. Alison responds that of course she knows. After Emily asks her to tell her, she states she can't because "Two can only keep a secret if one of them is dead." She kisses her gently and Emily awoken from her unconscious state by the liars. She is so distraught that she believes what she hallucinated actually occurred.

In "If These Dolls Could Talk," Spencer wakes up in the middle of the night in her living room to find Alison rummaging through the box Jason gave her. Alison asks Spencer not to scream, claiming she only needs something from the bag. Alison asks Spencer if she is mad at her for never telling her about Jason being Spencer's brother too. Alison says that by sharing a brother, it practically makes them sisters and that Spencer deserves a more decent sister. If she had told Spencer the truth about Jason, it would have changed everything, and Alison didn't want that. Alison sees a bottle of pain killers on the living room table, and asks to take a couple "for the road."

Spencer informs Alison that Aria met with Duncan and he told her that he flew Alison back from Hilton Head the day she dissapeared. Alison says Duncan "talks too much," but states she is glad that the girls haven't given up. She also says that it is now helpful the girls have the bag. She gives her a hint by telling her to look at the big picture instead of scrutinizing the individual pieces. Spencer asks what is in the bag that is so important, but Ali says she can't say. She states she misses Spencer and that everything the girls are dealing with is "some seriously messed up stuff." Ali informs Spencer, "here's the good news, you're getting warmer."

Suddenly, Spencer and Alison hear a noise coming from upstairs, so Spencer stuffs the bag underneath the couch and falls back asleep. She wakes up the next morning to Melissa complaining that the room is freezing and discovers that the living room door is opened wide. Spencer alsoo sees the bottle of pain killers on the living room table uncapped. Spencer is left contemplating whether what happened with Ali was actually a dream or if she was really in her house.

Posthumous Video Footage
Before disappearing, Alison had met with Ian at "The Kissing Rock," where they had made a makeout-tape. In the footage shown to the girls by Agent Cooper in "Know Your Frenemies," Alison teases Ian, "I know you want to kiss me." Ian replies, "Come closer." A struggle appears to occur, and the camera falls to the ground, losing focus on the other two. Then, Alison's hand falls into view of the camera; her hand grabs onto some dirt and leaves, before going limp.

Then, in "The Devil You Know," it's discovered that a few seconds after Ali's hand had gone limp, she had moved it again, gotten up, and thanked Ian for meeting her there (meaning that Ian had not killed her in that moment).

Ian Thomas

 * Started: Before "Pilot"
 * Ended: Before "Pilot"
 * Reason: Her death.

In "Surface Tension," Alison asks Spencer to teach her how to play field hockey, which happens to be the sport Ian is coaching. When Aria says that maybe Alison is interested in playing field hockey because of a guy who also plays, Spencer says that only girls play field hockey, not even realizing that Ian was the coach at the time.

Peers
Alison is the ring-leader of her group of friends, which consists of Hanna, Aria, Spencer and Emily. Alison had disliked Mona, who was dorky at the time and constantly made fun of. When Aria thought about being nice to her and waiting for her, Alison convinces her not to. Alison treats Hanna like her lackey, and Emily is hinted to be more than a friend. She also made fun of Lucas a lot and called him a hermaphrodite, or "Hermie," which led to Lucas smashing up her memorial. She as well did not like Jenna and refers to her as "Jenna the Jerk" and states she finds her creepy.

Aria
Alison has a more neutral relationship with Aria than the other three girls. She seems to have the loosest connection to Alison compared to the other three girls. They seem to get along and have a casual friendship.They don't get into many arguments, nor does Alison treat Aria like a lackey. However, Aria does follow Alison's suggestions most of the time. Alison mostly lets Aria do her own thing and does not often get involved in her personal life, other than the time when she suggest that Aria tell her mother about her father's secret affair. Of all the girls, Aria seems to be the most like Alison. They are both naturally independent and obsessed with their own sophistication. They are both also very romantic.

Emily
It is seem multiple times through out the series that Alison was not such a great friend to the liars. They had more of a Frenemy relationship. Instead of the usual supportiveness the other girls had with each other, she either left her friends annoyed with her or feeling bad about themselves. In "The Perfect Storm," we learn Ali and Emily had a relationship that was more than a friendship. She wrote Ali a love note and loved her more than a friend. Alison was leading Emily on though and had no real feelings for her more than friendship. However, in "Monsters in the End," she chose to give Emily the snow globe with the hidden key. Alison tells her to keep it safe because it's "a lot more valuable than it looks." This might mean that Alison trusts Emily more than the other girls.When Emily was brink of death In "Over My Dead Body", she hallucinates that she sees Alison. Alison tells her that she liked her the most and was her favorite. She also questions if she really wants to be free of "A", and also questions whether she wants to stay in the position she is in or join her on the other side. Emily then asks if she knows who "A" is. Alison responds that of course she knows. After Emily asks her to tell her, she states she can't because "Two can only keep a secret if one of them is dead." She kisses her gently and Emily wakes believing Ali saved her and it was real.

Hanna
Alison bore Hanna the name "Hefty Hanna" mocking her weight, Despite being the sweetest of the bunch, Hanna was often cruelly mocked and teased by Alison. This is seen in "Know Your Frenemies" as well as in "Never Letting Go" and other episodes. In "Know Your Frenemies" we also find that Alison even convinces Hanna to throw up to lose weight. She also convinces Hanna not to eat in "Pilot" with the excuse she is being a friend. She is very mean to her during "To Kill a Mocking Girl" calls her a wannabe and other rude words leaving Hanna in tears. She doesn't stop until Aria expresses her outcry. She usually leaves Emily and Hanna feeling bad about themselves. Hanna also has the most hallucinations about Ali such as in the hospital and with her therapist.

Spencer
Her relationship with Spencer is very different. She usually leaves Spencer annoyed with her and Ali distressed because Spencer is the only one of the four girls who could ever stand up to Ali, which fact first comes apparent in "Pilot." There, she threatens to tell Melissa about Spencer's kissing Ian or else she will. Spencer yells at her that if she should so say one word to her, she'll tell everyone the truth about "The Jenna Thing." Also in "If At First You Don't Succeed, Lie, Lie Again" she is again seen pressuring Spencer to tell her sister about Ian. (This is hypocritical considering the fact that she was secretly dating Ian, and Alison probably did it in order to make Spencer look bad while getting Ian to herself.) Spencer tells Alison that she is sick of her games, and Alison is dead to her already. Alison appears distraught, then Alison leaves angrily, and Spencer follows her.

Jason
She did not have such a great relationship with her brother Jason, due to his drug addiction and their mutual disrespect of each other's boundaries. Both had no qualms going into each other's room, stealing and breaking each other's belongings. Some glimpses of that were seen in "The Goodbye Look," "My Name Is Trouble," and "Surface Tension." In one instance, Alison had fled one of her brother's house parties in tears, blaming her distress on Jason and his friends' invasiveness in her room, but left the particulars vague.

Autopsy and Death
Alison died of suffocation, which is revealed in "The Jenna Thing" and mentioned once again in "For Whom the Bell Tolls." More information on her death is revealed in "Save the Date:" Alison had been hit from behind or was running away when she had been hit on the head. She had been hit so hard her cranium was damaged, and her skull had been lodged in. The wound had come from a curved, blunt object (which Spencer believes to be her old field hockey stick). However, the hit had not killed her immediately. After being exhumed, her lungs were found to be filled with dirt, implying that she had been inhaling dirt in the last moments before her death. This basically means her assualtant had hit her, paralyzed her defense, and proceeded to bury her alive. She had suffocated in a matter of minutes. We later come to find in "Over My Dead Body" that the "curved, blunt object" actually wasn't a field hockey stick, but a shovel. Alison was buried by the same object that damaged her head. People say it was her sister, who was the real Alison, who kiled her, and that the person who is dead is the evil twin courtney.
