Aria Montgomery
Aria Montgomery (Lucy Hale) moves back to Rosewood with her mother Ella, father Byron, and younger brother Mike after an extended absence in Europe following Alison's disappearance. Aria begins a romance with a man who turns out to be her new English teacher, Ezra Fitz. She immediately receives a message from "A" taunting her about the secret romance. Aria and Ezra struggle with the forbidden nature of their relationship as Aria is tormented by keeping the secret of her father's past affair from her mother. As she decides what to do with the information, she finds that "A" has beaten her to it in a tell-all letter to Ella. As her family starts falling apart, Aria runs to Ezra's apartment to find him not there. After Ezra leaves, she becomes romantically involved with a student, Noel Kahn. As things turn out great between her and Noel, Ezra returns. Troubles arise as she is caught in a love triangle, with Noel and Ezra. She chooses Ezra and one night while kissing Ezra in his car, Noel sees this and blackmails Ezra for good grades. Once Aria discovers this, she cuts things off with Noel. In more recent episodes, Aria has been having trouble maintaining her relationship with Ezra a secret, especially after accidentally sending a romantic text to her mom meant for Ezra. In the latest episode, Aria leaves Ezra's apartment only to been seen by Garrett who pays Ezra a visit and says, "Let's talk about one of your students..." Luckily, he was only there to talk about Spencer and what's been going on lately with the investigation. Ezra got a transfer to Hollis College so he is no longer Aria's teacher so he says that they can have a public relationship and the couple are ecstatic about this. Until later on, Aria finds out that Ezra did not divulge information that he and his ex-fiancée were going to be teaching together at Hollis College and Aria saw this as a betrayal by omission. However, the two later get back together. Aria also befriends Jason DiLaurentis, Ali's brother, who has moved back to Rosewood. It appears that they may have a romantic relationship at some point and Ezra asks Aria if he should be worried about Jason, which Aria denies. However, Aria still spends time with Jason despite the fact that her friends think that he may have something to do with Ali's disappearance. Soon after Jason kisses Aria without Ezra's consent. She is threatened by "A" to reveal the secret. Also, Spencer and Emily snuck into Jason's shed and there was a darkroom of pictures, but all the pictures were of Aria when she was asleep. Which led Spencer and Emily to believe that Jason is "A". Aria and Hanna don't know about that yet. More problems might arise in Ezra and Aria's relationship when Aria sees Ezra with his ex-fiancee. Aria will be involved in another love triangle with Jason and Ezra. In "Touched by an 'A'-ngel," Ezra tells Aria that it is time for people to know about their relationship, starting with her parents but because Aria's mom saw Spencer in the car with Ezra she starts to think about the rumors that was said to her about Mr. Fitz being in relationships with his students.

She asks Emily to come along for support but Paige does not show up at the meeting. In the end Samara and Emily become friends and Paige is jealous of this. Samara and Emily eventually end up going out. Besides Aria, Spencer, and Hanna, Emily has told Samara about the fake Danby scholarship letter. Emily's mother Pam is thrilled about her daughter's "acceptance." However, due to stressing herself out with swimming, she collapses in school.

Spencer and Wren do kiss and are caught by Melissa, who insists that Wren move out. Spencer starts dating a worker at the country club to which her family belongs, and later hides from her friends the news that her mother has breast cancer. Her field hockey coach is her sister's ex-boyfriend, Ian, who both Ali and Spencer had a crush on. Spencer and Ali were always competing. For example, Ali was on the Varsity team in 7th grade and Spencer wasn't. In the beginning of the series, Spencer was against Emily hanging out with Toby but eventually grew to like him and has been spending more and more time with him. In "A Person of Interest", they spend time together in a motel room, as seen as Spencer's parents have a hard time understanding her connection with Ali's murder. Spencer and Toby play scrabble, sleep in the same bed and eventually kiss near the end of the episode. In the following episodes, Spencer, after suspicion continues to take a toll on her, is told to stay away from Toby for her own good. She then makes an arrangement to see him in private at the town's festival, only to be sent a fake text (presumably from "A") telling her to meet Toby in the clown house. When she enters, she is locked into a small space. She is found by Ian, her mother, and her sister and when leaving she sees Toby and almost leaves without speaking to him, but she then rushes to him, hugs him and kisses him in front of her shocked family.

The rest of the girls arrive having been to the forest, and see the dead body and they call the police. Later on when the police arrive they go in and the body is not there, leaving the rest of the town to think that the girls are liars.

In season 2, Spencer and Toby are dating.Toby does some yard work for the Hastings and digs up Spencer's old field hockey stick which she gave to Ali before she died.

Spencer later discovers that Wren came back to Rosewood for her. In order to keep Aria away from Jason, Spencer will inform Ezra that they found pictures of his girlfriend Aria in Jason's shed.

Alison DiLaurentis
Alison DiLaurentis (Sasha Pieterse) was the former leader of Rosewood's premiere clique. Ruling the group with an iron fist, the vicious but charismatic Alison had gone missing during a slumber party; a year later, her disappearance was still unsolved. When Aria, Hanna, Spencer, and Emily begin receiving threatening messages from "A" reminding them of their darkest secrets, they suspect that "A" is Alison, in whom they had all confided. But, Alison's body is soon discovered buried in her former backyard. It is revealed (by a video "A" sent the girls on Spencer's computer) that Alison may have had a relationship with Melissa's brand new husband, Ian, and that Ian might have been the one who killed her. It is revealed during a flashback that Ali and Emily kissed. Emily had strong feelings for Ali, but Alison didn't feel the same, saying, "I like boys, Emily. And trust me, if I'm kissing you, it's because I'm practicing for the real thing." She also pressured the girls into doing things, like going along with her when she exploded Toby's garage. Ali was also with Aria when she saw Meredith and Byron kissing. Alison comforted Hanna when Hanna binged on eating a whole pie. She said, "I can teach you how to make it go away" which meant that she taught Hanna how to make herself throw up. She taunted Lucas, and broke up Noel and his girlfriend, saying that she did it for Aria since she had a crush on him. "I only kill when we need food," she said. "Or when I'm bored." It is later revealed that Alison was in a relationship with Ian after the girls see a tree with "Alison + Ian" carved into it. The girls' therapist suggests Hanna talk to an empty chair and pretend Alison is sitting there. Hanna says "You were the best friend I have ever had, but you were also the worst enemy I ever had." Alison, responds with "I'll always be with you, I'm the only that can make you happy, the only one to tell you the truth, I'm the only one you can count on". Hanna sends her farewell towards the imaginary Alison by saying, "You're gone and I'm so over missing you". After reading Alison's autopsy, the girls discover that Alison was attacked from behind and buried alive which is what killed her not the head wound.

"A"
"A" is the main antagonist in the series. From the opener, "A" sends messages to Aria, Emily, Hanna and Spencer taunting them about knowing all their secrets and plans to make their lives miserable, as Alison and they had made everyone else's lives miserable. At first, the girls suspected Alison as "A", but her corpse was unearthed in her backyard. The most possible suspect is Jenna Marshall, who was a victim of Alison's prank. With Jenna's vindictive tendencies, she could be "A". During the mid-season one finale, while Ezra and Aria were in the car, Noel Kahn wrote "I see you" on the back of Ezra's car, prompting Hanna to believe Noel is "A". The girls continually think Noel was "A", possibly but "A" also went to great lengths to destroy any evidence, like cutting down a tree that had "Alison + Ian" carved on it. However, "A" has also done good things for the Liars, such as saving Ezra and Aria's relationship by framing Noel for cheating on midterms. Although "A" did some good, "A" decides to blackmail Hanna into doing things she doesn't want to do, like torture Lucas and almost ruin Aria and Ezra's relationship. In return, "A" gives her money, to help combat the financial difficulty that her and her mother are going through. In the season one finale "For Whom the Bell Tolls", "A" saves Spencer from dying by pushing Ian off the ledge near the bell in the church while he was trying to push her to her death, prompting Ian to be hung by the ropes of the bell. When the police come, however, Ian's body is nowhere to be found, and neither is "A". "A" has taunted Aria about her relationship with Ezra by sending Aria a text about their relationship which led Ezra to break up with her and the fact that she knew about Byron's affair with Meredith, Hanna about the fact that she shoplifts, and was bulimic, Spencer about her flings with Ian and Wren, and Emily about her sexuality, and faking a college acceptance letter. While the girls went back to the graveyard at night, most likely A turned the video of Ian supposedly strangling Alison on with the real ending of Alison getting back up saying "Thank you for coming tonight" to Ian and her walking away. After discovering that Alison was ambushed and buried alive, the girls now think that whoever is "A" must be the real murderer of Alison and framed Ian for Alison's murder. In "Touched by an 'A'-ngel," "A" discreetly gives Emily massages when she arrives at a spa appointment to shake her up. Later "A" is seen talking to the Liars therapist. In the episode, "I Must Confess," the girls realize that they have made a crucial error by telling Dr. Sullivan about "A". After "A" sends Dr. Sullivan a message saying, "And I'm the first person you've told about this?", on a loop, Dr. Sullivan then decides to do a little bit of investigating herself, realizing that she knows who "A" is. This then leads to "A" kidnapping her and "A" taking her key to the building, and taking the files about "A's" identity and sessions with Dr. Sullivan, leaving the girls with no evidence about who "A" is. The story is continued in episode "Over My Dead Body."
