Jenna Marshall

"We've all made mistakes. Remember, I'm still paying for yours."

- Jenna to the The Liars:

Jenna Marshall is the younger stepsister of Toby Cavanaugh. She was the victim of a prank orchestrated by Alison that resulted in her losing her sight. She is portrayed by Tammin Sursok.

Biography
In October 2008, Jenna moved to Rosewood after her mother married Toby's father. She quickly became popular at Rosewood High School. Alison invited her to join her group of friends but she declined. This led to a long-term rivalry between the two. Jenna is a very aggressive and manipulative person. She forced her step-brother, Toby, into a sexual relationship with her and threatened to accuse him of forcing himself on her.

After being blinded by Alison and her friends, Jenna developed a hatred and grudge against all of them. Jenna seems to have been involved with the N.A.T. Club before Alison went missing. She was not sorry for Alison's passing and has continued to keep the Liars on her radar to keep them from revealing her secrets.

In late Season 2, Jenna got an eye surgery and was fully able to see throughout the third season. However, going into Season 4, the operation proved to only have temporary effects as she began to lose her sight again. She used to date popular jock Noel Kahn and used him to regain her popularity in school.

While she was still blind, Jenna was made to believe that Garrett (whom she dated) killed Alison. Throughout the first three seasons, Jenna thought she knew how Alison was killed. However, what she thought she knew was incorrect.

Jenna has almost been murdered twice: once in Season 2 by being lured to and locked in a burning house and again in Season 4, after being knocked unconscious and left in a lake to drown.

She was in a coma due to being struck on her head and, after waking up, was living in New York, but is back in Rosewood for Season 5. She is helping Sydney and Mona take down Ali, and is also grieving Shana's death.

Series
Pilot Jenna is seen being guided into Alison's funeral by Toby, much to the surprise of everyone. She is later lead out to a car by Toby moments after Wilden confronts the girls.

The Jenna Thing

Jenna walks in the Apple Rose Grille while the liars are there. When she sits down, they silently get up and leave.

Aria invites Jenna to sit with her and the others in the school cafeteria. It is an awkward lunch, as Jenna purposefully frightens the girls makes reference to the group's changed dynamic since Alison's death. Jenna tells them that Alison came to visit her while she was in the hospital. She says that everyone misunderstood Alison but that she knew exactly who Alison was. The girls are silent as they flashback to the fateful events of that night. At one point, Jenna breaks the silence by picking up Spencer's beeping phone, when she receives a text, with Spencer paranoid to receive a text from "A" with Jenna in such close proximity. Obviously, no one found out about "The Jenna Thing," but with Toby knowing, they could never be sure about when the secret was going to slip and if "A" would ever play that card.

When Spencer is out for a run she sees Jenna sitting on a bench. Jenna is using a phone for the blind and says "Send text now." She turns and looks at where Spencer is standing.

To Kill a Mocking Girl Jenna walks into school with Toby in tow.

Jenna is walking down the hallway while the girls are whispering to each other. She comments such as "Whisper, whisper, whisper. Almost feels like Alison's still here,"

Later when Emily comes to thank Toby for helping her with Ben, Jenna is present which is unknown to Emily. After Emily leaves Jenna questions Toby about the reason why Emily is thanking him but he tells her it isn't what she's thinking.

Reality Bites Me Jenna is seen by Hanna on her way to work at Dr Ackard's office. Jenna enters the elevator and puts on her lipstick. SHe asks Hanna if she likes the color. It is unknown if Jenna knew she was talking to Hanna.

There's No Place Like Homecoming After the homecoming dance, when Emily is home from being hospitalized, Jenna visits Emily with her seeing eye dog, Shadow. She comes under the guise of being sympathetic to Emily's plight, bringing cookies to bed-ridden Emily (which Emily does sample, despite Spencer's distrust towards them later). She knows that Toby's psychological profile is missing because the cops went looking for it, and knows that the Liars have the file, having overheard them talking about it at Homecoming. She wants Emily to return the file to her, so that she can protect her secret of having forced her step-brother into a sexual relationship. Emily is open to fulfilling Jenna's request, as she feels partially responsible for Jenna's accident, something Jenna does not fail to mention repeatedly. Emily tries to get the file back, but cannot contact the girls while her mother is around. Aria throws the file into the river. (It seems the file makes its way into "A's" hands anyway, when a figure is seen gingerly retrieving the pages from the water.) When Jenna asks for the file after Emily is back at Rosewood High, Emily vaguely tells her that the file is gone, and Jenna is put off, being put in the position where she is forced to trust Emily.

Please, Do Talk About Me When I'm Gone

Although Jenna is resentful towards Alison and her memory, Jenna volunteers a speech at Alison's memorial dedication. She shares only kind words, mentioning Alison's visit to her in the hospital, claiming that Alison made her stronger and more in touch with her identity. It is unknown if she did this because she wanted to throw off the Liars or because she meant it.

Salt Meets Wound When Jenna discovers that Toby likes Emily, she is very jealous. Jenna tells Toby she turned him in to the police so he would come home and continue their relationship. Jenna also proves she can be slightly abusive and controlling, as she slaps Toby when he tells her he will "never touch her like that  again.", and asks who he thinks he's talking to.

The New Normal

When Toby's house arrest bracelet is to be removed, she hails a taxi cab, so the two can ride there together. She is very upset when he declines her offer, choosing to go with Spencer in her car, rather than with her.

The Badass Seed Jenna offers to play flute for the school play, "The Bad Seed" and tells Mr. Fitz that she is fascinated with the play and its theme, the nature of evil. She is seen talking to Ian in the episode by a similar name,, taking a "Neuman's" shopping bag from him, the contents not revealed.

With Mr. Fitz as her guide, Jenna writes an essay to be submitted to an essay contest with vague references to the event that blinded her. The essay centers around a blind girl that senses more than seeing people do. It seems from the essay that the incident that blinded her was not an accident, although it leads Mr. Fitz to believe her brother is guilty, not the girls. Ezra is fascinated by the story and believes it has a winning chance. At the end of the episode, Aria confides to Mr. Fitz about who the real perpetrators were. Jenna makes references to Aria's romantic relationship with Mr. Fitz, scaring Aria, because it is unclear how she knows about the couple.

Someone to Watch Over Me Jenna is seen with the owl that Hanna thought was a gift for her from Caleb. However it is a flashdrive that Jenna gave to Caleb to put information on and return to her. As the girls put the pieces together they realize that Jenna had been paying Caleb to spy on Hanna and look for a key in her house that she thought Alison had given to one of the girls. A hurt Hanna slaps Jenna for what she did and Jenna cries for it.

For Whom the Bell Tolls Later, after discovering Jenna and Toby's relationship caught on tape, the girls realize what Jenna was seeking in hiring Caleb. They decide to approach her for answers. Jenna is very frightened, because she knows that she could easily go to jail for her crimes, so she seems genuinely contrite. She reveals that Alison indeed visited her in the hospital, but to threaten her to never tell anyone about her role in the prank or risk Alison's revealing the footage of Jenna sexually abusing her step-brother. Her supposed last words to Jenna were, "If you ever come back to Rosewood, I'll bury you." They feel her story explains why she would have spoken at Alison's memorial and attended her funeral, returning to Rosewood for Alison's burial instead. They are thus far satisfied by her story. However they did not know the extent of Jenna's deceptions and actions at that time.

It's Alive
 * -|Season 2=

After Spencer's near death experience, the girls are taken to the precinct for questioning in. However, before taking the girls to the station, Garrett pulls over to review with the girls his expectation that they omit his involvement with bribing Ian from the story. Mysteriously, Jenna is secretly standing nearby as Garrett preps the girls for interrogation.

My Name Is Trouble

Jenna takes a pottery class at Hollis College, alongside Aria. Aria pretends to be Anita, so as to hide her identity from Jenna. It is interesting to note that when she was talking to Aria, thinking she is Anita, she shows a much sadder and more vulnerable side then she usually does. She has made a beautiful pottery piece, but is frustrated that she cannot see anything, not even the shadows it produces when lit. Aria tries to comfort her and praise her work, but when Jenna discovers that it was Aria, she goes ballistic, screaming at her to get out.

Surface Tension

Aria finds that pottery piece among Mike's belongings. She assumes that Mike stole it from the Cavanaugh house, but he is sure that he stole it from Garrett's apartment. This causes Aria to realize that Garrett cannot be trusted.

Save the Date

The girls see Garrett pull up to Toby and Jenna's House in his car. It could go either way, considering Garrett's parents live across the street. However, Garrett heads for Jenna's place, and the girls follow to watch. Inside, Jenna removes her robe to reveal the black lace lingerie she was seen buying in an earlier episode. She removes her glasses, and the two start to kiss passionately.

Garrett and Jenna do a lot of spying together in Garrett's sports car. There, they constantly refer to "The Jason Thing," an ill-defined incident that may or may not be linked to Alison's death. When Jason kisses Aria, Jenna expresses her fear that the two will hook up, and Jason will reveal his secret to Aria.

The latest development is the possibility that Jenna will have a cornea replacement, which means that she may regain her vision at some point in the near future. Toby fills Spencer in on the details of the matter after she overhears Jenna discussing the possibility with a nurse, while all the girls are in Rosewood Community Hospital.

I Must Confess

Jenna teases the girls after the assembly, asserting that Alison could have used the lesson on bullying. Emily shoots the same accusation back at Jenna and snidely tells her to move her walking stick.

Over My Dead Body

Someone shows up to the precinct, prompting Garrett to say "You shouldn't be here." He was presumably talking to Jenna. Garrett then leads her to the room on the other side of the glass of the investigation room. He locks the door, and Jenna laments that she cannot see their faces. Jenna is eager to get with Garrett, but Garrett reminds her that he was patient enough to wait to get into the storage room; he can certainly wait a few more nights. Their conversation also reveals that they wrote the note to Jason, making him suspect that he had killed his own sister, and that Jason has figured out that he is not the culprit. Garrett gives Jenna a note and instructs her to take it home and burn it. Jenna asks whether it is page 5, and Garrett doesn't contradict her assumption. Before kissing Garrett goodbye, Jenna remarks, "She deserved to die like that."

The First Secret

In the prequel episode, Jenna is first mentioned by Toby in conversation to Emily. While unpacking some of Jenna's things from the moving truck, he describes her as someone who gets whatever she wants.

Later, at the costume shop, Alison spots then-new girl Jenna buying her one costume—a "Lady G." costume. She tries to intimidate her to buy a different one, declaring that that is her own costume choice for this year. The new girl noncommittally agrees to think about changing her decision, but turns her attention away from Alison. Before walking away, Alison offers her name, to which the girl replies that she already knows it, and her own name is Jenna. They smile pleasantly, if not falsely, at each other, and Alison strolls away.

At Noel's bash, Alison notices Jenna dressed as Lady GaGa after all. And Noel, dressed as a gynecologist, goes right to her. When a Lady GaGa song starts playing, Ali approaches her herself. Jenna is flanked by boys, but they all scram when Alison orders them to. Alison offers to befriend Jenna, thereby making her popularity in Rosewood a sure thing. However, Jenna turns her down and says that she likes to pick her own friends. When Jenna saunters away victoriously, Mona declares her the best Gaga, and the two introduce themselves, seeming to start a friendship.

Outside on the porch, a sulky Ali jealously calls Jenna a slut. Back in the party, Emily is seen slow-dancing with Ben on the dance floor. Jenna is seductively dancing nearby, and Emily ogles appreciatively at her curves and moves. Alison turns her eyes from one to the other, approaches Emily, and alludes to her secret sexual orientation.

During the episode, someone lures Jenna to the house of Jason DiLaurentis and then sets it on fire, trapping Jenna inside with the intent to murder her. She is rescued by Hanna, who happened to be near the DiLaurentis household. She goes to the hospital and has to stay there under observation. This marks the first time in the series that Jenna seems to be frightened. She asks to see Aria, Spencer, Hanna, and Emily. While they're in her hospital room, she asks if it's true that Hanna pulled her out of the fire. When Hanna confirms this, Jenna asks her why she did it and she seems grateful to Hanna. Hanna doesn't answer her question, but simply responds "You're welcome."

Later in the episode, "A" is seen planting Garret's police badge at the scene of the fire, in order to implicate him in the attack on Jenna. Since Jenna is still in the hospital when this happens, she can be ruled out as the one behind the "A" scheme.

If These Dolls Could Talk

Jenna removes the bandage from her eye and cryptically begins to cry. Later, at school, she approaches the four main characters at their lunch table and apologizes for having hated them, saying that when Hanna pulled her out of the fire, she realized that people were capable of changing. However, her apology is met with suspicion by all four girls. She shares with them the "unfortunate results" of her surgery.

Later, Toby comes into her room questioning her as to why Garrett is watching their house. She says she doesn't know, and asks him to close the curtains. She pulls a slip of paper from a box on her night table, and gives it to him. Telling him that it was given to her by Garrett and was told to keep it safe. She lies, playing stupid, and claiming to not know what it is. Toby opens it revealing it to be the missing Page 5 of Alison DiLaurentis' autopsy report. They then go to the police station to give it to the police.

At the end, she is seen smacking a fly on her mirror and removes it's corpse, she turns back to her mirror with a sneaky smirk and continues to remove her makeup, revealing that she is indeed able to see. The surgery was successful after all, and for unknown reasons Jenna is lying to everyone and leading them to believe she is still 100% blind.

 * She is blinded by a supposed prank gone wrong set up by Alison with the help of the other Liars. Towards the end of Season 2 she got eye surgery that restored her vision on at least one eye. However, she still lets everybody believe that she still cannot see, with the exception of a mystery-person she meets up with in a park in the season 2 finale (later revealed to be Shana ).
 * She paid Caleb to spy on Hanna in order to keep the secret of her having forced herself on her step brother Toby.
 * She put a note in Jason DiLaurentis' pocket saying "I know what you did." The note was intended to make him think he killed his sister Ali, which she knows he did not. She did this to cover up for Garrett, her love interest at the time, because she thought he killed Alison.
 * She was slapped by Hanna after Hanna finds out that Caleb was being paid by Jenna to get close to her and to spy on her.
 * Before her blindness Jenna was shown as having the capability of giving Ali competition for the Queen Bee title, Ali gets intimidated and suggests that they team up instead, but Jenna refuses, saying that she prefers to pick her own friends.
 * Jenna is shown to be able to play the flute well.
 * Jenna uses a flashdrive in Someone to Watch Over Me. It is unclear how she can operate it without seeing, but it is mentioned that she has a special computer for the blind. In the same episode, Jenna uses Caleb's locker combination, 2-1-4, to leave something in his locker. How she opened his locker without seeing is a mystery, as the number markings are not indented very well. Another combination with numbers far from zero might have given her even more trouble.
 * Jenna thinks that Garrett Reynolds killed Ali.
 * Jenna is losing her sight again. It might have gotten worse fast because of the fire.
 * Jenna was thought to be bisexual, but due to her personality (ie. using others to get what she wants:"means to an end"), it is strongly believed she is just using Shana's crush on her to her advantage.
 * By the Season 4 premiere: "A is for A-L-I-V-E", her vision has gotten much worse, as seen by needing someone to hold onto (like in "Pilot") and the return of her black sunglasses.
 * She might have been the one that Toby saw or she's the one that hit him over the head in "A DAngerous GAme".
 * In the Season 4 premiere, Emily notices a burn on Jenna's arm. The cause is unknown, but it might have something to do with being near the lodge fire.
 * Jenna is featured as a Major Supporting Character for the first three seasons, but was downgraded to a Minor Supporting Character for the fourth season onwards.
