Emily and Spencer are in Spencer's room talking about Lesli, who Spencer believes to be A. Emily tells Spencer that it's crazy and that she was in a room with this person, to which Spencer replies "and they were wearing a mask". Spencer says that Mona has always been shady about how she met Lesli and now they know why - they were sharing a straight jacket. Spencer also adds that Mona only got a gas mask and was able to pass out food, while the rest of them were making sure they still had kidneys. Emily asks what's taking Hanna so long and Spencer says that she's probably trying to drag Mona there on a leash. Emily asks if Spencer believes in her heart that Lesli is capable of creating a bunker and having more equipment than the CIA, to which Spencer says that Mona was able to maintain a 4.0 GPA and perfect hair while she was tapping Rosewood's police calls. Emily replies that they jumped on the "Andrew is A" train, but Spencer says that he didn't have a motive and Lesli does - she thinks that the girls killed Bethany.

Hanna arrives without Mona, saying that Mona's mom busted her for sneaking out to Radley and isn't allowed to leave her room. Emily says she has an appointment with her mom and Doctor Sullivan and Hanna asks where Aria is. Spencer tells her that Aria is at Hollis College putting Clark's negatives back. Hanna asks if they are going to Philly to catch Lesli in the act, but they don't respond in the affirmative, angering Hanna.

The scene cuts to Kenneth DiLaurentis opening his mailbox and seeing what winds up being a birthday card on his windshield. He opens it and becomes very nervous. Emily is riding her bike to go back home and Kenneth demands to know if anyone has been near his house, prompting Emily to say that she hasn't seen anyone.

Aria is seen slipping Clark's negatives back into his cubbyhole and Clark asks if she was looking for something. Clark says that if she was that uncomfortable by him taking pictures of her, all she had to do was say so; he then jokes that she didn't have to go klepto. Clark invites her out to get bagels, but she declines.

Hanna is in her kitchen looking at the Harwich University site on her laptop, and discovers that Lesli is a teaching assistant in her science department. She then sends Emily a text letting her know what she found out. Caleb shows up at the Marin household and Ashley invites him in for breakfast; he greets Hanna who acts dismissive towards him. He sees a lump on her neck and asks what it is, prompting Hanna to say that she just woke up. Hanna tells her mom that she won't be staying for breakfast because she has to meet Spencer for Spencer's appointment in Philly and tells Caleb she'll call him later.

Emily is now in her bedroom, as Sara asks her which top she should wear for her first day working for Caleb. Emily tells Sara that her office is where he plays Grand Theft Auto in his boxers; Sara tells her she doesn't want to screw up on her first day and Emily tells her that everyone does. Sara takes off her hoodie, leaving her in just a bra, and Emily stares at Sara's tattoo. Emily tells her that her tattoo looks great and jokes that she'll have to wear long johns in August so no one sees her "courage". Sara is about to apply ointment to her tattoo when Emily hesitantly asks if she wants help, to which Sara agrees. The intimate moment causes both girls to become uncomfortable so Emily steps away and tells her she should wear the plaid top.

Spencer is at her house when she hears a knock on the door, the person revealed to be Dean. Dean tells her he wanted to drop something off, so Spencer invites him in. Dean wanted to give Spencer a book that his sponsor gave him, then asks if she's been sleeping without help and Spencer says she hasn't. Dean also gives her brownies, as she receives a text from Melissa. Spencer tells him that the principal has asked her to be the "poster girl for trauma", and Spencer isn't interested. She says that she has a lot of incompletes and isn't ready to pretend like it's over when it isn't, causing Dean to tell her not to do it. Spencer gets another text from Hanna, then tells Dean that she'll see him at the meeting later.

Hanna is standing across the street from a sushi bar on the phone with Spencer asking where she is, causing her to say that she's on her way but got caught up.

Caleb and Sara are sitting in his office and he tells her what she's going to need to know. Caleb says that everyone wants a response that will adjust a picture to a different screen, explaining that a picture of "Kimye" will look the same on your phone/smartpad/computer. Sara asks what Kimye is, causing Caleb to tell her "Kanye and Kim" and when he receives a blank look from her, he says "right". To make her feel better, he says that she doesn't need to know: no one does. Sara asks what Caleb knows about Alison: "Normally I wouldn't ask, but when you're forced to answer to someone else's name and wear their clothes, you become curious about her". Sara says that Emily shuts down anytime she asks about her, then asks Caleb is he thinks Ali knows who did this to them. Caleb tells her that he wish he had answers for her but he's on the outside too.

Emily asks "doesn't your dad live in Florida?" and Nicole replies that he does but she didn't want to have to do this over the phone. Nicole tells Emily about a program in Thailand and asks Emily if she'd like to go, but Emily tells Nicole that she's just getting used to being back and that she's trying to help a new friend out.

Spencer says that her school is, prompting Sara to say that Emily told her and calls her the brainiac.

Caleb is at the Brew and sees a book on the table. He opens it up and Ashley walks over to him. Noticing the book, she tells him she doesn't need it and that they may never know what happened to her. Caleb says he's not trying to smother her and Ashley says she thinks that Hanna knows too. Ashley says that, after her and Tom's divorce, Hanna would watch movies with her and cry at the funny parts and laugh at the sad parts. Caleb feels like he's lost her and Ashley thinks that the old Hanna is still in there.

Aria is in her room and asks how A knew they'd all be together and Emily says that that's how it's always been. Ezra drops by and said she left her photo application at the Brew and that he needed a recommendation, so he wrote one for her. He admits that he embellished slightly, when Aria asks when she had a solo exhibit at the Brew. Ezra notices the doll and says that it's disturbing.  

Spencer goes home and sees Dean, who is upset with her because she missed the meeting. She apologizes but says that she'll write the speech and he says he doesn't care about the speech. He says that, in his life, when someone doesn't show up or answer their phone, there is a real possibility that they're lying in a gutter somewhere. This upsets Spencer, so she apologizes again. Spencer asks if he'll come in for coffee, but Dean says he can't see her anymore because any time she's near him, he wants to kiss her. Her having a boyfriend isn't the problem, the problem is that he doesn't care. She takes a step back and Dean leaves.

Hanna is in her room and Caleb walks in behind her, freaking her out. He tells her that Ashley made him a key, which doesn't surprise Hanna. He tells her to knock it off, prompting her to say that she's not the one who showed up at someone's door for no reason. He grabs her arm, says that he has a reason and kisses her. The two make out and move over to her bed.  

Sara is furiously scrubbing Emily's floor and Emily asks what happened to her. Sara says she doesn't know if the accident happened on purpose. She was riding her bike and felt like she was being followed. It sped up and the mirror hit her arm. Emily holds up her phone, showing Lesli's car, and asks if that was the car that hit her and Sara says she thinks it was. Emily tells Sara she's safe and that they can get out of Rosewood, but Sara says her mom won't let her leave the country. She also adds that no one can help her.

Nicole goes back to the Brew with pictures and Emily informs her that she's changed her mind because she can't leave Sara behind. Nicole asks if Sara is capable of returning Emily's feelings and Emily says she's not feeling that way.  

Back in the lab, Hanna sees a bunch of rats in their cages and a raccoon. Hanna decides to let the rats out, but the raccoon gets out as well. Trying to lure them back into their cage, Spencer takes Hanna's cheese puffs and throws some on the floor. A rat climbs onto Aria's shoulder

causing them to freak out, as the lights go off. A light turn backs on and Mona asks if they're lost their minds. Mona says she shut the lights off so the campus police wouldn't see them, but the girls believe her to be working with A who they strongly believe is Leslie. Mona says that Lesli hated Bethany and that she's pretending to be stable. It's revealed that, the night Ali disappeared, two people escaped from Radley: Bethany and Charles. Spencer hands Mona Charles' medical form to prove that he was dead, but Mona quickly shoots the idea down upon seeing the medications Charles was on. She explains that no one would want his liver and he wasn't an eligible donor. The girls claimed that they had a picture that A was a girl and Mona says that if they had a picture, it's because A wanted to be caught. Campus security shows up but the girls stay hidden.

There is is a montage of scenes: Spencer is in her meeting and there is an empty seat, believed to be Dean's. Aria walks to the Brew and sees Ezra and Nicole laughing together. Emily walks into her room and finds Sara sleeping; she tries to check if Sara has been chipped but Sara wakes up and kisses her.
