Pam tells Emily that someone has been breaking into everyone's houses stealing camping supplies. Hanna's father returns to town, but Hanna doesn't trust him after seeing him marry into a new family. Mona tries to get Hanna's forgiveness by talking to Aria for advice;— but Aria tells her that she's not allowed to talk to Hanna, so Mona's on her own. Mona also asks Aria to pick a goodbye present for Ezra's last day, since she knows him better "from the play." Spencer thinks that her sister is hiding something to protect Ian.

Spencer tries to strike up a conversation with her father, as he searches for an unhealthy night-time snack. The Liars meet with Jessica DiLaurentis for lunch shortly afterwards, despite their awkward reservations. She then presents the girls with presents; four high fashion dresses and asks the girls to model them in the fashion show. Just before the show, Spencer hands Noel the disc Mona asked her to deliver to him. In the corner of the room, Jessica and Peter have an argument. The fashion shows starts, and later the tribute to Alison begins, with her image prominent on the runway screen and the girls walking the runway in her dresses. Suddenly, the image changes so as to make Alison look like the devil, with fire around and peeling black eyes. The screen flashes "the bitch is dead," and the music changes from sentimental to hellish. Spencer runs to Noel to make him turn it off, but he claims he can't. She unplugs all the wires around his equipment until the images and sound effects stop.

"Picture This"

Spencer begins to suspect Jason after finding his broken hockey stick in her yard, and deciding that he was the one who stole the missing page in Alison's autopsy file. While spying on him in his front yard and seeing how protective he is over the shed in his yard, she and Emily decide to break in. While in the shed, they find pictures of Aria while she is sleeping, and a box of cameras and spying equipment. This leads the girls to realizing that Jason is spying on Aria, and could be spying on all of them. Meanwhile, A put steroids in Emily's pain cream which caused her blood tests to show signs of human growth hormones. Hanna's mom allows Emily to have Samara and some of Samara's friends over for a small get together, and A forces Emily to give her phone number to one of Samara's friends, Zoey. Samara's other friend catches Emily giving Zoey her number and then later tells Samara, which ends Emily's relationship with her. Aria begins to have continuous dreams about Jason, which she feels is threatening her relationship with Ezra. Later at the park, Jason kisses Aria, but she tells him she is already taken, leading Jason to think she's afraid of him.
