17. The Bin of Sin

'A' has decided to make Hanna their scapegoat, leaving her in a state of panic. Caleb corrupts the storage facility's data and dissociates Hanna's name from 'A's unit. The other girls want to tell Detective Tanner about Mona's laptop and let the cops do the rest. Hanna is unsatisfied with this plan. Secretly, she gathers the equipment she'll need to empty the storage unit. Caleb tries to talk her out of the idea, but ends up agreeing to help her. Aria shows Ezra her Talmadge letter, and he initially takes it well.

Upon reflection, though, he finds some truth in what Aria wrote about their relationship. Ezra says that Aria shouldn't be held back by him when she goes to college next year. Talia acts strangely at work, and Emily assumes she has a crush on Ezra. When confronted, Talia admits that she's really interested in Emily. Ashley wants to agree to Ted's marriage proposal. She officially quits her job at Jason's real estate office, intending to forget that anything happened between them. On her way out, Jason steals another kiss from her.

Hanna and Caleb break into 'A's storage unit, finding it empty apart from the mysterious barrel in the middle of the room. They are forced to abandon their plan to move the barrel when they run into Detective Tanner and Toby. Tanner looks inside the barrel, but neither Toby nor the audience sees its contents. Spencer sees that Mona's laptop is on the move and assumes that Hanna went rogue. She, Aria, and Emily follow the laptop to an abandoned ice cream factory where they find the rest of the evidence from 'A's storage unit.

On the laptop, a looping video plays of Hanna explaining her plan to Caleb earlier that day. 'A' shuts Aria and Spencer inside an industrial freezer, and Emily arrives just in time to save them from certain death. Spencer warns Hanna about the recording 'A' has of her. Hanna accuses Spencer of letting Toby know about 'A's storage unit, but Spencer denies this. She defends Toby's recent allegiance with the police despite taking issue with it herself. ' A' ending: 'A' lurks around the ice cream factory with a black light and finds hand prints left behind by the liars.
