7. Surface Tension

Aria's parents throw a dinner party, putting Aria face-to-face with both Ezra and Jason. The awkward night is interrupted when Mike gets arrested for breaking into another house. Emily tries to get used to living with the Marins, while Hanna tries to come to terms with Caleb's "sketchy" business. While doing landscaping work for the Hastings, Toby finds an old hockey stick buried in the backyard, and Spencer's father becomes visibly nervous but burns it in the fire saying it doesn't mean anything. Toby later tells Spencer about it, and she thinks it might be the weapon used to kill Ali.

Ashley and Ella begin to wonder if there isn't something more serious going on in the girls' lives that they don't know. After searching through Mike's bag of stolen items, Aria realizes that Officer Garrett cannot be trusted, just as Spencer sits in the car telling Garrett she doesn't know if she believes that Ian killed Ali anymore. ' A' ending: 'A' injects steroids into Emily's lotion.
