If for some reason you were worried that the Pretty Little Liars Season 3 summer finale (Season 3, Episode 12: “The Lady Killer”) would be a letdown, think again.
In this sneak peek of the episode, we see Hanna (Ashley Benson) sobbing as a body is put onto an ambulance. Meanwhile, a policeman questions Emily (Shay Mitchell), asking "the deceased was a friend of yours?" and "I'm trying to understand what happened. Did you know the victim."
Emily says she DID know the victim, though she doesn't answer the friend question. Who do you think it is?
