[The following story contains spoilers from the midseason finale of Pretty Little Liars. Read at your own risk.]
Pretty Little Liars executive producer Marlene King warned us that the midseason finale would include a major shock, but that didn't keep our jaws from hitting the floor when we learned in the final seconds of the episode that Toby Cavanaugh (Keegan Allen) was the betrayer.
Pretty Little Liars is nearing its summer finale when one of 12 possible people will make the ultimate betrayal.
Although at the end of last season, it was finally revealed that Mona (Janel Parrish) was "A," there are still plenty of mysteries to be solved. First, there's the new person calling themselves "A" who continuously torments Aria (Lucy Hale), Emily (Shay Mitchel), Spencer (Troian Bellisario) and Hanna (Ashley Benson). Then there are the unsolved murders of Alison (Sasha Pieterse) and Maya (Bianca Lawson).
Pretty Little Liars' second season finale will finally answer one of the show's biggest questions: Who is A?
The ABC Family drama began a year after the murder of Queen B Alison (Sasha Pieterse), when her surviving quartet of friends began receiving mysterious texts signed with the letter "A." When the sender of those messages is revealed in the Season 2 finale (Monday, 8/7c), executive producer Marlene King says viewers won't feel blind-sided.

Pretty Little Liars star Sasha Pieterse has two words of advice for viewers watching the Halloween episode: Pay attention.
"It amplifies evidence and also a new suspect arises," Pieterse says. "This person is someone you haven't really thought of before, or if you have, there's not much evidence to back it up."

Here's why Pretty Little Liars has gotten us — and millions of other fans — hopelessly hooked.
