"A" was back with a vengeance on Pretty Little Liars Season 2, Episode 18: “A Kiss Before Lying,” framing Hanna (Ashley Benson) for yet another crime she didn't commit: sending a naked pic of her step-sister Kate (Natalie Hall) around to everyone she knows. Waiting for the new episode is agony, so if you can't hold on until Monday to find out what happens next, we've rounded up all of the spoilers for Season 2, Episode 19: "The Naked Truth" for your sleuthing pleasure.

It's truth time: In this episode, the Liars will take part in Rosewood High's latest attempt to hold back the tide of teen hatred and angst that is taking over the school: "Truth Up" day. It's a day (and night) where everyone gets locked in the school and has to share their feelings in a series of adult-led exercises. Sounds like an excellent formula for explosive drama.

Is Hanna expelled? You'd think sending a nudie pic of a classmate around the school would get you kicked out, but in this sneak peek the Vice Principal takes pity on Hanna, probably because he can tell all of the adults in her life are crazy, which kind of excuses her behavior. Instead, she and Kate just have to be in the same group for "Truth Up" day. Fun!

Jason's back, tell a friend: Jason's back! And at "Truth Up" day as a chaperon! It comes as no surprise that Spencer (Troian Bellisario) will use the opportunity to try to pry some truths from him. Our girl is always proactive.

Getting the truth out of Holden? Speaking of lying men, Holden (Shane Coffey) is still not opening up to Aria (Lucy Hale), and she's not gonna take it anymore.

Will "Truth Up" day finally give us some of the answers we've been waiting for? We'll find out on Monday, February 6 at 8 pm ET/PT on ABC Family.
