We are so close to finding out who "A" is on Pretty Little Liars! Season 2, Episode 25: “UnmAsked” can't come soon enough. If you can't hold out until the episode airs to find out more about what happens, we've collected all of the sneak peeks right here, so you can watch them over and over looking for clues. (We can't be the only ones who do that, right?)

Don't worry spoiler-phobes, this one's for you: We won't mention anything that isn't explicitly stated in the official promos!

First, the girls receive a message from "A.” It’s an invitation to Rosewood's masquerade ball, and a note telling them to be there at midnight. "'A' wants to play hide and seek," Emily (Shay Mitchell) concludes. We're guessing this game gets dangerous.

Spencer (Troian Bellisario), for one, is determined not to take "A"'s latest threat lying down. She's determined to "unmask this bitch once and for all." You go, Spence!

Finally, in this preview from Canada's MuchMusic, we hear someone who sounds like Spencer say "'A''s dressed as the black swan." Does that mean "A" has to be a girl? Maybe...
