As most Pretty Little Liars fans know, the Season 2 finale (Season 2, Episode 25: “UnmAsked”) is "A" day, aka the episode where we finally learn who has been harassing the Little Liars for two seasons.

In this sneak peek of the episode, the Liars worry about what "A" has planned for them at the masquerade ball that "A" has demanded they all show up to. But it sounds like "A" should be the one who's worried, because Spencer (Troian Bellisario) is on a warpath, declaring that she and the other Liars are going to "unmask this bitch once and for all."

If there is one thing two seasons of Pretty Little Liars has taught us, it's that Spencer gets what she wants when she sets her mind to it. "A" may have finally overplayed his/her hand...
