Check out this sneak peek from the “Pretty Little Liars” Season 4 finale, titled “A is for Answers.”

In it, the Liars have tracked Alison down in her Philadelphia hideout and they confess to her that they think her mother is “A,” the person who has been torturing them since Mona stopped being “A” and went to Radley.

Alison doesn’t seem particularly surprised at this, but she says it’s complicated and sits downt to spill her guts to the Liars. Answers, indeed. Who’s ready for some answers?!

“Pretty Little Liars” airs Tuesday nights at 8 p.m. ET/PT on ABC Family.
