In this shocking sneak peek from the Pretty Little Liars Season 3 summer finale (Season 3, Episode 12: “The Lady Killer”), we see Mona (Janel Parrish) in her black hoodie sweatshirt and black gloves. At first, she checks herself out in the mirror and smirks, liking what she sees. But that self-confidence all changes when she gets a phone call.

She tells whoever is on the other end, “I’m here.” After a long pause, Mona’s face falls and she seems to enter a submissive trance. “I understand,” she says.

Who do you think she’s talking to? And what are they planning?

Check out the sneak peek below!
