Spencer Hastings is done playing Mona Vanderwaal's games. In a sneak peek from the Feb. 12 episode of Pretty Little Liars, Spencer (Troian Bellisario) confronts her arch-nemesis (Janel Parrish) and threatens to expose her true identity as a member of the villainous A-Team.
"I really want to thank you for sending the good doctor to my rescue," Spencer says of Wren Kingston (Julian Morris). "We know why you called him: he gives really good intervention."
Leaning in close, Spencer continues, "Actually, part of my treatment plan requires me to read a case study all about a deeply disturbed teenager. Wren seems to refer to her as M, but we both know that this sociopath goes by other initials as well."
Scowling, Mona replies, "Sounds riveting. But if you'll excuse me . . . "
"I do wonder, though how anonymous this patient can stay once I upload the entire case load on the internet with your photo attached," Spencer says.
Mona, appearing unfazed, looks Spencer directly in the eye and says, "And who's looking cray-cray now, Spencer? Have you completely lost it? Is that why Toby left you?"
"According to your records, Toby was never with me," Spencer says of her ex-boyfriend, who was recently revealed to be a member of the A-Team. "But my friends still are, Mona, and you are not taking away any more of them."
"And yet I don't see any of them here now," Mona retorts. "Do you still have any friends, Spencer?"
Pretty Little Liars airs Tuesdays at 8 p.m. EST on ABC Family.
