The Mysterious "A" has been harassing Hanna (Ashley Benson), Spencer (Troian Bellisario), Emily (Shay Mitchell) and Aria (Lucy Hale) for two seasons on Pretty Little Liars, and on Monday's all new episode, Mona (Janel Parrish) becomes her latest victim.
"I'm getting texts from that same freak who sent me the one about your liposuction," Mona tells Hanna in the clip (above). "It's so creepy. Like I'm being watched 24/7."
In one text, "A" attaches an incriminating photo of Hanna's mom (Laura Leighton) hooking up with detective Darren Wilden (Bryce Johnson).
"This 'A' creep expects me to believe that your mom slept with this goon to save your ass," Mona tells her BFF.
When Hanna lies and claims the image is "totally Photoshopped," Mona doesn't argue. "I figured," Mona says. "People have way too much time on their hands."
Pretty Little Liars airs Monday at 8 p.m. EST on ABC Family.
