Alison's Dark Side Emerges in This Perfectionists Sneak Peek

Alison DiLaurentis (Sasha Pieterse) is looking to turn over a new leaf in Pretty Little Liars: The Perfectionists. She's got a new job at Beacon Heights University, and she really wants to show that she's left her high school mean girl ways behind her...but can she?

TV Guide has your exclusive first look at a new Perfectionists promo that shows Alison struggling to keep those old urges at bay, but when a student gets murdered on campus, it seems like Dark Alison might be necessary to get out of this situation safely.

At one point, Alison even tells her new students that she won't do anything she has not done before to stop the torment that's happening. For those who are unfamiliar, Alison's rap sheet includes: manipulation, blackmail, faking her own death and obstruction of justice. You know, totally normal high school hobbies.

Let's not forget that Alison also has Mona (Janel Parrish) hanging around, and those two aren't known for bringing out the best in each other. Old habits die hard... let's just hope not literally.

Pretty Little Liars: The Perfectionists premieres Wednesday, March 20 at 8/7c on Freeform.
