In this sneak peek for the Pretty Little Liars Season 3 premiere (Season 3, Episode 1: “It Happened ‘That Night’”), Aria (Lucy Hale) is taking a simple trip to the ladies’ room, but winds up screaming instead.

After twisting the lock and realizing that it doesn’t work, she hears someone walking through the bathroom and notices they’re dressed in all black, with black shoes. After she struggles with the lock again, the scary figure stands right outside her stall as Aria screams for help.

Who is the mysterious person stalking her in the bathroom? Check it out in the clip below.
