In less than two weeks, Rosewood residents will be going full force for Halloween on Pretty Little Liars.

ABC Family has released a scene from the episode, featuring Mona (Janel Parrish) at the mental hospital painting a paper mache head on a stormy night.

Then she starts to speak.

"I told them I wanted to do an art project for Halloween. They said, 'Art is fine but we don't like to talk about Halloween in here. It's supposed to have bad connotations for some of the patients,' " Mona says before turning around in the dimly-lit room, revealing "A."

"But I love Halloween. All the dressing up, being other people, tricks and treats, treats that turn into tricks. It's better than Christmas," she continues to say.

Why? "More makeup."
