Check out these clips from “Pretty Little Liars” annual Halloween episode. The Season 4 installment is titled “Grave New World” and features the Liars crashing the Ravenswood Founders Day Celebration, with Ezra lurking in the shadows — and we’ll find out if Alison is really alive or not.

In the above clip, the girls wonder what kind of town throws a party in a graveyard. Um, the kind of town we want to visit on ABC Family every week, ladies. They also worry about running into “A” before they find Alison. Hmm.

Below, the girls are trapped in what looks like a basement of some kind and Hanna is sick of this — she wants to go home. Do you think she’ll get her wish?

“Pretty Little Liars” Halloween episode airs Tuesday, Oct. 22 at 8 p.m ET/PT on ABC Family, right before the series premiere of “Ravenswood” at 9 p.m.
