In this new promo for the Pretty Little Liars Halloween episode (Season 3, Episode 13: “This Is a Dark Ride”, airing October 23), we get a better feel for the setting of the Halloween party the Liars attend. Yes, it’s on a train, but we didn’t realize it would be in motion the entire time.

We also get a peek at Aria’s (Lucy Hale) costume, which is of Daisy from The Great Gatsby, and Hanna (Ashley Benson) has a major Marilyn moment. We see that scary baby monster mask from last year’s Halloween episode, which we know will make appearances in Pretty Dirty Secrets as well.

Who do you think ties Aria up with duct tape? And guess who Emily is kissing? Check out the promo below and share your theories!
