The Pretty Little Liars cast and crew is preparing to film the highly anticipated Halloween episode (Season 3, Episode 13: “This Is a Dark Ride”) next week and new details are trickling in about who will be featured in the episode. (Aside from pop superstar Adam Lambert, that is.)

So, which girl will definitely be making an appearance in the episode?

Alison DiLaurentis (Sasha Pieterse)! Showrunner Marlene King revealed on Twitter that Ali will be featured in the episode.

We already know that the episode won’t be a flashback episode (like last year’s episode) so we wonder how Ali will be featured. Will she be in a flashback or is there an upcoming twist coming up about Ali being alive? We’ve seen some hints about Ali (or possibly her twin — who appeared in the books but hasn’t come up on the show yet) being alive. Could this mean that episodes featuring a non-flashback Ali are coming up?

We know: we are just wildly speculating. But hey, it’s fun to think about!

We’ll have to wait until October to find out what really happens with Ali.
