Forget candy and costumes. The best part of this year's Halloween will be the return of Pretty Little Liars, as this ABC Family favorite airs a special flashback episode next Wednesday night.

We've already given readers a look at what the girls will be wearing on October 19, and now we've got a pair of clips from the episode, which is titled "The First Secret." In the first, Jenna actually has her sight... and then she has her first encounter with Alison.*

* I am interviewing Sasha Pieterse later today. Send in any questions you have for the actress and return to TV Fanatic later in the week for the exclusive Q&A!
