There were several key characters missing in action on the Pretty Little Liars Season 3 summer finale (Season 3, Episode 12: “The Lady Killer”), and we’re dying to see some of them return in the Halloween episode (Season 3, Episode 13: “This Is a Dark Ride,” airing October 23). But if you had to pick one, which character’s sudden return would be the most exciting?

The first missing person is Jason (Drew Van Acker), who disappeared from Rosewood after driving drunk and hitting a parked car. Spencer (Troian Bellisario) helped her half-brother by driving him and his damaged car back to her house, and Toby (Keegan Allen) wound up taking the blame. But that was the last time we saw Jason, and we have no idea where he’s been hiding out.

Then there’s Melissa (Torrey DeVitto). She dropped out of the mix early in the season, after confessing that she’d been faking her pregnancy for a long time, even going so far as to fake her miscarriage at the last minute. She also revealed that she’d been threatened by an anonymous person who forced her to wear the Black Swan costume to the masquerade ball and keep Jenna (Tammin Sursok) distracted. But then Melissa went back to Philadelphia, and we haven’t seen her since.

And where has Lucas (Brendan Robinson) been? After acting really suspicious around Aria (Lucy Hale) during Jenna’s birthday party, Lucas hasn’t been heard from since the Liars found pills in his photo bag. (He’d been working in the same photo studio the Liars spotted him in front of “that night.”) Those pills were the same ones used to drug Emily, so he’s obviously an “A” suspect.

Who would you want to reappear the most out of these three mysterious characters?
