We know Ali's fate will be revealed during the Season 4 summer finale — Is she alive? Is she Red Coat? Is she dead? Does she have a twin?! — and this exclusive behind-the-scenes pic, courtesy of director Norman Buckley, from Season 4, Episode 15 ("Love ShAck, Baby!") makes us ever more eager for the truth.

In it, Sasha Pieterse (Ali) is casually sitting in what looks like Ali's room. Could this be a flashback? Seems likely. But how cool would it be if Ali actually was alive all this time? Of course, if that were the case, she'd probably have to spend a few months in Radley before being set free to strike terror on the teens in Rosewood. After all, you'd have to be pretty crazy to fake your own death. Of course, it doesn't have to be Ali either. For all we know, this could be her much talked about (but highly unlikely) twin, Courtney. 

Looks like we'll have to hold tight until the summer finale (on August 27, 2013) to shed some light on the mysteries surrounding Ali's disappearance. But for now, we have this behind-the-scenes pic to analyze. So let's get sleuthing, PLL fans!

What do you think of this behind-the-scenes pic? Are you happy to see Ali again? Do you want Ali to be alive after all? Sound off in the comments!
