If there's one thing we know about Pretty Little Liars, it's that we have to expect the unexpected. Twists are around every corner, and to stay ahead of the writers, fans are forced to come up with as many extreme, out-of-the-box theories possible. Fortunately, the Pretty Little Liars fandom is more than up to the task, so each week, we like to dive into the wilds of Tumblr and pick out an intriguing theory to explore.

This week, we want to talk about a theory that we've seen put forth by a lot of fans: that Alison's (Sasha Pieterse) story about being buried alive was a total lie.

Why are fans starting to wonder if that story is a fake? Here are some of the reasons we like this theory.


1. Ali's story vs. Melissa's story. Melissa's (Torrey DeVitto) story about burying Bethany Young alive doesn't seem to quite match up with the timeline Ali laid out for that night in the Season 4 finale. According to Ali, there was a decent amount of time between when she and Spencer fought and when she was later hit over the head and buried, but Melissa's account made it seem like she found the body shortly after the fight. This could just be because Melissa's version of the story wasn't well articulated, and she actually found the body much later in the night, but maybe not. Maybe there's a reason the two stories don't match up — because Ali's is a lie.

2. Seriously, two people were buried alive?! Even leaving the timeline wonkiness aside, if both Melissa and Ali are telling the truth, that means two different people were buried alive that night. Impossible? No. But highly improbable, even for Rosewood.

3. Who's more likely to lie: Melissa or Ali? Obviously, it's also possible that Melissa is the one who's lying, not Ali. But at this point, it certainly seems like Ali is the one with more motive to lie. Plus, we know she's willing to totally make up stories (kidnapping, anyone?), and she didn't tell the whole truth about that night to the Liars during the Season 4 finale, since she left out her meeting with Garrett and Jenna.

4. The Grunwald thing. If this theory is true, it would mean Grunwald lied to the Liars about saving Ali, and we're not really sure why she would do that. In that way, Grunwald is a strike against this theory. On the other hand, if Grunwald's story about sensing Ali's distress is a lie, it would get rid of the annoying intrusion of the supernatural into the otherwise non-fantasy Pretty Little Liars plot. Keep that stuff in Ravenswood where it belongs!

What do you think of this theory — is it possible, or totally crazy? Sound off in the comments below.
