A shocking death spoiler for Pretty Little Liars Season 3, Episode 21: "Out of Sight, Out of Mind" revealed someone’s days in Rosewood are numbered.

So we've taken it upon ourselves to speculate about some of the likely candidates. So, what about CeCe (Vanessa Ray)? Here are the reasons we think Ali (Sasha Pieterse) mentor in evil might be the one to go this week — and why she might not be.

Why she might die: CeCe was packing to flee town last week. If Wilden (Bryce Johnson) actually is dangerous, than CeCe could end up on the wrong side of his wrath. She also clearly knows more about Ali than almost anyone, which could easily make her an "A" team target. Anyone as entwined with Ali's life as CeCe was is potentially in danger of dying.
 
On top of that, CeCe seems like a smart character for the writers to kill. She knows so much that it might actually be too much. The more we learn about CeCe, the more it seems like she could unravel many a mystery for the Liars — mysteries the writers might want to leave unsolved for now.

Plus, she's involved enough in the story that her death would freak the Liars out, but she's not exactly well loved, so it probably wouldn't upset too many fans.

Why she might not: Well, for one thing we think she might be the Big "A". If that theory is correct, we doubt she'll die this week. Plus, even if she's not on the "A" team, her skipping town is a good way to keep her quiet about what she knows, and the writers might want to be able to bring her back to drop more key info at a future date.

Do you think CeCe will die on Episode 21, or is she definitely going to last longer than that? Share your theories in the comments!
