I read this over at Prison Break Buff and figured I should definitely post it.
When recapping 3.09, Zap2It.com mentioned that when LJ tells Linc that Gretchen killed Sarah — but then tells him he didn’t see it, he closed his eyes, but he heard it. Please, please, please tell me they’re not setting up some sort of bait-and-switch with the head-in-the-box.
Having not seen 3.09 myself yet, I can't really comment on this, however I honestly think they're using this as an opportunity to tease Sara fans.
