Back From the Dead: The Most Shocking Resurrections From the 2011-2012 TV Season

We all knew it was coming — at least, those of us who have read the comic book version. Yet Shane’s (John Bernthal) death in the penultimate episode of Season 2 of The Walking Dead yields a big reveal that we got hints about in Season 1. After Rick stabs and kills Shane, Shane comes back as a zombie — despite the fact that Shane's never been bitten! Rick (Andrew Lincoln) must now confront the fact that he just killed his best friend twice and that all of the survivors in his group have been infected and will turn into zombies when they die.
