WHY WE'RE WORRIED: Though he’s survived countless walker attacks, the Governor, Terminus and then some, his luck’s gotta run out sometime. Or does it?
WHAT HE COULD DO TO PROTECT HIMSELF: Stop making boneheaded decisions. For instance, if a guy — not mentioning any names (Nicholas!) — tries to kill you, put. His. Ass. Down.
LIKELIHOOD OF DEMISE: It would be just like The Walking Dead to let Glenn live through the season finale, only to kill him in the subsequent season’s premiere. But portrayer Steven Yeun’s appearance at Comic-Con suggests that he’s safe. Well, safe-ish.
