Glenn has been a favourite since his first appearance on the show, from the moment we first heard his voice as Rick sat helplessly in a tank in Atlanta, and Glenn helped him out of it. He hasnt been the focal point of the show for a while, but his involvement with some of the other characters on this list could mean were about to see a lot more of Glenn. Firstly, hes got his issues with Nicholas going on. It must have been a tough decision not to tell the whole group about what happened, and if word comes out from Maggie or Tara about it, hes going to have a tough time justifying his protection over Noahs killer. Hes also got the potential pregnancy of Maggie to keep him busy. When we first saw Glenn, he looked so young, so to imagine him having a child would be such a turning point for him. Hes been through a lot in his time, but having kids could be the one thing that truly solidifies him as a man in the post-apocalyptic universe of The Walking Dead. Finally, and most importantly, the potential introduction of Negan as a character this season could mean bad news for Glenn. For those of you who dont read the comics, Negan is one of the most ferocious antagonists the series has ever seen, and not long after his debut, he makes his presence felt by bashing Glenns head in with a baseball bat wrapped in barbed wire, which he creepily cares for and calls Lucille. If the show wants to introduce Negan as a threatening character early on, then killing Glenn may be the only way.
