The only one of these that is actually surprising for me, weirdly enough, is Jenner's. Looking at the characters, the ways in which they died and their roles on the show, it is unsurprising that they died. Half of these characters were only on one episode and had no true linkage to the group. Those who were really tied to the group and on for more than a few episodes (Sophia, Lori, T-Dog, Shane and Dale) died for reasons that serve to push the plot forward.

Considering Jenner was closer than most (maybe even anyone) in figuring out what was going on, it is kind of surprising that he didn't want to work more in figuring it out (although I guess his lab was about to blow up so it's not terribly surprising).

I miss my bb Shane.
