First of all, if you disagree with me, then please don't reply.
OK, what I was thinking Is that maybe, just maybe, Kenny might be alive. What I think happened is Kenny stumbled when he got out of sight, and a zombie jumped on him. Kenny managed to push him off, and he got covered with the zombie blood goo stuff. So maybe he could've gotten away by running, and the zombies ignored him? It could be possible, but highly unlikely.
Again, if you disagree or just plain want to say something along the lines of, "Get over it, he's dead." Then don't bother to reply.
