I predict Doug will come back from the dead, he'll turn evil because he's motivated by revenge and he'll form a group of survivors that he found at a hospital and he'll lead them as they commit atrocities together. During a decisive battle with a group of religious fanatic (but peaceful) survivors, Doug's face is heavily burned and so he covers his entire head in bandages as he continues to hunt down Lee. Doug finally corner's Lee at a derelict room in the hospital and almost kills Lee, but Lee wins because Clem is able to sneak up on Doug from behind and deal a crippling blow so that Lee can finish him off.

Clem later takes Lee back to where they met and Lee dies from his injuries, the end.
