Spoiler: showI did think they were going to bring it back to the game a little more, with Frank's friendlier, more whimsical nature getting him into trouble, getting bit, killing himself, maybe after a fight with the paranoid antisocial Bill, instead of the degenerative disease / zombie-apocalypse-agnostic story they did
also I'm a little bummed we don't get to see Bill kick some ass with a machete like in the game
