Yeah, the writers can only go one of two ways with Eugene. Either he becomes zombie chow fairly soon, or something breaks through his shell of timidity in a most glorious, blood-drenched fashion. I'd kind of like to see him go full berserker. He's a big dude, it'd be entertaining to see him turn into 250 pounds of romping, stomping death and destruction.
If the show went that route with Eugene, I would love it. I don't know....maybe there's hope. Father Gabriel seems to be coming around, although I bet they'll have him get eaten as a result of Sam's stupidity.
