AMC'S 'The Walking Dead'
The name attached to that face is Bob Stookey, a character from both The Walking Dead comic book and The Road to Woodbury novel.
“You can see there’s something deeper and darker that’s going on with this character, just from the first episode,” says Gilliard. “We don’t really know what it is. We just know he’s got some issues that he’s dealing with.”
I’d have issues too if I was trying to survive in a zombie apocalypse, but it seems Stookey is indeed “haunted” by his past.
