i feel like I'm about to nail this prediction. I have no knowledge of the comics... i mean i know there's a fukked up dude named the Governor about to come on the show, but i dont know anything else.
I bet you T-Dog has at least one friend in the joint. I say this because they've kinda handled him as a token black and don't really care if it's mildly offensive, so why not have the black dude's "boy" meet up with him in jail?
Also, I think he lives b/c everyone expects him to die at some point. Have we even gotten an ounce of backtory on T-Dog?
Same goes for Mickey Doyle on Boardwalk. Dude should die every week, but manages to escape by the skin of his teeth.
