Well looks like the prison is about as safe as, well, a prison in this new promo for Season 4 of The Walking Dead. Along with series regulars, we also get a glimpse of a new character being introduced in Season 4, former army medic Bob Stookey, played by Larry Gilliard, Jr. Also from the looks of things, it seems like Walkers are going to once again be a major threat, along with the more mundane Governor and a threat from within. I'm looking forward to Season 4, especially since Breaking Bad just ended and my Sunday nights are free. What about you?
