The Walking Dead: Betcha Rick Can't Guess What's Behind the Door...

In a new TV spot promoting the third season of AMC's The Walking Dead, which will come to TV beginning October 14, Rick Grimes is anticipating what's behind a door. In a quick TV spot that doesn't give the answer, it seems most likely that he's about to be faced with one or more walkers--but then again, the room he's in looks a bit like something out of the prison but not necessarily like a cell. Could this be his first look at the prison armory, an important component in keeping the building relatively safe for most of the season?
