See, this is interesting. Early last season, I wrote the show off, and my wife was just getting into it, which eventually brought me back into it. I've always thought the total disregard in being splattered with zombie guts was a HUGE mistake, and just down right dumb. I still have a serious problem with that aspect of it, along with someone doing something completely illogical in EVERY frikken episode, thus putting themselves, and everyone around them in extreme danger, but hey, it's no dumber than Gilligans Island, and I know every line of every episode of that show.
..but now we know that everyone is already infected, so the zombie guts thing is a moot point.
