P.S. Did you catch their conversation about the 2 dead security guards? No bites, apparently they turned from just scratches. Interesting! Might be important to know later on - I laughed thinking about all the hand to hand combat Rick and Shane had with walkers in this episode, yet not a single scratch! Love it!
More importantly, all the times people have gotten covered in walked blood, when they have open wounds of their own, and somehow, no transmission.
