He thanked Daryl for the deer meat. And they kept showing the water. And Rick kept looking at the zombie with the bleeding eyes. Maybe at some point in the dying process, these zombies start to bleed... then they infect the dirt with blood, which is eaten by animals, which in turn have toxic meat that can make some people sick?
I thought, in the opening scene, it looked a little gros, rick just washing his face in an open barrel of sitting water. So that must be the THIRD major theme they were going to enter this year. ZOmbies + Evil men + dont' drink the water...
