My theory on this is that Wildfire is mutating in such a way that it contaminates mammals besides human beings and eating infected meat is kind of like getting bit. In that the more or less dormant contagion suddenly gets ramped up, kills you and makes you a walker. If that's the case, then it's only a matter of time before everybody and everything is a walker and that.... well, that makes for a bad ecosystem for whatever type of microorganism Wildfire is.

So maybe that theory sucks. MAYBE THEY ALL HAVE EBOLA NOW. EBOLA ZOMBIES.

I agree with Amanda, though, I like that there's a little levity. Some people SMILED in this episode. Full-on smiled. RICK SMILED AND IS NO LONGER DEAD INSIDE YAY.
