Okay, so I finished season 2 already (yeah, yeah... I had lots of downtime while waiting for shit to render
).
There's one thing that's been bothering me, though. They're all worried about being infected by being bit or scratched... yet they don't say a single word about blood being splattered all over their faces or covering themselves with dead ones (hell, when TDawg had the giant laceration on his arm, he covered it with a dead zombie). Maybe it gets explained in season 3, but I doubt it. And, no, "everyone is infected already" doesn't factor in, as far as I can tell.
