DeNiro, I was wondering about the pig and the Harry Potter kid too. I didn't see the kid get bitten/scratched. How did he turn. I'm only speculating here, but maybe pig was infected (somehow?) and maybe other food? Thus, Potter ate it and turned.

This could lead to a storyline where the group tries to determine who ate what and who will turn?

Remember there was at least one comment about how nice it was to have good food?
I like Darryl too. He & Rick are probably my favorites, tho Michonne is pretty good kicking ass. I still maintain that the show is filled with really good actors.
Yea Mig, Herschel's daughter (Beth?) seems to have gotten very nonchalant about people dying. Kind of immune to it.
TIS
I forgot about the water? Could be!
