I kind of felt bad for the hitchiker too. I agree tho, that they sort of have a new stance, so to speak, and don't quite trust anyone.
Btw, they synopsis for tonight's episode in the tv guide:
"Arrow on the Doorpost" - Rick & the Governor contemplate a peace treaty.
Hmmm Don't trust the Governor Rick.

Can't wait to see it. I got my daughter hooked too. She's dying to see the first two seasons.
