first thing I thought when Rick cut himself to attract the zombie then stabbed it was "zombie aids". I mean, in the first season, when Rick and Glen were getting disguised as walkers, there's mention of "don't get any blood on your skin", which certainly seems like a good idea, even if just as a precaution.
I remember someone, I forgot who, said the prison was going to happen at the end of this season but not sure if that was only rumored but that was when Daranbont was in charge, so who knows now.
I'm enjoying the nice little tie-in's with the comic, I think they are working toward finding out that you don't have to be bit to be infected with Shane was talking about how military were shooting PEOPLE down that were not even walkers... And also when the dead cops were infected but not even bit, then Shane using the same knife to cut himself, that we assume he used to stab a walker even though that scene was skipped, maybe on purpose so we could forget it easily and it adds the shock factor for if he were to get infected..
Is it true Jon Bernthal is signed to do a pilot for another show?
Shane could definitely end up getting infected as a result of this episode, Rick too. I don't think it's likely though.
