I have to ask this. The entire group took Herschel waking up as a good sign. Does that necessarily ensure recovery? I mean, it's great that he hasn't turned yet. Still, he lost an awful lot of blood and there's a high risk of infection.
Also, as harsh as it sounds, giving CPR to someone seems like a really risky thing to do on that show. If it doesn't work, then the person just turns and eats the CPR giver.
Why do I always do this to myself???
