I thought it was odd that they sort of just gave up on finding Merle, especially his brother. One thing I missed is what happened to Jim. He wasn't with them when they got to the CDC. I know he was bitten and got the fever, but did he die on his own? Did they kill him?? Poor Jim, I really liked him even though he had such a small part. The actor who played him did such a great job when Jim was discovered to have been bitten, when he kept saying "I'm ok i'm ok". And why did the CDC doctor whisper in Rick's ear?
