wasn't Jenner the scientist in the Biological Control place that blew up at end of season 1. I don't remember his whispering something into Rick's ear. Will be interesting to see what is revealed about new infection spread, probably not till next season though, i'm guessing end of this season will just be surviving the oncoming horde from end of this episode....which look soooooo cool!
btw, thought it was interesting the use of 'zombies eating' shots to show Shane transitioning into zombie, like they were eating his mind and that was turning him.
Guy who played Shane was awesome, didn't like character and that came down to the guy playing him very well. Hated character and yet when he comes up to Rick to tell him about the son and saying he needs his dad and Rick was prioritising mission over son, you couldn't help but agree with Shane. That is the sign of a well played out character, hate him but still agree with him and like him sometimes.
