Have people figured out the no bite marks thing?
IGN Comics: First and foremost: great episode! This is the first time that we've seen hard evidence of the dead coming back to life without being bitten, which is something established in the comics. In Season 1, we saw Jenner studying the disease extensively. So is this something that he might have missed, is withholding, or is it a completely new development in the zombie plague?
Robert Kirkman: I've stated many times that what Jenner whispered [to Rick] is something that we'll be revealing this season. You'll know what he said by the end of this season. We've just watched the next-to-last episode of this season, and we still haven't seen that reveal, but I will say that this scene – where Shane gets stabbed and comes back as a zombie without having been bitten – is definitely something that is going to inform that reveal coming up in the next episode.
