Well after watching tonight's episode, (spoiler warning) I'm wondering how Randall and Shane re-animated after their death since they didn't get scratched or bitten.
Thats the next big turning point for the series and those viewers like me who have not read the graphic novels dont have an answer. There is 1 episode left before the season ends and lots of walkers on the way. It basically means anyone who hasnt died with a shot through the head can come back now for some reason so there brings all sorts of trouble and im intrigued as it brings a totally new direction for the show.
