I don't think carol killed Karen and David, I think she was covering for that little girl lizzie, the one who couldn't stab her father in the head. the way she asked for the girls to come with her when rick banished her, or the way she was not really trying to defend herself from rick banishing her. I'm pretty sure its that same girl that was feeding the rats to the walkers on the outside of the fence too.



there is one thing that is bugging me. they have gasoline, or hell the zombies have clothes on even..instead of wasting energy stabbing zombie heads with crowbars and what not in shifts, why dont they just lead them all to one spot and set them on fire?

just seems like that would be more efficient and give them a little breathing room inbetween mass killings.
