Wow, Maybe Rick's group will be on the verge of being thrown out when the W''s show up and they save the day?
There was a scene on the Talking Dead showing Carol threatening the Dr. next week. Holding a knife to his throat and telling him she could kill him. She is a bad ass.
I thought the same thing. I was wondering if they came up with the challenge and then selected them because it would make a good story that she got her start there.
