Wow, that was a hell of an episode. I definitely did not expect the ending. I can definitely understand why Rick sent her off, she overacted to a situation that they barely understood at that point, and then continued to act recklessly. As for what she did, I can understand the thought process that lead to it, but I don't agree with it. At that point the sickness had barely started to infect that prison, and they didn't really know exactly how it was going to behave on a regular basis. Just because one person dies doesn't mean it's going to kill everybody who gets it, in the right situations the flu can kill, that doesn't mean if I get the flu tomorrow I'm going to be dead by the end of the week. Now, what she did might have been necessary eventually, I just think she should have waited until she had more information. They were isolated, and weren't an immediate thread. I was wondering if perhaps her leaving was actually the set up for the spin-off. Maybe it could follow Carol in the Rick role in a new group.
