Awesome episode tonight!
And that last scene! Carol! So my theory is that Noah ends up running into Daryl and Carol (together, they fight crime! And walkers!), and then Carol gets herself "saved" by the hospital people in order to help Beth from the inside while Daryl and Noah go back to the church to get more help - Noah must be who Daryl had with him at the end of last week's episode who we didn't see.
I even liked Beth in this episode, when I really haven't had many feelings about her before. And I really like Noah, too. Some definite cuteness between those two, as well.
Unfortunately, it looks like we might not find out what happens next week because the preview was all Abraham's group. Not that I don't love them, too, but I want to find out what happens!
