I wish that after hearing what they did about Michonne and Andrea from Merle there would have been a conversation between the group and her! I find it unbelievable that they heard all that and then apparently didn't inquire for any more details. Maybe ask her about why she kept two pets? How she met up with Andrea? Stuff like that. I'm getting the feeling that they group is accepting her, heck Glenn trusts her enough to want to go to Woodbury with her watching his back...but I can't help but ask: why? Why do you trust her? Have there been some bonding moments we haven't seen?
I do think she made a step in the right direction this episode though. At least she helped Hershel out, and obviously picked a side.
What exactly was she doing out by that bus all day, anyway? Keeping watch? Or is she just so uncomfortable within the walls of the prison that she prefers to lounge outside?
To me, her hanging out by the bus is a compromise for Rick's sake. He doesn't even want her around at all, and after the little Lori-sighting in the previous episode, she may just figure it's safer outside. So, she hangs out there and waits to earn their trust, or something.
Emphasis on "or something."
