Not a whole lot to say, really.
Rick seems to be less unhinged than he was, though it's impossible to tell how close to return super-Rick from the start of the series is.
Right on cue, Tyreese and co. have re-appeared and joined the Woodbury crew. The two kids are predictably all for joining up with the Governor to attack the prison, but Tyreese also seems to want to help - he's offering the prison layout, and he's sure to mention the breached wall they entered through. However, he's mentioned that the people (other than Rick) seem decent. Will he have a change of heart when he inevitably learns that the Governor wants them all dead?
Merle seems harmless, and he's integrating well with the group.
Michonne had lines! OMG, she can speak. Saying that, she still seems like a useless extra ripe for bullet/Walker fodder.
Glen is still angry, but I get the impression that he's less interested in his one-man Glengeance show now that the whole group has been attacked.
Talking about the group, the attack seems to have scared them straight, and they're slowly returning to being a disciplined killing unit (the addition of Merle seems to help - has he taken T-Dogs place, I wonder). The group dynamic is definitely mirroring Rick's mental state.
Blandrea... deary me. Stuck between two worlds, unsure who to believe. My money is on Andrea being the next character from the group to go (though I expect the next human death will be that kid with asthma - why else build the character up?).
