Great episode, I thought. They had a great Talking Dead afterwards too. Lauren Cohen got a little choked up talking about Hershel leaving.
As far as Carol, I think she's coming back...and this is how it's going to happen. Tyrese was going to be dead to rights in the prison fight. He's saved by who? Carol's little protege, whom she trained. So, she saves Tyrese's life. When Rick talks to Tyrese finally about booting Carol, Tyrese is pissed...but has second thoughts because it was Carol's "little girl" so to speak that saved his life. So, that should nip that one in the bud.
Next villian, I'm not too sure. I haven't read the comic books yet or anything, I do have a buddy that has them all though. Obviously the first order of business will be securing a new place to live which will bring it's own confrontations and hardships, probably a few more deaths, or maybe none. The group is so experienced with walkers now, they could probably clear out a place like the prison again with little trouble. Downside is they're low on supplies since they left in a rush.
I think Judith, Rick's daughter, is alive. The blood and the reaction was a decoy I think. Then again, I doubt they would show a little baby getting eaten by walkers...watching a girl like Meghan getting eaten is pretty hard to watch as it is.
I thought it was interesting that Kirkman said on Talking Dead that in the comics the Governor got a much less satisfying death. Something about wanting to leave the reader wanting more. I'm glad he went with a 3 person job. It was cool that Rick started it, Michonne dealt the mortal blow, and Lilly finished the job. It went about as well as it could have gone really, lots of closure.
I STILL think that the little girl, Carol's protege, is the one that really burned the bodies and Carol covered for her. I think she was the one that was feeding the rats to the walkers through the fence.
