The Walking Dead is back and it ain't messin' around!

Is anyone else loving this season of The Walking Dead as much as I am? The first episode was a little slow, understandably. They had to explain what has been going on for the last 6 or 7 months. But the second episode? Holy captain crunch. Let's just kill 1/3 of all the inhabitants of the prison. What a great idea! Too many characters to keep up with anyway. Now let's get to the questions. I have OH SO MANY questions.

Who was feeding the rats to the zombies?
The obvious choice would be Lizzie, the crazy child that likes to name the zombies. But could she really reach that high and make it out at night all by herself and her sister not find out? I just feel like it is way too obvious if it turns out to be her. But who else could it be? Carol?!?! She is kinda nutso nowadays. I have no idea on this one.

Who burnt Karen & David?
So many choices on this one. Where to begin? Maybe it's Carl?!? Rick gives him back his gun and now he is all crazypants again? Or WAIT FOR IT... Maybe it was Rick?!?!? The look on his face when he had to kill those pigs. That moment he knew that he could no longer just be Mr. Farmer. That he had to go back to making the HARD choices. He snapped. And now he's back to badass Rick. And he knew, for the protection of all, that those that might be infected needed to die. But I am going to go out on a limb here and say that it is Beth or Roy. Ya know, the former Army medic, closeted alcoholic that made the shelf fall last week on their trip to the Big Spot store. Why is it him? He is a former medic. He might be a little skittish about sickness. So he got rid of the infected before they could infect anyone else. Why could it be Beth? Because she crazy. She straight up freaks me out. Crazy. It could be anyone. But I draw the line at Herschel. I love me some Herschel.

Did Michonne lose a child?
When Beth had the conversation with Michonne about kids losing parents being orphans and spouses losing spouses being widows, but that parents losing kids was so horrible that it had no name, you could see that it bothered Michonne. And then when she was so adamant about not holding Judith, but then she did and she broke down. There has to be a backstory there. But what is it?!?

Where is The Governor?
Michonne seems to be the only that cares. But of course, she wants to have her revenge for Andrea. But really, where the hell is that crazy, one-eyed psychopath? I need to know what he is up to. NOW. You just know he is cooking up some crazy plot to get back at those in the camp. Maybe he is the reason that all of the zombies seem to be congregating around the prison?!??

I CANNOT wait to find out. What about you? Any theories?
