Yeah, I wonder what the story is with the aquariums??? Nasty. The gov'nor is one messed up guy.
I was wondering about the aquariums too, I mean why 'collect' the Helo survivor head at all. He used him to get to the supplies after that why keep his head. It seemed like the Governor had some kind of personal hate for him, even though he didn't know the guy.
The other thing that was interesting was how Merle reacted towards the Governor when he asked him if he thought he was still out on the school yard. During the scene where Merle was pissed off at the scientist for saying something about him. He had the look of fear in him, as if making the Governor mad is not something one should do.
