Ok, how stupid are the people with the governor?
Think about this for a second. Yes, you have a tank, that's majorly cool. It's also extremely powerful. And destructive. Destructive? Yes, destructive.
What in the world is the point of shooting shells at the ******* prison walls? Aren't you idiots going to live there and isn't a secure structure just a wee ******* bit more secure against the living dead than walls that are crumbling or in some cases no longer there because you took Mr. Boomboom and blew them up? Morons.
Enjoyed the show, sad to see Hershel go. Happy the governor is dead. Happy most of the people now following him are dead because frankly they weren't very bright as a group.
