Now that the clear voice of reason is gone, what now?

T-Dog (IronE Singleton) will pick up where Dale left off. He has a big mouth and likes to talk a lot. Oh wait, is he even on the show? Seriously, why is he even on the show? The writers have done absolutely NOTHING with him. I feel bad for IronE. Think about it, lesser characters get more screen time than he does who is considered part of the original cast. Either write something substantial for him or kill him off, but just don't have him standing in the background every single episode.
