It seems the only way the writers can extract any emotional impact out of these characters is by killing them off, or having them injured horribly. We'll have a whole new cast by the end of the season.
Congratulations to the oozing pile of devoured flesh + bodily fluids formerly known as T-Dog! You never have to deal with those pukes you've deferred your screen time to over the past few seasons. You are in a better place now, and free to pursue a much better show. Only problem is your death now precludes the spin-off I'd been conceiving around you called T-Doggtopus vs. Zombisaraus. Oh well. Back to the drawing board.
