I wouldn't hold out too much hope for Carl "snuffing it".
And therein lies the problem with having kids in a prominent role. You know they're never going to get axed.
Usually, I would agree with you, but in the comics, Carl has a very important role to play, so I'm letting it slide here to see if it comes to fruition.
I agree also with the points made earlier about Shane just being a big bitch... If redneck boy can get over his racial predispositions, Shane can accept the fact that he's gonna be second fiddle...
