It's not just Shane. This show tends to kill off the characters that actually bring believability and humanity to their parts. Minor cogs like Oscar and Lynerd Skynerd were both vital, yet deemed expendable because their names are not in the opening credits. Carole still is listed as a guest star, and to me, she is as crucial as Darryl. In fact, they risk killing a LOT of the good things about Darryl when they eventually send her off the show. There was SOOOOOO much story left to explore with Merle. But the writers have no clue. They don't fill the space inbetween the major beats. This show has got to have the emptiest average of plot per episode. On a pie chart it would not register.
