I knew that walker was going to follow Carl back to the farm, and once we saw Dale wandering around in the dark, I knew he was going to run into it. I can't say I predicted his death, but once the thing jumped him, I realized that this was not going to be one of those times a character gets saved at the last minute. Between the fact that Andrea still hadn't told him they were sparing Randall, and that he'd actually stated he didn't want to live in their world, it was much more compelling to kill him off from a dramatic standpoint. I half expected him to just give up and let the thing bite him. Although I was really hoping Andrea would tell him about Randall before he died.
I've gotta say, though, that if I lived on that farm, I would never go wandering around in the dark by myself. There's a reason someone has to sit on that RV with a rifle.
Anyway, I liked Dale and I don't want to see him go. Sure he whined a lot, but that's because too many people were doing the cold-blooded thing instead of the human thing. Rick may be the moral compass for the group, but he was getting too off-center. Dale was Rick's moral compass.
Yes, Carl is turning into a little bastard. I guess Rick may have stopped his own slide down the slippery slope when he realized what kind of child he's going to be raising.
