The scene we saw at the end of the episode was Carl lying there either scratched or bitten, so im not sure how he can survive.We saw it in season 3 when Hershel was bitten and his lower leg was immediately chopped off and he managed to survive. But with Carl they can't exactly cut his stomach out.

I pretty sure he's going to die in the opening episode of the next season. They will give him a good send off and dedicate the whole episode to him. It won't be such a great loss him dying as i thought it would. I always thought he would have been untouchable earlier on in the series. But he has grown up and hardly featured in the last two seasons.

Not sure how Rick can come back from this.This may be the start of his downfall. Not sure how many seasons this show will end up having but i don't think Rick will survive till the end..
