Oh dont get me wrong, I thought the episode was terrible and agree with you on why it was terrible. But I still think they killed him b/c of my Mel-show theory so I think hes also gonna face some bad thinsg in the books. (Add to that his failure at the Blackwater b/c no mel, and I think hes gonna fail here b/c no mel)
That said, he'd be a great commander of the nights watch. That'd be really interesting, almost moreso than Jon.
