I thought last night's ep should have been a twist where everyone dies and jon somehow usurps the night king because he's already half dead or some shit and the rest of the season is him leading the army of the dead to kill cersi and all the other living. It would have really pissed everyone off even more and nobody would have seen it coming. Then everyone could argue about whether or not the whole thing was a metaphor for replacement migration. Instead they went with hackneyed and predictable. Cowards.
