Hmmm, despite being well-trailed and also resolving the issue of where Robb's story was going the actual scenes of the Red Wedding were genuinely shocking.
There was something sadistic in the ordering of who was killed in front of who. Caitlin's pleading for Robb's life was poignant and a great final scene.
But having Arya witness the death of her remaining family on the brink of their reunion tipped over in melodrama of a particularly grotesque kind.
