Nah it was waaaank. The only way it can be saved now is if the wheel chair lad has been warging her the last episode. He did know that was going to happen anyway and did nothing to stop it. Perhaps that's the point of the whole thing. The wee forest people want a mass culling of humans from their Country.
I'd be happy with that ending. I doubt the **** show runners can pull it off though.
But it's quite possible he already had the pieces in place and with his green sight was just a matter of arranging the pieces around the board, ie he knew well in advance Arya was going to kill him at that point and was just luring him in.
Then there's the other angle where the NK is already within the collective consciousness of the 3 Eyed Raven and has overpowered Bran's body and is in control, think 'All of Me'. You'd think the whole touching Bran craic would have played a much bigger role, then again the show writers have been garbage the last 4 years.
