I don't believe for one minute, nor could you convince me, that 3R had any input at all into the ending of the TV show - without wanting to put out spoilers. there's no way that the Jon Snow of the books finished up in the same place as the Jon Snow of the TV show - his story (in the show) became a thing of total farce.
We could bounce ideas and/or theories for a long time. But so far we have avoided spoilers. Best leave it with the hope he finishes the books. Soon.
