ok this is definitely a bit spoilery

 


At the end of the books, what prompts the Nights Watch to murder Jon Snow is that Jon Snow decides to use the Nights Watch to march on Winterfell, both to liberate it and save Stannis and his sister, thanks to a provocative letter from Ramses Bolton claiming to have them both and demanding the return of recently escaped Reek for their safety yada yada.

Apparently they are filming The Sacking of Winterfell right now and very much in the thick of things is... Jon Snow.

So all the talk about how he likely gets resurrected and returns to life free of his vows to the Nights Watch are apparently on point.
