Also, so many people want to see Jon on the Iron Throne, but this is probably exactly why it’ll never happen — at least some fans are totally convinced of this. But since he’s one of the most important characters, he has to do something really important.

Taking into account his long-term obsession with White Walkers, fans suggest that he will be the one who’ll save everyone from them... and may even do more than that. Clearly speaking, he will sacrifice himself and will become The Night King, walk them away from Westeros, and will guard the White Walkers eternally to keep them away from the living.
