Ahhh but in the flashback to when Leaf pierced him with Dragonglass to create a WW out of man, ironically to protect The Children of The Forest from the men, he was just an ordinary looking bloke. No traces of blonde Targaryen hair (yes, I know Jon is dark but he is mixed bloodline) on display. I still think he is a random Stark from a 1000 years earlier.I’m still hoping there is explanation to come for all this Night King and Bran weirdness. My own theory for some time has been that the NK is a Targaryen which would explain why he didn’t burn.
