Jon Snow is a Stark and a Targaryen. I figure the two at least get into combat with each other. Jon , already being ‘undead’ means the night King has no power over his dead body.

Was it the Night King who resurrected Jon? Or was it the three-eyed raven?

Has the night King or the three-eyed raven been the Lord of Light all these years?

"Jon , already being ‘undead’ means the night King has no power over his dead body. "

First time I've seen that theory. I like it!
