Game of Thrones Season 6 Episode 03 Oathbreaker
After awakening, Jon Snow is greeted by Ser Davos and Melisandre. Melisandre tells Jon that her religion prophesies a “prince that was promised” and suggests that this prince may not be Stannis, as she first thought, but Jon.
DAVOS: What do you remember?
JON: They stabbed me. Olly… he put a knife in my heart. I shouldn’t be here.
DAVOS: The lady brought you back.
MELISANDRE: Afterwards, after they stabbed you, after you died, where did you go? What did you see?
JON: Nothing. There was nothing at all.
MELISANDRE: The Lord let you come back for a reason. Stannis was not the prince who was promised, but someone has to be.
