Question: what is the blood relation between jon snow and daenerys targaryen?
Answer: In the final moments of the episode, Jon told Daenerys that he is the son of Dany's brother, Rhaegar Targaryen, and therefore her nephew. Daenerys, rather than balking at the fact that she was sleeping with her relative, immediately questioned the veracity of the information. “Bran. He saw it,” says Jon.
