Blood brother? Oh my no. He raised me as his son, though it was a millennium before I discovered that he was not my father, but rather had found me as a babe, apparently abandoned by true parents after Odin and the forces of Asgard had defeated them in war. Though I admit I am more surprised that a version of me is married. I assure you I have never been in such a committed of relationships.

[Though that piece of information gives him a bit of hope that he is capable of such things.]
