Well, Jon, I have some good news and some bad news.
The good news is, you’re not actually a bastard. Sure, we’ve known this for a few weeks now, since Gilly confirmed that Jon’s parents, Rhaegar Targaryen and Lyanna Stark — we’ve known that for even longer — were married when she had him. But legitimacy will no doubt be some sort of relief to a man whose fine features have borne the strain of second-class status from the beginning of this story.
The bad news? Say hi to your aunt.
