Jon probably would have told someone that he killed Dany, since he's got the honour of Ned that also got him killed.
But yea, when the Unsullied sailed off, and Jon, Arya, Sansa and Bran were saying goodbye, couldn't Bran have just been like, "alright brah, you're pardoned."
I mean FFS Snow saved everyone from more mass murderings.
But I guess he can stay King beyond the Wall. He was always most comfortable there.
I don't mind the ending. But I very much minded how they got there.
