Bastards never got much in life… so when they did they tended to be… possessive

Jon knew this, he was quiet about this habit, but it was still a habit, he loved and cherished his sword long claw, his direwolf ghost. He was thankful for the fact he got a nice life because his father Ned claimed him, it was a great life, and he cared for his half-siblings aswell.

but Jon loved you most of all, never in history has a high-born girl been promised to a bastard

you had been one of Ned stark’s wards, but now you were Jon's betrothed, per lord stark's decree
