He's a bounty hunter. He's into DnD. He somehow doesn't know about cosplay or how to improv despite this. He CAN dance. He fell for the Doctor so hard the only coherent thought in his head under stress was proposing to them. Within the hour he'd kissed them, sacrificed himself, and said "find me" after making them catch a goddamn marriage bouquet. He's a nerd. He's socially awkward. He listens to Kylie Minogue. He's a sweetheart. He's a Killer. He's engaged to the Doctor. He is the moment. He is the Rogue.
