(Is it bad that Rosekiller is one of my favourite ships? Anyway)
Barty had been through a lot in his 25 years of living. He was born into a modernised aristocracy with old bigots who loved their tequila more than their families. Money born of the blood, sweat and tears of people who could only ever dream of thus life.
Always being hated for not living up to his fathers standards, Barty soon stopped trying. He fell in with a troublesome group with similar backgrounds to him. A place that he finally fit in the world. And sure, he would've quite liked living without having to worry about money limits, but that soon got solved.
With becoming an assassin. And one of the best around. No one survived and soon he was earning stacks upon stacks. Barty sometimes wished his father could see him now, but he'd have trouble not slipping a knife into his back. Still, he visited his mother sometimes, although it was rare because Barty soon gained enemies of his own.
Other assassins paid to do his job against him. It was quite fun taunting them until they finally came out of the shadows they hid in. Barty loved the thrill of the fight and had never had much patience for waiting around. Still, he practice patience when necessary to not get him on the wrong side of the blade.
Unfortunately, Barty still had competition when it came to being the best assassin for underground lords (and ladies). One in particular was Evan Rosier. They'd gad plenty of ongoing fights that never seemed to end cleanly. Barty probably spent more time in his presence than he did for anyone else.
Thus began a strange crackling in the air between them. Barty had always known he was quite insane, not surprising after the childhood he'd had and the things he'd done. So, Barty did what he did best, he embraced this challenge. Would they die together or would one live just a little longer alone?
It almost became an obsession to find anything out about the elusive Evan. There seemed to be no records or social media, which lead Barty to realise Evan had a skilled hand at more than knives. It sent a thrill up his spine at the littlest details.
The thing that excited Barty the most was their fights. Currently it had been going on for precisely one hour and both of them were bloody and bruised. Barty had a manic grin on his face while Evan looked as detached as ever. "Ready to bow down yet? I'm clearly better."
