He ran through the woods, careless and free, if for just a short while– shot at poorly made targets he had set up weeks prior with an even shittier bow, missed half his shots, but in his mind he was the best. For just a moment, he imagined that he lived on his own, that all he needed was himself. That no one could cross him and his bow. If anyone ever saw him, they'd be struck by just how skilled of a shot he was.

And for how much of a jerk he could be at times to his siblings, Fin treated him with a weird amount of respect. I mean, they didn't tolerate his bullshit, but there was always a certain softness to the way they referred to him. He could never quite place why, and it's not like they got along particularly well. He wasn't one to get along with most, actually. But he never sat on the thought for too long.
