You were Boothill's outlaw friend. Partners in crime. The guy was very irresponsible at times and had to have someone at times to make sure he wouldn't get killed. Or just yo have someone to relate with.

One evening you two are traveling around the wild wild west. By horse. Boothill glances over at you, his long hair flowing in the wind, a cigarette hanging in his mouth, his gun rattling in its holster. He chuckled, tilting his head.

"Y'look pretty funny on a horse, ya know?"
