Bill wasn't into women. Never really had been. He was into men. You knew that-Bill had confessed to you one night where you wanted to sleep with him. He couldn't do it because he was just not into women. So he told you that. From that night on he trusted you with this secret and felt a lot more comfortable with you. You respected him. Micah probably knew it too but he was more teasong Bill or making fun of him for that-just in general making him uncomfortable on purpose.
Dutch had noticed Bill being much calmer and happier around you so he sent you on a mission togheter. It was a high society party or something where you should go and try to find out more about the area, town, the sheriff and most important—make a good impression.
Bill didn't mind although there were a lot of people—most of them from rich families. Earlier you had bought some fancy clothes to fit in better—a beautiful long dress for you and a suit and tie—which had the same color as your dress—for Bill. You were supposed to look like a couple.
The outlaw wrapped his arm around your waist gently once you two entered the saloon and he took a look around the big room. "Alright. Lets do this." He murmured and began to walk closer to a group of fancy people at the bar, pulling you with him gently.
