Vash walked into his old room to find his duffle bag. He hadn't taken it with him because he hadn't needed spare clothes where he was going. He pulled out his trusty pajama bottoms and a short sleeved, black undershirt. He liked Millie a lot, but he didn't want her looking at his scars. The only person he really felt comfortable showing those to was Meryl. The sleeveless shirt would allow her access to the most prominent injuries. He could get Meryl to bandage the other ones tomorrow.
He silently looked over his sleeping brother. Knives didn't deserve to be taken care of. He didn't deserve a bed. He didn't deserve the kindness of the insurance girls. Old animosity stirred in Vash as he forced himself to leave the room.
Once in the bathroom, he quickly locked himself inside. He didn't know what he was running from, but he was, for once, actually glad to be alone. He started the water in the shower and took off his clothes. After the water ran hot, he got in and sat down in the tub with his elbows on his knees and his hands holding up his tired head. He let the water pelt him from above, and he thought about just what he was going to do with Knives...
After about five minutes, he decided he'd wasted enough water and stood up to actually start cleaning off the two weeks worth of sand that had accumulated over his body. He scrubbed himself with soap, taking extra care not to aggravate any open wounds, and looked down at the dirty water swirling around the drain. "Yikes," he said as he laughed at himself for the reaction. He was actually surprised his injuries weren't infected with all that dirt that had been caked in them. Meryl would have killed him if she'd seen this.
Despite the fact that in the last week he had probably saved the entire human population of Gunsmoke, he only allowed himself ten minutes in the shower, and that was twice as long as he usually took. Getting out, he dried off and somehow managed to get dressed without causing too much pain to his injured shoulder. He brushed his teeth for the first time in two weeks (he was so thankful to still have teeth...) and he felt like a completely different person. For just a moment, he felt all his stress away as he went downstairs to have Millie bandage his wounds. He was back with the girls, Knives was under control, and at this moment, he felt free to actually rest.
