Vash stays up a bit longer to try and finish the clothes. He would have liked to go into town to trade his labor for more supplies, but he promised Cyril not to leave the twins too often with Knives and he promised Knives not to take the twins into town. So he plans on doing his best to make due with what he has and what Cyril can provide.

It also means that the only interactions Vash will eventually have are the boys, Cyril and his brother. He won't press Cyril for sex when he visits. He's still unsure where he stands with his lover anymore. Knowing something he said or did during his breakdown must have upset Cyril. Was it the breakdown itself? How weak he must have looked during it?

If Cyril also doesn't offer or make hints that he would like to share a bed with Vash? It means that after a couple days the throb of pain Vash always feels will grow into something different.
