If he was going to kill this person, he'd probably have done so already, so clearly it's fine! There is a bit of a small frown when a nice comfy stock crewmember mattress isn't taken in favor of just a spot on the floor, but if someone's really tired that's surely plenty good enough. And besides, he'd made a giant bed heap with the rest..

Patiently, he waits and does absolutely NOTHING for a while, eyes fixed on the sleeping form before very slowly .. untying his boots with one normal looking hand and one very much NOT normal looking hand and kicking them off with a sigh. Ah, foot circulation, that's the true essence of relaxation. And then sets out to do a few things, now on quiet besocked feet.

There's no interruption at all - Vash may well get to sleep right to sunset! But when he wakes, no matter how short or long that takes, there's a bottle sitting nearby, with a plate and a wrapped sandwich sitting on it. The bottle's ... seriously watered down ale of some form, but liquid and not blisteringly hot so probably better than nothing.

The sandwich looks a fair bit fresher.
