Levi's method of dealing with the crystal has also been to demand his shit back, rather than ask nicely, but he also doesn't care how other people use it. If they want to ask for things that makes them happier or their life easier while in this strange place, let them.

"Suppose if you have things to do it for you, you'd never have a reason to learn." He can concede that much, at least. Levi can throw together a handful of things if pressed - porridge, stew, things like that. But even he doesn't really count what he does as cooking, necessarily. Perhaps he could if he wanted, but that seems to be Erwin's hobby of late. Which is just as well, because Levi cleans.

"But you're saying even without those machines, you can't tell you've got dust and shit everywhere?"

Wouldn't that make it more noticeable??
