[She isn't annoyed that Knives reaches the water before she can, per se. She just scowls up at him, brief as can be. It doesn't even reach her eyes. Quickly. she's losing the ability to gather her temper around him. Not when he takes everything so well and has been genuinely kind. It's strange that her so-called (and very one-sided) worst enemy had become one of the few people she could trust to respect her boundaries.

So, with all her venom tempered, all she can really do is try to read his movements. Some part of her mind does supply: he's not used to having nothing to do, but she pushes it from her mind. She can't imagine that Knives would be prone to listlessness. Even if he had turned over those new, proverbial leaves, she can't imagine him sitting still.

Surely he would have found something to do.]

I don't think you should have to go out of your way to cook for us. Even if you mean well. [It just feels wrong to have him help out while she's done almost nothing.] There's gotta be something more you can do for yourself. That way you're not feeling beholden to anyone.
