[If Knives notices that Vash is uncomfortable with him holding something that could be used as a weapon, he doesn't show it. At least he doesn't acknowledge it obviously. He does, however, move it to the sink so that it's not close in his reach after that first bite of the sandwich before returning to stand next to his brother and eat a bit more.]

I know.

That's what you wanted, isn't it? To save everyone and to have them all live peacefully. [He makes a soft, annoyed sound as he rips a piece of bread off the top of the sandwich.]

And yet you also just told me that the Down could use more food as if there wasn't plenty of it up here that the Up could share.

I wonder... what stops them from doing that? [He asks in that tone that says he knows exactly why. Because humans need someone to prey on, even if it's other humans - maybe even especially then. He pops the bread into his mouth and considers his brother as he chews, as if waiting for him to answer.]
