Apparently 'experiments' and 'shifts' are so common that several simply assumed I was he. It is ...refreshing to encounter someone who knows otherwise so quickly.

[Which seems genuine enough. It might be a common headache for identical twins, even though they rarely spent a lot of time around each other. It's true that at their most base points both Vash and Knives are very alike, but everything built on it.. well. Vash won't have the same issues with racist hatred that his brother has.

..Probably for the best.]

We are not human. [He seems willing to clarify, and there's nothing really imperative behind it, it's simply information.] We may look like them, and sound like them, and even act like them at times, but we are not. We're plants. Not like the ones growing here, closer to 'power plants' than anything related to a vegetable. Vash and I are the only living male members of our species. The rest are female, and most of them live in a communal mind-link. We are outside it, and thus are 'independent'.

[Knives pauses, turning a bit to consider Luke directly again.]

You are human, are you not? Is your species space-faring? You seem too .... calm to be a member of the parasitic and virulent sort of humanity I know of.

[Calm isn't the word he wants, which annoys him. But it's the closest he can get.]
