Yes. But anger while she is like this is not helping her. It makes it harder for her to be herself, and exhausts her. He is not pointing out that anger over long-dead people, for the most part, helps nothing at all. Knives is not and never would be the person for whom that would matter.

But it matters to Vash.

There is nobody here but her and me and the sisters. The ghost of Wolfwood was here, but I think he went elsewhere to rest, he was trying very hard to protect me, and the material world is not what he does best, not this one. Beat. This is separate from the Wolfwood I was talking about before!

Not for any other reason than to avoid distracting Knives from what needs to be done with any, unlikely as it might be, concern about Vash himself. He's fine. (He's not fine, but that's beside the point. He's not broken by that loss. Yet.)

And yes, all that babble is to distract himself from trying to object to the truth he 'hears' in Knives' words. A life for a life.

Except... his life would not be enough to restore a dying bulb plant. Barely, but not enough. Or he would have been gone long before now. UselessUselessUselessUseless

I'm sorry. That he can't do it himself. Because even with the 'it's not necessary', this is what he feels. I'm doing my best... to not let any of it get any worse.
