[She's glad he trusts her enough to tell her why, but that's about the extent of it.

She can't be glad of anything else -- of a world where Julius had to make that choice to save everything he knew. Because at least the Kumou twins hadn't had to choose to become vessels, that had been pure chance, even if they did end up choosing a lot of things that ultimately isolated them. So, in a way, Okuni can understand having to take up a hard choice, but...

That was more than a hard choice.

Her eyes flash in dismay as she listens, but that's also the extent of which she'll show her emotions. This is a world that Julius has had to live with the entire time...]

I see. I was a little arrogant when I said I understood earlier. ...Yours is a curse you accepted. [a burden willfully undertaken... She understands better now.]

Still, my answer's the same, Julius. I'll use the weapon you give me.

[She doesn't want to.... but sometimes life just doesn't work that way. And better it was her, someone Julius trusted enough to tell her the reasons, then a random bystander.]

Until the day when you decide to take it back.

[rather than, "the day when you lose all your humanity" because really

if he's still alive, then there's always a chance.]
