...She'd been around for a while. Like an assistant, you know? I wanted to see if I could get answers out of her, to see if she'd react differently to things than most humans do.

She was just like the rest in the end, and she was annoying as hell on top of it. So I decided I wanted to get rid of her.

[He shrugs a bit, though eye contact isn't exactly a thing.]

I don't know. The original choice didn't involve her, it involved deciding between sparing the guy she liked and sending some person she didn't know to the Void. Whatever she said wouldn't matter for either of the other people - the guy she liked had already been sent to the Void and there wasn't any saving him from that, and I wasn't going to touch the other person based on her decision because no? Even I get that that's not something you do, and I'd catch hell for it from Nona even if I didn't. What mattered was the choice. Leaving her guy dead would get her reincarnated, killing the stranger would get her sent to the Void, that'd be it.

She just decided to go herself instead of sending somebody else, and I didn't argue with her because she was still making the damn choice for me.
