He's abstractly glad she brought up Hell again, because it's important, but it feels terrible and - aversive to actually talk about it when she's so unhappy to hear what he has to say. "We don't say anyone deserves to go to Hell," he ventures. "Or well, I guess maybe some people do, but almost everyone agrees it's terrible that anyone goes to Hell, it's also just - true.

"I haven't heard of succubi changing men into women, either. I thought they changed themselves, not others. But I've never met one, so I guess I don't really know that, either." He had never been in any danger of meeting a succubus, which meant he had had his share of safe guilty fantasies about it. Ahmose isn't sure what a society looks like that has succubi freely available for anyone who want to talks to one, and is a little scared to find out.
