H'oh! I have no idea how it would ever happen, but were she to run into/interact with Aubrey... There's two fairly large things, one (the fact that xe knowingly let something kill the equivalent of a small city) fairly close and just being Pointedly Not Thought About and another (the fact that xe can get to a mental place where a city is Acceptable Collateral Damage) that xe barely even realizes is there.

Heh. I've been kind of puzzling out how to bring these things more forward, actually. Not entirely sure if I want to ruin Aubrey's brain for a little while yet, though. >.>

Also, this idea wins. By the way.
