Oh WOW. I love this, and I LOVE your use of the prompt. Hojo appealing to Lucretia here just hurts in the best way possible (OH THAT CANON BURN). I have a lot of thoughts about this particularly disturbing triangle, and the way you've set it off here is just... ugh yes.

She likes the clean sterile scent of the labs, of the mako, as she likes her threat and her danger and her transgressions, her trespasses against the laws of man (such as they are not, in the world of Shinra)

Wow, ouch, yes.
