Before he was known as Dr. Flug, the most lethal mad scientist in the world, the brains behind Black Hat Organization, he was just a teenage genius born into a family of heroes. Then one day, a traumatic familial experience, a welcoming hand from a villainous woman, and a conversation on morality have him changing course mid-flight.

Black Hat's gone, but Flug is still terrorized by his memories. Luckily Demencia is there to help him through the night. FlugxDemencia, PaperLizard, cute, fluff, angst, post-BHO, happy ending.
