He Who Fights Monsters
Sofia's ex-husband and frankly kind of a jerk.
Reginald is Sofia’s bitter ex-husband who tried to scam her out of some savings. He no longer works as a professor for the University of Southwestern Illinois and now works for the International Archaeology Institute.
It turns out that he, along with the Institute, have been working to keep demons sealed. Their recent project, to keep the demon Beelzebub sealed, was accidentally thwarted by the Jonesboro hunters — partly due to Reginald’s suspicious and snooty attitude.
