- In Downfall - A Horror Adventure Game, Doctor Z was killed in real life by Joe himself in the same exact manner as seen in Quiet Haven Hotel. It is unknown, however, if Joe killed Doctor Z in reality during Downfall, with it never even being hinted at.
- Although Xavier Zellman, his brother, uses the initial of his first name for his physician name, Doctor Z uses the initial of his last name instead of his first. This could imply that Doctor Z is the older brother, or he doesn't like Doctor F.
- In The Cat Lady, the last name for the Zellman family is instead "Zelmann", with Dr. X's full name being Dr. Xavier Zelmann and Dr. Z's name being Dr. Frank Zelmann. This is due to The Cat Lady trying to follow the original, now non-canonical 2009 version of Downfall, where the surname was spelled Zelmann.
