When talking about Debbie trying to kill Ray, Nameless Master Villain says that Ray was supposed to have died "this morning." However, earlier dialogue establishes that Ray was shot at the previous day, then moved into Janie's room and broke into the university college room the day after. No more than a day later, Ray says that Debbie tried to kill him "about a week ago."
Ray sits down on what appears to be an Apple II C oder II E computer. The text on the screen also has lower case characters while the Apple II only had upper case characters.
