During the science fiction convention, there is an announcement that 7 of 9 is signing in the Alpha room. 7 of 9 is a character from Star Trek: Voyager (1995), a series in which Robert Picardo, who plays A.Z. Weyland, played the Emergency Medical Hologram.
One of the fans at Weyland's table is wearing Nemesis's headband from Nemesis (2012). Nemesis is an imaginary superhero who was made up by Brady, and who appeared onscreen only as a hallucination experienced by Daniel.
