His name is randomized when Sim State University is generated. The name "Aiden Reamon" is only referenced in the game files. Strangely when editing in SimPE, Sam Thomas recognizes Aiden as her uncle, but the relation isn't mutual, as Aiden doesn't even know who Sam is. Jane Stacks also recognizes Aiden as family, however the relation type is undetermined, and Aiden does not recognize Jane as family, nor does he know her either. The reasons for these unlikely family connections are unexplained, but there are a few other Sims from University that have these sorts of quirks.
