Det finns faktiskt en mycket intressant Extended Universe-historia i frågan.
I kortfilen TNG "Jag blir död" , Barn av Soong "(Soong-typ androids som Data, Lore och B-4)
are, by the 44th Century, in control of much of the galaxy and begin systematically suppressing and wiping out organic humanoid life. Data is still alive and functional at this time, but laments the course of events. Commandeering a Federation timeship, Data travels back to the 24th Century believing that if he hadn't transported Lore into space, Lore would have continued on a path that would have discredited androids. Data believes that his own reputation as a "good android" allowed androids to gain the trust of humanity, thus paving the way for android rule. Now in 2364, Data takes over a Pakled ship in the vicinity of where he expects Lore to be drifting. They find him, but he is damaged beyond repair. Data subsequently decides that he himself will assume the role of Lore.
Implikationen är att Lore vi ser i "Nedstigning" Delar I och II är faktiskt Data . Ironiskt nog avaktiverar den 24: e-talsdata och demonterar honom, så historiken upprepar sig eventuellt.
