Soji - Data's daughter? Wait, Maddox made her. No, now Soong's there. Another Soong. Data's alive. (But other poster says, no it's not Data, just a copy and the show's about Picard dealing with Data even though there was tons of plot not related to that. . . .)
Wasn't it stated that Data's conscious was just the copy of what was taken from B4's memory? So it basically is a copy of a copy (and probably not a totally complete copy, since I don't believe B4 was able to store Data's whole mind).
