Unicomplex? What unicomplex? That concept wasn't invented until VOY. The cube could have been the equivalent. Guinan didn't say anything about cubes. The cube could have been the mothership which launched the swarms. Guinan said "when they come, they'll come in force... they don't do anything piecemeal... when they left, none of my people were alive." The intro to BOBW is in line with this. They find a planet that the Borg attacked, everyone is dead. The admiral says "we've known this was coming for a year." It was quite obviously the sequel to Q Who and the conclusion of that arc. And you still haven't responded to what I said about TDM. For some reason, you say the only "suitable wrap-up" would be the complete, unambiguous wiping out of the entire species, but this mysteriously isn't a requirement for any other similar stories. When has this ever happened with other powerful beings or technology? Whether there were more planet killers was still up in the air. Okay, you've lost me.
