Ah, but how the hell were there survivors and how did they get back to the collective?? The single invading Borg cube itself was destroyed at Earth. [/can of worms]I would say that the combined Federation/Klingon forces at Wolf 359 probably opened fire on the Borg cube first and they retaliated! As we know from the later VOYAGER episodes, the Borg took many of the survivors aboard and converted them into drones! Were there any Romulan ships there because one of the survivors in Unity was a Romulan who had escaped from the Collective!
