I find the ending to "I, Borg" perplexing. One, no one bothered to remove the Borg implants from Hugh in the first place. The series proved that Borg implants could be removed in the case of Picard. But not once did anyone consider to do this to Hugh. And two, why did Hugh give up Picard's offer to become a Federation citizen. Hugh's explanation that the Collective would come looking for him did not make any sense to me. They didn't bother to hunt down Picard after he had ceased to be Locutus. Why would they hunt down a drone no longer connected to the Borg Hive? And if they had remove Hugh's Borg implants in the first place, perhaps the writers would not have come up with this ridiculous ending.
