I never saw this one first time around in First Run. I always thought Chakotay and Seven as a couple came from out of Nowhere. It still was random, but, at least this episode gives us a little bit of an explanation. Seven fantasizes of having her remaining Borg Tech removed, and starts to allow herself to fantasize about a relationship (Thanks to her Unimatrix Zero experiences) and she falls in love with Chakotay. And then of course, her Borg Tech fights back against her new level of regained emotions. I actually enjoyed seeing Seven let down her guard in this episode. I thought it was kinda bizarre that she would want to be totally free of her Borg Tech, though, wouldn't that fundamentally weaken her knowledge Base? Can a Human brain hold and control all the knowledge she has assimilated without the mechanics?
