Yeah, I'd love to hear the writer's room justification for that one. If there had to be a romance with Seven, even Harry Kim would be a better choice. At least he admitted he was attracted to her.
If they had actually given a shit and showed us what happened when Voyager got home, I would have liked to think that, since the mission was over, Janeway and Chakotay could finally admit the feelings they had for each other that was made clear in the early episode where they were stuck on that planet for ages.
