What did Seven of Nine stand for in Voyager?

Humanity in general, I think, is one of the things that Seven allowed them to explore, through the character. She brought conflict to the show, which was sadly lacking. Once the Maquis made up with Janeway and company, it was just one big happy family.

I think they were really looking to add some edge to the show and add some conflict, because that�s drama, that�s what makes it interesting to watch. More than anything else, I think, that�s what Seven brought. Also, in grand Star Trek tradition, Seven of Nine was an outsider who could comment on humanity and all of its foibles. Also, it was a foil for Janeway�s character, someone to explore more levels of Janeway�s humanity in teaching Seven about hers.
