Star Trek: 10 Things You Didn't Know About Seven Of Nine

The initial casting sheets for Seven Of Nine actually referred to the character as Perra. This iteration of Seven would have ended up as a very different character from the one that audiences eventually received.

Perra had been witness to the slaughter of all of her friends and family, while located on Kelta Prime. After this event, she claimed that her humanity died. Unable to deal with the torment of losing everyone she had ever known, she found comfort in the collective consciousness of the Borg.

This goes a way toward explaining some of her reluctance to leave when she is liberated by Captain Janeway. In the Gift, it is explained that she was assimilated as a child, but the circumstances of her assimilation aren't truly explored until Dark Frontier. Annika Hansen, as the character was later renamed, was captured as a young girl when her parents vastly underestimated the Collective. Raised as Borg, this would explain her resistance to humanity.

While certainly traumatic, it is oddly a less bloody introduction to the Borg for the young girl, so in a way, this is closer to a happier ending for her.
