• The former drones were members of the same Unimatrix as Seven. Eight years ago their sphere crashed on a planet and their link to the collective was severed. When they rejoined the collective, they were linked in a "sub-collective" together. Seven of Nine actually created the link when the drones' individuality threatened their survival. After the link is severed by the Doctor, the former drones have 2-4 weeks to live.
