Further research of her parents' mission lead Seven to conclude her parents underestimated the Borg, which eventually led to their assimilation. It was during this research that Seven discovered the Hansens' description of a bio-damper in their notes, which they used to move around undetected in a Borg vessel while conducting their field research. The Voyager team replicates the technology for use in their raid on the Borg sphere. Asserting that she is willing to risk her own well-being for the sake of the crew, Seven persuades Janeway to assign her to the away team despite the Captain's reservations.
