to infect the Borg Collective with a virus designed to shut it down. Thirteen of their people sacrificed themselves to be assimilated so they could spread the virus. Part of their plan depends on more Borg to find the vinculum and use it like a "Typhoid Mary" to spread the virus further into the Borg network. However, Captain Janeway wants to keep the vinculum for a short period of time to give the crew time to separate Seven from it. Seven struggles to maintain control of the personalities splitting her consciousness — including some with memories of the defeat of the Starfleet battle group at Wolf 359 — while Chief Engineer B'Elanna Torres and her team begin the difficult task of shutting down the vinculum. Tuvok suggests a Vulcan mind meld to help calm Seven. The aliens protest Voyager'''s interference with their plan and attack the ship. In the end, B'Elanna is successful and Seven is freed from the link. The vinculum is beamed off the ship and the aliens disengage. In the closing scenes, Seven expresses to Janeway that she is unsure how to thank the crew for their efforts to save her. Janeway tells her to report to engineering to help with maintenance and Seven agrees, but states she has one crew member to visit first. She is revealed to be assigning readings to Naomi Wildman (who had earlier tried to engage her and helped through her alternate personality episodes) to help the girl with her ambition to be "captain's assistant". After giving Naomi several PADDs with the data, Seven tentatively asks Naomi to teach her how to play Kadis-Kot, a board game played among the crew. Grinning, Naomi agrees.
