Seven has been using Voyager 's holodeck to try to experience what it would be like to be more human; she enjoys a simulation of the upcoming baby shower for Paris and Torres, and starts to develop a relationship with a computer-generated Chakotay. Outside of the holodeck, though she has been invited to the baby shower, Seven declines. Tuvok assures her that despite their mutual discomfort at such social situations, they are good for morale and encourages her to attend. Seven still decides not to go, and later discusses her feelings while seeing the Doctor about malfunctions in one of her Borg implants. The Doctor finds he cannot extract the implant, which reminds Seven that she is not fully human.
Sometime later, Voyager is knocked out of warp by a nearby explosion. Though the ship is unharmed, they investigate the source of the explosion and find it was from a warhead launched some distance away to a nearby beacon. Fearing that another warhead may actually harm the ship. Captain Janeway orders Seven to find a method to detect the warheads to give them time to evade them. Seven works with Icheb in the Astrometrics lab. She also continues to use the holodeck, the relationship with the virtual Chakotay becoming more romantic.
Seven begins to have difficulty separating the events on the holodeck from that on the real ship; she interrupts Torres during a situation in Engineering to present her with a baby shower gift, mimics some of the behavior she had towards the holodeck Chakotay with the real version, and becomes short-tempered at Icheb. As a result, she fails to complete her assignment, and Voyager is rocked by an explosion from another warhead, closer than the last. Janeway speaks to Seven, seeing that she is distracted, and has Chakotay keep watch on her. Seven goes to the holodeck to break up with the virtual Chakotay, but see suddenly feels pain from her implants, and calls for the Doctor. The Doctor appears in the holodeck, sees the program that she is running, and then has her transported to Sick Bay. After some operations, Seven regains consciousness, and tells the Doctor she plans to delete that program; instead the Doctor encourages her that she just needs to find the balance between her personal life and her duties.
Seven returns to Astrometrics and completes her assignment; they discover a series of warheads approaching Voyager but are able to safely evade them without damage to the ship. Later, the Doctor tells Seven that he believes her Borg implants had malfunctioned as a failsafe that triggered if a drone would even gain back their emotions. He suggests he could remove them after a long series of surgeries, but Seven declines, believing it necessary to keep her focused on her duties. When she later encounters Chakotay, he invites her to a dinner party for the senior crew that even Tuvok is attending, but she declines and walks away.
