Editing Seven of Nine (section)

====Joining the crew in "Scorpion"====
Seven of Nine first appears in the second part of "[[Scorpion (Star Trek: Voyager)|Scorpion]]" at the start of the fourth season. She is chosen by the Borg to communicate verbally with Captain Janeway so that together they can develop a weapon to defeat [[Species 8472]]. After a Borg cube destroys itself to save ''Voyager'', Seven is transported aboard the Federation ship. Janeway is injured, leaving Chakotay in command—but he distrusts Seven and the Borg and after he refuses to work with her, she sends the vessel into fluidic space to force them to develop the weapon. Just before doing so, Chakotay decompresses the cargo bay, killing the remaining Borg with the exception of Seven. Janeway recovers and works with Seven and the Doctor to develop the weapon and defeat an attack by Species 8472. With their alliance ended, Seven attempts to assimilate the crew but they override her neural connection to the Collective.<ref name=scorpion2>{{Cite episode |title=Scorpion|episode-link=Scorpion (Star Trek: Voyager) |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Braga, Brannon; Menowsky, Joe|network=UPN |date=September 3, 1997 |season=4 |number=1 }}</ref> Over the course of the following episode, "The Gift", [[Doctor (Star Trek: Voyager)|The Doctor]] removes about 70% of Seven's Borg implants because her body begins to reject the technology once her connection to the Borg Collective is severed. Seven leaves [[sick bay]] to help repair the ship, and while working she attempts to communicate with the Collective but is stopped by Kes. She is placed in the [[Military prison#Brig|brig]] where she and Captain Janeway have a heart-to-heart discussion. Following the departure of Kes, Seven (now restored by The Doctor to her original human appearance) is recruited to join ''Voyager'''s crew.<ref name="thegift"/>

Seven immediately comes into conflict with Chief Engineer [[B'Elanna Torres]] in "Day of Honor" and puts ''Voyager'' in danger when the Caatati steal the warp drive and hold it hostage for supplies and Seven herself. Instead, she builds a thorium generator to power their vessel, which the Caatati accept in exchange for the core and for allowing the rescue of Torres and Lt. [[Tom Paris]].<ref name=honor>{{Cite episode |title=Day of Honor|episode-link=Day of Honor |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Taylor, Jeri|network=UPN |date=September 17, 1997 |season=4 |number=3 }}</ref> In "The Raven", Seven, experiencing visions of the Borg and a [[raven]], steals a shuttle and heads into nearby B'omar space. The aliens would not allow ''Voyager'' to enter their space, but Tuvok and Paris cross the border in another shuttle and head in pursuit. Tuvok beams across to Seven's shuttle, where she explains she's following a homing beacon. They head to a planet where the wreckage of the USS ''Raven'' is crashed on the surface. They transport down and Seven recognises it as her parents' vessel. The B'omar attack but ''Voyager'' comes to their aid and the crew depart. Janeway tells Seven that her parents' research records are in the ship's databanks; Seven replies that she might read them someday.<ref name=theraven/>

After some time, Seven begins to question why Captain Janeway continues to make contact with alien species as they travel back to Earth, as it often results in incidents. Janeway explains that ''Voyager'''s purpose is exploration and will continue that mission despite any problems that might occur.<ref name=randomthoughts>{{Cite episode |title=Random Thoughts|episode-link=Random Thoughts (Star Trek: Voyager) |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Biller, Kenneth|network=UPN |date=November 19, 1997 |season=4 |number=10 }}</ref> While working in astrometrics, Seven detects an ancient alien communications platform which connects all the way back to the borders of Federation space. This results in the first successful communication with Starfleet since ''Voyager'' was stranded in the Delta Quadrant, although it does also result in angering an alien race upon first contact; the [[Hirogen]] had claimed the platform for their own.<ref name=message>{{Cite episode |title=Message in a Bottle|episode-link=Message in a Bottle (Star Trek: Voyager) |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Klink, Lisa; Williams, Rick|network=UPN |date=January 21, 1998 |season=4 |number=14 }}</ref> The crew subsequently receive messages from home through the array, but the ship is once again threatened by the Hirogen. Tuvok and Seven transport aboard the array to speed the downloading of the messages, but are captured and tortured by the aliens. They are rescued by ''Voyager'', but the communications array is destroyed.<ref name=hunters>{{Cite episode |title=Hunters|episode-link=Hunters (Star Trek: Voyager) |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Taylor, Jeri|network=UPN |date=February 11, 1998 |season=4 |number=15 }}</ref> When the crew find a member of Species 8472 being hunted by the Hirogen, Seven is reluctant to help her former enemy as it would put the ship at risk of destruction from the Hirogen. When the Hirogen threaten ''Voyager'', Seven disobeys Janeway's command and transports the alien aboard a Hirogen ship. In response, the Captain punishes her by restricting her computer access and confines her to the cargo bay where her Borg regeneration unit is set up.<ref name=prey>{{Cite episode |title=Prey|episode-link=Prey (Star Trek: Voyager) |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Braga, Brannon|network=UPN |date=February 18, 1998 |season=4 |number=16 }}</ref>

In "[[Retrospect (Star Trek: Voyager)|Retrospect]]", the Doctor accidentally causes Seven to relive repressed memories of while she was Borg. She confers these memories onto an alien she had just met, and the local authorities seek his arrest. The crew realise what has happened, but he is killed before he can be told he is innocent.<ref name=Retrospect>{{Cite episode |title=Retrospect|episode-link=Retrospect (Star Trek: Voyager) |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Fuller, Brian; Klink, Lisa; Shepard Price, Andrew; Gaberman, Mark|network=UPN |date=February 25, 1998 |season=4 |number=17 }}</ref> During the events of "The Killing Game" where the Hirogen take over ''Voyager'' and place the crew in the holodeck for hunting practice, Seven is brainwashed into thinking she was a French club singer during the [[Nazi occupation of France]]. She is the first member of the crew who has her memories restored by the Doctor, and helps Janeway bring about a truce with the Hirogen.<ref name=killing>{{Cite episode |title=The Killing Game|episode-link=The Killing Game (Star Trek: Voyager) |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Braga, Branon; Menosky, Joe|network=UPN |date=March 4, 1998 |season=4 |number=18 and 19 }}</ref> Janeway and Seven disagree once more in "[[The Omega Directive]]" about what to do when the ship detects unstable Omega particles nearby. The Captain wants to destroy them under Starfleet standing orders, while Seven seeks to harness them as the Borg consider the particles to be near perfection.<ref>{{Cite episode |title=The Omega Directive|episode-link=The Omega Directive |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Klink, Lisa; Diggs, Jimmy; Kay, Steve J.|network=UPN |date=April 15, 1998 |season=4 |number=21 }}</ref> Seven must later deal with a series of hallucinations and loneliness while helping the crew cross a radiation-filled nebula in "[[One (Star Trek: Voyager)|One]]". This experience results in her seeking out the company of other crew members more frequently.<ref>{{Cite episode |title=One|episode-link=One (Star Trek: Voyager) |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Taylor, Jeri|network=UPN |date=May 13, 1998 |season=4 |number=25 }}</ref> Her suspicions of Arturis prove correct in "[[Hope and Fear]]" when it is revealed that he was seeking revenge on the ''Voyager'' crew for their previous alliance with the Borg by creating a fake USS ''Dauntless'' and attempting to take them back to Borg space where they would be assimilated.<ref>{{Cite episode |title=Hope and Fear|episode-link=Hope and Fear |series=Star Trek: Voyager |series-link=Star Trek: Voyager |credits=Berman, Rick; Braga, Brannon; Menosky, Joe|network=UPN |date=May 20, 1998 |season=4 |number=26 }}</ref>
