History Recap / StarTrekVoyagerS5E7InfiniteRegress

** To the Battle of Wolf 359, when Seven manifests a [[TearJerker Mrs. Bergen, whose son was killed in the battle while she was assimilated]] Ensign Stone's ship was also apparently assimilated given her comments during the episodes climax.

** A Vidiian (from seasons 1-2) is briefly visible among the crowd of personalities in Seven's mind. Presumably the Phage isn't a problem for the Borg; presumably they felt getting access to Vidiian medical knowledge was worth the trade-off.

* AgentScully: Shockingly, the Doctor, who calls a proven [[MindMeld form of contact telepathy]], which he's ''seen'' work "Vulcan mumbo-jumbo." Granted, he ''is'' upset about Seven, but still!
** Given that he's seen it go badly in "[[Recap/StarTrekVoyagerS2E16Meld Meld]]" and "[[Recap/StarTrekVoyagerS3E15BloodFever Blood Fever]]", the Doctor's objections are presumably based on its unpredictability.
* ArtifactOfDoom: The Vinculum, the CPU of a Borg cube which erases individual thoughts and merges drones' minds with the Collective: bringing order to chaos. This one, separated from its destroyed Cube and infected with a virus from another assimilated species, 6339, is malfunctioning and sending errant commands to Seven's cortical implant, bringing out the assimilated victims: [[IronicEcho chaos to order]].

* BattleInTheCenterOfTheMind: In addition to shutting down the Vinculum, Tuvok must also perform this. It takes the form of billions of souls separating Tuvok and Seven, including a DestinationDefenestration, but they all vanish once the Vinculum is killed.

* BookEnds: To little Maryl, who played Kadis-kot (a form of TabletopGame/TicTacToe with colors?) with Naomi; at the end, aside from helping Naomi prepare to be 'Captain's Assistant' (a role Seven previously stated was non-existent), Seven herself requests to be taught how to play the quirky children's game.

* FictionalSport: Kadis-kot.

* HopeSpot: It seems like choking out the Vinculum with a TechnoBabble is going to work, but like all Borg technology, it adapts, and Seven's own neural pathway is totally submerged in favor of the potentially hundreds of others.

* JerkAss: Species 6339, who want to use the Vinculum to continue to infect Borg with the virus they created, with symptoms similar to Seven's, which is... [[AlwaysChaoticEvil somewhat justified]], but they refuse to let our heroes shut it down in order to save Seven and continue attacking even as the MindMeld goes on!

* LargeHam: When Seven's other personalities emerge.

* SplitPersonality: Sometimes coming on SO fast it's shocking.

* BiteOfAffection: The son of K'vok (in Seven's body) [[LesYay hits on B'elanna in the Klingon way]], including a [[BelligerentSexualTension bite on the cheek]].

* DidYouJustPunchOutCthulhu: Well, as much as the Vinculum is 'alive,' because it adapts, has self-preservation instincts, etc., but B'elanna finally manages to kill it.

* InnocentInaccurate: Naomi's back! And she's a bit nonplussed by Maryl, but recovers quickly.

* [[KnownOnlyByTheirNickname Known Only By Their Borg Designation]]: Species 6339.

* TheMirrorShowsYourTrueSelf: The Klingon (presumably the son of K'vok) seen as a reflection when Seven is stealing from the kitchen. Similarly, the reflection of a little girl in Seven's Kadis-kot board.
* MoodWhiplash: Seven herself goes through this, shifting from an angry Klingon, to a scared little girl, to a logical Vulcan, etc.

* OOCIsSeriousBusiness: Everybody gets alarmed at how the typically stoic Seven is suddenly exhibiting emotional personalities. Naomi in particular finds it strange that Seven is suddenly open to playing games with her when she's possessed by a 6-year-old's personality.

* SuddenlyShouting: Seven (as Son of K'vok) trying to get it on with B'elanna. "Your blood is '''''SWEET!!!'''''"

* SuddenlyShouting: Klingon!Seven trying to get it on with B'elanna. "Your blood is '''''SWEET!!!'''''"

** One of the personalities mentions her son was serving on the ''USS Melbourne'', which was lost at the Battle of Wolf 359. In the ''Series/StarTrekTheNextGeneration'' two-part episode "[[Recap/StarTrekTheNextGenerationS3E26S4E1TheBestOfBothWorlds The Best of Both Worlds]]", Riker got offered to command the ''Melbourne'' in Part I but turned it down, and Starfleet's Borg expert, Commander Shelby, specifically points out the destruction of the ''Melbourne'' in Part II.
