* ActorAllusion: One of the members of Oversight is portrayed by Alberta Watson, who played Madeline in ''Series/LaFemmeNikita''
** Nathan, Alex's LoveInterest is played by Thad Luckinbill, Lyndsy Fonseca's main love interest as Colleen in TheYoungAndTheRestless.
** Cyrus, a Rogue Division agent turned arms dealer. His sales pitch is evocative of [[Advertising/TheManYourManCouldSmellLike the role that made Isaiah Mustafa famous]].
* FridayNightDeathSlot: Unfortunately, this is most of the reason why Nikita is currently CW's lowest rated show.
* HeyItsThatGuy:
** [[Film/{{X-Men}} Pyro]] is Birkhoff, Division's [[DeadpanSnarker snarky]] [[TechnoWizard tech wizard]] who built the [[OmniscientDatabase Magical Database of Magical Databases]].
** [[Series/HowIMetYourMother Ted's future daughter]] is Alex.
** [[Series/TheOC Julie Cooper]] / [[Series/{{CSI}} Lady Heather]] is resident shrink/[[JackBauerInterrogationTechnique "interrogation expert"]] Amanda.
** Stan Lee describing someone as a "superhero", and acting as Hank [[CatchPhrase Excelsior]].
** Owen's girlfriend Emily played a witch last year on TheVampireDiaries... Her name? [[ActorAllusion Emily]]! She's better known for playing Kendra on Series/{{Buffy|the Vampire Slayer}} and Maya in PrettyLittleLiars, where she dates a girl named [[RuleOfThree Emily]].
** The original Engineer of the entire Black box system is played by the same actor who played the Computer savant Laslo in ''Film/RealGenius''. The character of Laslo went into seclusion after some tech he created was misappropriated by the Govt to create a weapon.
*** For others, he's more recognizable as [[ThePretender Broots]], another computer genius.
** [[Series/TwentyFour George Mason]] is now Percy, the MagnificentBastard who runs Division.
*** And Nina Myers is [[spoiler: Alex's mom]]. (Sarah Clarke [[RealLifeRelative married]] Xander Berkeley [[RomanceOnTheSet after meeting]] on ''24''.)
** And [[ThePhantomMenace Darth Maul]] is Brandon, a Guardian!
** Michael used to be [[{{ER}} a doctor]].
** [[Advertising/TheManYourManCouldSmellLike Isiah Mustafa]] is Cyrus, a rogue Division agent turned arms dealer.
* TruthInTelevision: The episode where Division attempts to kill a Georgian prince has a background in reality. There really is a Monarchist tradition in Georgia (though it's been absent from power for 200 years), and there really was a dynastic squabble settled by the two lines marrying recently, in 2009. All the personal stuff was fake, though.
** Also, Nikita picking at her food in the suburban mealtime in 1x20 because it was a pot roast. She apologises when the kid says she is "busted". This is an allusion to Nikita's actress Maggie Q's real life veganism and animal activism. She is also well-known for ensuring that she works in places that do not use fur, and has changed this when working on certain projects before.
* RetroactiveRecognition: In "Alexandra," that's [[Series/LostGirl Kenzi]] as Alex's friend from her sex slave days. And then Lauren as a terrorist four episodes later ("Girl's Best Friend").
