History Series / BlackHoleHigh

* BestKnownForTheFanservice: "Hemispheres" is a great episode. Not only did the actors do a great job acting the complete opposite of their characters, Corrine got the chance to explore her much-neglected creative side. But what does everyone remember from this episode? Marshall's extremely alluring bad boy alter ego.

* MissingMom/DisappearedDad: Vaughn's mother and Josie's father, respectively.

* WhatTheHellDad? Vaughn has a few of these moments over the course of the show.

* HollywoodScience: Though occasionally averted. Emphasis on the occasionally.

* HoldingHands: Josie and Vaughn's UST really took off in "Lost" when Vaughn suggests they hold hands so [[ItMakesSenseInContext neither of them disappear.]]

* AdultsAreUseless -- Not so much useless but are usually in on the conspiracy.
* AlmightyJanitor -- [[ExactlyWhatItSaysOnTheTin The Janitor]]
* AlphaBitch -- Madison
* BackForTheFinale -- Josie
* BadAssBookworm -- Corrine, Marshall, and Lucas all have their moments.
* BecomingTheMask -- Vaughn, originally TheMole for Victor.
* BetaCouple -- Corrine and Marshall.
* BigBad -- Victor Pearson, at least to all appearances.

* BizarroUniverse -- "Hemispheres", the world at the other side of the mirror Corrine goes through.
* BookDumb -- Vaughn, though this could be due in part to his Dyslexia. And by the end of the series, he seems to have come into his own intelligence wise. Also applies to Stu Kubiak; though even he had some rare bouts of brilliance. Mostly when it involved his pet chameleon.

* ChekhovsClassroom -- Happens in nearly every episode.
* CloningBlues -- Josie, "Culture"; [[spoiler:The clone actually is integral to the story's plot, though you don't find that out 'till much later.]]
* CoolTeacher -- Professor Z
* ConspiracyTheorist -- Lucas
* CrossReferencedTitles - The first episode is titled "Wormhole". "Wormhole Part 2" is not the second episode, but the ''second season premiere''.
* DawsonCasting -- [[AvertedTrope Averted]]. Like a [[Series/{{Degrassi}} certain other]] Canadian TV show aimed at adolescents, they actually decided to hire actors who were the same (or very near the same) age as their characters.
* ADayInTheLimelight -- One or more for each of the characters.
* DidNotGetTheGirl -- [[spoiler: Lucas.]]
* EveryoneCanSeeIt -- The growing attraction between Marshall and Corrine, and the UST between Josie and Vaughn. Even though neither of these couples really dated formally, everyone assumed they were. This is lampshaded by Marshall's friends in the epsidoe "Friction."

* FateWorseThanDeath -- [[spoiler: Josie gets trapped in an alternate timeline where everything is in ruin and she is the only occupant. The worst part is she stayed there for ''a year!'']]
* FieryRedhead -- Josie

** TheHero -- Josie
** TheLancer -- Lucas
** TheBigGuy -- Vaughn
** TheSmartGuy -- Marshall
** TheChick -- Corrine
** [[MentorArchetype Mentor]] -- Professor Z
* FlowersForAlgernonSyndrome -- The premise behind the episode "Transference"; the vortex causes Vaughn to suck more intelligence from Josie, leaving him with the ability to build [[FridgeHorror a cold fusion reactor]] while Josie barely has enough brain power to stay awake. In the end, a [[spoiler: kiss]] snaps everything back to normal.

* FreakyFriday -- "Brainwaves", where Lucas and Vaughn switch mental states.
* GraduateFromTheStory -- "Conclusions"
* GraduationForEveryone -- Averted. [[spoiler: Though most of the main cast ''did'' graduate, Josie--who had been missing for over a year--mentions that she has to take summer school because, unlike the rest of them, she didn't finish high school.]]
* GroundhogDayLoop -- "Thursday", for Corrine.
* HollywoodScience -- Though occasionally averted. Emphasis on the occasionally.
* IdenticalGrandson -- Principal Durst in "Past", when Josie time traveled to when the high school was first built.
* IncredibleShrinkingMan -- Josie, "Shrink".
* ItSeemedLikeAGoodIdeaAtTheTime -- "Radio", "Robot", "Technology". Using leftover Peardyne phlebotinum in an electronics project and have it result in the device developing mysterious [[strike:supernatural]]scientific powers once can be counted an accident. By the ''third time'', it seems like carelessness.
* ItWasAGift -- Professor Z apparently owns a polka CD. He suggests using it to rid the school of rapidly multiplying sponges in "Ecosystem", to the confused expressions of Marshall and Lucas.
* JerkJock -- Vaughn started out as this, but then the trope right below this one happened. Stu, on the other hand....
* JerkWithAHeartOfGold -- Vaughn
* KeepCirculatingTheTapes -- See below example of [[NoExportForYou No Export For You]] as to why.
* LIsForDyslexia -- In "Brainwaves" we learn that Vaughn is dyslexic.
* LivingAphrodisiac -- the protaganist in "Allure." The wormhole turns Corrine's Venus Fly Trap into a teenage girl...who quickly gathers the attention of all of the boys in school. Unfortunately, her motives aren't to date the boys but to eat them for lunch.
* LivingWithTheVillain -- Victor and Vaughn. Briefly toyed with with Josie and her mother as well.
* LoveTriangle -- Josie, Vaughn, Lucas
* LukeIAmYourFather -- In the made for TV movie, we learn that [[spoiler: Avenir is Josie's father]]
* MagneticPlotDevice -- The wormhole.
* MarriedToTheJob -- Victor, Josie's mom.
* MirrorChemistry -- One episode is actually called "Chirality," and introduces the concept in a chemistry class -- then uses it as a justification for a PersonalitySwap episode.
* MirrorUniverse -- "Hemisphere"; here, not an evil universe, but a "mirrored" one where everyone is right-brained (ie., artistic) rather than scientific.

* NiceJobBreakingItHero -- Josie, "Inquiry"
* NoRomanticResolution -- Much to the chagrin of fans, the movie left much to be desired in the way of shipping.

* NoExportForYou -- A DVD set of the first season ''was'' going to be released in the U.K. ONLY.... but then the trope was [[AvertedTrope averted]] when the release ''was canceled without any explanation whatsoever'', turning this instead into a case of [[KeepCirculatingTheTapes Keep Circulating The Tapes]].
* OneLetterName -- The kids call Professor Zachary "Professor Z." Or, in some cases, just "Z." He doesn't seem to mind or even notice.

* RealLifeWritesThePlot -- After the end of the third season, Fireworks Studios, who produced the show and provided its lifeline, closed down with short notice, and only left enough time for the crew to create a three episode-long finale, rather than the fourth and fifth seasons that were planned.
* RedHeadedHero -- Josie
* RetCon -- The final episode of Season 3 shows Josie arriving at a shuttered and abandoned Blake Holsey High with the war-torn ruins of a futuristic city in the background, the implication being that she's traveled to an AfterTheEnd future. The finale miniseries repeats the shot, but the city in the distance is gone, and it's later explained that she was shunted into some sort of pocket universe to protect the timeline from her meddling.
* SchoolPlay -- Romeo and Juliet in "Brainwaves".
* SetRightWhatOnceWentWrong -- "Fate", "Wormhole Part 2"

* ShoutOut -- Marshall's last name is Wheeler. This is most likely a shout out, considering the fact that [[http://en.wikipedia.org/wiki/John_Archibald_Wheeler John Archibald Wheeler]] is the man who coined the terms "Black Hole" and "Wormhole". Victor Pearson may also be a reference to [[http://en.wikipedia.org/wiki/Victor_Popov Victor Popov]], and though a long shot, Vaughn may be a reference to the name Sean, since Robert Clark's (the actor who played Vaughn) brother is Daniel Clark, who played Sean on ''Series/{{Degrassi}}''.
* SyndicationTitle -- ''Strange Days at Blake Holsey High''
* TeenGenius -- As science buffs, technically EVERYONE is one (except maybe Vaughn), but Corrine fits even more so than the others.
* TheSleepless -- The episode "Nocturnal" is devoted to this trope. Josie becomes unable to sleep thanks to the wormhole influence. She starts developing hallucinations of Vaughn's memories.
* TheSnarkKnight -- Sometimes Josie comes off as this.
* TheTalk -- When Z loses his memory in "Who?", Lucas and Marshall attempt to jog it by teaching him scientific concepts. Unfortunately, one of the things Z asks them to explain is reproduction.
-->'''Marshall:''' There is ''no'' way I'm giving him TheTalk. My dad had a hard enough time explaining it to ''me.''
* TheWatcher -- The mysterious janitor.

* TimeyWimeyBall -- Literally. Josie takes a Qi Gong ball through the wormhole, which somehow negates its gravitational field. While time traveling, she loses the ball to a young Victor Pearson, who uses it as the basis for the original Pearadyne experiment which created the wormhole in the first place.
* TimeAlteringMacGuffin -- The Qi Gong ball.
* TimeSkip -- Between Season 3 and the movie.
* TooDumbToLive -- Marshall is stunningly incautious for someone who knows about all the weird things going on.
* ToughLove -- Vaughn's father borders on this with ParentalNeglect. He expects his son to carry on with his work, but shows no interest in him unless he's done something very right or messed up his plans. Vaughn is constantly trying to seek the approval of his father and never gets it.
* TwoTeacherSchool -- Again, literally. The only teachers we see are the science teachers- one of whom only appears in two episodes. In fact, it would seem the only other faculty at the school are A) Principal Durst, B) The Janitor, and C) The Lunch Lady.
* {{UST}} -- Vaughn and Josie (though {{Fanon}} would have you believe they had sex at some point), as well as when Vaughn and Corrine get stuck to each other in "Friction". Heck, even [[ExactlyWhatItSaysOnTheTin the title admits it]].
* WellDoneSonGuy -- Vaughn and Victor's relationship is strained.
* WholePlotReference -- "Invisible" references the ''[[Series/BuffyTheVampireSlayer Buffy]]'' episode "Invisible Girl", "Thursday" is a take off on ''[[Film/GroundhogDay Groundhog Day]]'', "Pheromones" is a take off on ''[[InvasionOfTheBodySnatchers Invasion of the Body Snatchers]]'', and "Probability" is a take off on the short story ''Behind the News'', the latter two listed both being (originally, anyway) stories written by Jack Finney.
