History YMMV / OrphanBlack

** [[NotSoWellIntentionedExtremist Evie Cho]], the BigBad of season 4, is the ambitious, high-ranking, [[Characters/OrphanBlackTheNeolutionists Neolutionist]] [[CorruptCorporateExecutive CEO]] of [=BrightBorn=]. A survivor of a birth defect, Cho developed a perfectionist view, which inspired her goal to control the future of human evolution. Cho developed mechanical, worm-like devices to alter people's DNA and can quickly but painfully kill it's host if ruptured. When Beth Childs was investigating the Neolutionists, Cho tried to get her to kill Susan Ducan, so she can usurp Duncan as leader of Neolution. Failing that, Cho blackmails her into killing herself by threatening the other clones. It's also revealed that she had Delphine Cormier shot at the end of season three. When Cosima explores [=BrightBorn=] facilities, she discovers Cho is keeping pregnant women in maternity labs for illegal human experiments. When these experiments result in the babies being born deformed, or any other imperfection such as blindness, Cho would have the [[WouldHurtAChild babies euthanized]] to cover it up. Cho has Cosima's research to help cure the clones diseases destroyed, and has Kendall killed and incinerated in front of Cosima, making it impossible for the clones to find cures. To further wound her, Cho tells Cosima that Delphine is dead. She plans to put her devices into millions of people and alter their DNA without their consent. She has Donnie arrested with threats of having him killed in jail to blackmail Allison. When two women escape her maternity lab with evidence that could expose her, she sends assassins after them. When exposed and given the option to resign and absolve [=BrightBorn=] of any wrongdoings, she refuses, her VillainousBreakdown when the project might move forward without her showing she doesn't so much care about controlling human evolution, as much as she cares that [[ItsAllAboutMe she's the one doing it]].

** By the series finale, most of the ''central'' questions have been answered, though there are still several significant cases of WhatHappenedToTheMouse regarding peripheral characters. Some of these, to be fair, may have been cases of RealLifeWritesThePlot necessitated by actors' commitments to other shows (e.g., Creator/MichaelHuisman's to ''Series/GameOfThrones'' and Creator/MichaelMando's to ''Series/BetterCallSaul'').

* FoeYay: Rachel and Sarah. Rachel and everyone, really.

** The notion of Beth as asexual seems to have been definitively {{Jossed}} by the season 4 première.
* GermansLoveDavidHasselhoff: One of very few Canadian series to become a hit south of the border, and gave BBC America its first hit that is neither a [[Series/DoctorWho fifty-year old titan of a franchise]] nor a [[Series/TopGear reality show]] (and ironically enough, with a ''Canadian'' show). The fact that Tatiana Maslany's Emmy snub caused a bigger fuss than any other that year just proves how buzzworthy the show is worldwide.

** Delphine's Season 3 arc has proven to be a ''major'' bone of contention with Cophine shippers: [[spoiler:breaking up with Cosima, torturing an incapacitated Rachel, spying on Cosima and Shay, even threatening to ''kill'' Shay for possibly being a Project Castor mole. The RageBreakingPoint for many was Delphine's CliffHanger shooting, which many accused of being nothing more than a BuryYourGays plot twist.]] However, in season 4, [[spoiler:Krystal, who witnessed the shooting, reveals that Delphine may have survived, and Krystal is confirmed to be correct in 4x09.]] Ultimately, [[spoiler:Delphine ends up surviving the entire series; the finale has her head out on a quest with Cosima to cure all 276 of the surviving Leda clones.]]

** Season 4 has mostly averted this, but fans are somewhat divided about [[spoiler:whether Rachel deserves ultimate redemption after her HeelFaceRevolvingDoor and whether the Neolution founder being alive is a good twist. For the former, it's been pointed out that while she may turn on the clones, she does give the appearance of having been [[UnwittingPawn manipulated by the visions in her prosthetic eye]] and that since she ultimately patches Susan up after stabbing her she may not be completely irredeemable, while others feel that her betrayal of Leda and aggressive attempt to take over Neolution are unforgivable.]] For the latter, some people feel it takes the show too far out of the mostly hard science-fiction approach it has taken thus far, while others are willing to see where the showrunners go with it. (For what it's worth, the show is canonically in a [[TheVerse shared universe]] with ''Film/GingerSnaps'', which, you know, contains [[OurWerewolvesAreDifferent werewolves]].) [[spoiler:For Rachel, the show ends up [[TakeAThirdOption taking a third option]] regarding her redemption; while she ultimately makes a HeelFaceTurn, she is not EasilyForgiven, and she understands that she has crossed too many lines for Clone Club to truly trust her. "Westmoreland" is ultimately revealed to be an impostor who took advantage of the fact that [[NeverFoundTheBody the real Westmoreland's body was never found]].]]

** [[AbusiveParents Henrik "Hank" Johanssen]], from season 2, stands out as a depraved character even in a show full of BlackAndGrayMorality. Johanssen is the leader of a branch of [[Characters/OrphanBlackTheProletheans the Prolethean]] {{cult}}, operating on a ranching community. Separating from the Prolethans' more traditional views in favor of scientific curiosity, Johanssen operates his branch, and seemingly peaceful community, as a BreedingCult, where women are artificially inseminated and children are regularly abused. When Hank gets his hands on Helena, discovering she's a rare fertile clone, Hank has her handler Tomas killed so he can keep her. He proceeds to drug and forcibly marry Helena before [[MedicalRapeAndImpregnate taking her ovaries and fertilizing them with his sperm]], planning to implant those embryos in multiple women. When Helena escapes with the help of Hank's teenage daughter Gracie, Hank has Gracie locked in a cage and her [[MouthStitchedShut mouth sewn shut]] as punishment; it's implied this is a usual punishment for her. He shows more affection towards his follower Mark than he does Gracie and even then he's controlling and indifferent to Mark's feelings; it's discovered Mark, a Project CASTOR clone, is merely a replacement to Abel, a stillborn attempt of Hank's recreating project CASTOR. When Helena returns, Henrik has her inseminated with their embryos before proceeding to do the same with Gracie. He keeps them locked in a nursery, holding them at gunpoint and sends his wife to find more women for him to impregnate. While hiding behind a thin veil of a warm fatherly demeanor, Hank's motivations are that since a fertile clone is a scientific impossibility, he's the only one worthy of fathering children with them and spreading the genres of "miracle babies."

* ParanoiaFuel: Where to begin? The notion that you are not completely unique? The idea that [[spoiler:some company has a patent on your DNA?]] Being hunted and not knowing why? Spending every day in a state of existential crisis? Nearly everyone in the world has been told once that they look like someone else...this show takes that and runs WILD with it. Enjoy thinking on that next time someone says you look a lot like a friend of theirs...

** In the first season, he was able to stand being tortured by [[spoiler:Alison]] and [[spoiler:not let it slip he was her monitor. By the second season, he carelessly leaves his Neolutionist contact phone in his coat pocket, and does a laughably bad job of trying to tail Alision after falling for a trap set by her.]]

** Vic being an incompetent drug dealer is now this thanks to his actor being in ''Series/BetterCallSaul''.

* IconicOutfit:
** Sarah's [[https://s-media-cache-ak0.pinimg.com/236x/79/45/29/7945299bc082841926d33f95d22d3d69.jpg punk-rock outfit]] in the series premiere and her [[https://s-media-cache-ak0.pinimg.com/564x/f7/57/60/f75760555a04dc79331fdcd33697f6ed.jpg outfit]] for most of Season 2 are the most remembered.
** Alison's pink running shirt, white vest, and blue headband.
** Cosima's bright red coat.
** Helena's green coat.
** Beth's purple dress which she wore during her suicide.
** Krystal's form-fitting red minidresses and push-up bras. [[spoiler:Her well-manicured nails help Delphine figure out that Rachel switched with her]].

* {{Moe}}: Delphine is often compared to a puppy.

** Some of Stephen [=McHattie's=] hamminess in the last few episodes can get pretty silly, and act as a sudden reminder that this is the guy who also gave us [[Series/StarTrekDeepSpaceNine "It's a FAAAAAAKE!"]].

** [[ImmortalitySeeker Percival T. "P.T." Westmoreland]], aka [[spoiler:John Matheson]], the BigBad of the 5th and final season, is the [[GreaterScopeVillain ultimate villain of the series]], [[spoiler:posing as]] the founder of Neolution and has been [[TheManBehindTheMan behind all its atrocities]]. [[spoiler:Stealing the real Westmorland's identity]], he goes on to create a {{cult}} to his name on an isolated island while he runs Neolution behind the scenes. Seeking {{immortality|Immorality}}, he sustains himself by taking the blood of the [[WouldHurtAChild children]] of his cult, resulting in some of them dying; and even experiments and tortures a boy named Yanis, driving him feral before eventually killing him in front of Cosmia. His next plans is to find, harvest and fertilize eight year old Kira's eggs, to spread and study the "Fountain of Youth" gene in her offspring, something he is steadfast in [[spoiler:even when his true identity as Matheson is exposed]]. Viewing the project LEDA clones as little more than experiments, he feigns a fatherly affection to Rachel, while secretly spying on her every action through her prosthetic eye. When the truth and Neolution is exposed, he becomes more unhinged; has Helena abducted to force her to give birth to her twins for further experiments; kills [[spoiler:his backers]] to [[HeKnowsTooMuch cover his tracks]] as much as possible; and has Dr. Virginia Coady kill [[spoiler:Mark]] now that the project CASTOR clones [[YouHaveOutlivedYourUsefulness served their purpose]]. It's revealed his end goal is to create a serum that would permanently reverse cell damage for the [[PoliticallyIncorrectVillain upper class--mainly himself--and have the rest sterilized by the CASTOR pathogen. Ultimately, [[spoiler:John Matheson]] is little more than a selfish madman that manipulates an ideology and orchestrated atrocities for little more than his personal power, and [[spoiler:the expansion of his own life]].

* VisualEffectsOfAwesome: Any scenes where there are more than one clone featured are done brilliantly to the point where you forget that all of these characters are being played by the same woman. [[spoiler:They get four clones on screen at once in the Season 2 finale ''and'' both the first and last episodes of Season 3, and as usual, it's seamless.]] Series 5 takes it UpToEleven with a scene where [[spoiler:Sarah and M.K. have a long conversation filmed as TheOner, with both of them freely crossing to each other's side of the screen.]]

* BadassDecay: [[spoiler: Donnie]]. In the first season, he was able to stand being tortured by [[spoiler: Alison]] and [[spoiler: not let it slip he was her monitor. By the second season, he carelessly leaves his Neolutionist contact phone in his coat pocket, and does a laughably bad job of trying to tail Alision after falling for a trap set by her.]]
** [[spoiler: This is a result of him never being a monitor who was "in the know" in the first place. In his confrontation with Leekie, it's made clear he didn't know the full extent of the monitoring or anything about the real reason they were doing it.]]
** Also subverted, as [[spoiler: he [[TookALevelInBadass gains several levels in badass]] after accidentally killing Leekie and blackmailing Vic and Deangelis to stay away from his wife]].

** Rachel has two types of opinions about her. She's either a villain who lost all chance of being redeemed when she [[spoiler: [[MoralEventHorizon kidnapped Kira]]]] or she's a JerkassWoobie who got a little too caught up in her determination to find out what makes Sarah so special.

** Alison's story-line in season 3 has proved to be polarizing. There are quite a number of fans annoyed at how Alison isn't actively involved with the main plot, saying that you could cut out most of her [[spoiler: drug-dealing]] scenes, and not miss an entire thing about this season. Others argue her and Donnie together make for the most hilarious scenes of the season which is needed given how serious the other plots are.

** The reveal that [[spoiler: the genetic template for both the CASTOR and LEDA clones is Mrs. S' mother, Kendall (she is a chimera, a real life condition), has split the fans. Some believe it is a fantastic twist that adds another layer to Mrs. S and Sarah's relationship and is fitting for the show's tone, while others believe it is too much of a coincidence to be taken seriously. In the twist's defence, Kendall is revealed to be directly responsible for getting Sarah and Mrs. S together in the first place, so it's arguably not a coincidence at all.]]
** The season 3 finale reveal that [[spoiler: Neolution is in control of both Topside and the military led to arguments whether it is a good way to organize the various layers of the clone conspiracy and return the show to its season 1 state, or if the show is getting tangled in its own mythology.]]

** The lesser Proletheans, Mark and Bonnie, qualify as this for the ''creators'' because their actors put in such good performances- Mark turns out to be [[spoiler: a male clone, giving Ari Millen the reins of several characters]] and WordOfGod says Bonnie will be [[spoiler: moving up in villain status come Season 3.]]

** Pupok was beloved immediately from the get-go. [[spoiler: His "death" saddened some]]. Except among those fans who are also arachnophobes.

** Try re-watching Sarah and Art's season 1 interactions with the knowledge that [[spoiler: Art was in love with Beth the whole time.]]

* HesJustHiding: This is what a lot of fans assumed for [[spoiler: Helena and Beth]]. Also called [[MemeticMutation the ballpit of denial]].
** [[spoiler: Helena's fans were right. Not dead, after all. In fact, despite being shot a ''point blank range'', she ''walks'' into the [=ER=] and calmly informs them that her sister shot her. Explained later thanks to the Proletheans - her organs are on opposite sides.]]

** [[spoiler: Helena]] calling Virginia Coady "a shit mother" in 3.04. The episode aired the night before Mother's Day.

* HolyShitQuotient: Expect every episode in Season 1 to have this but the Season 2 premiere seems to top this off with [[spoiler: DYAD not being the ones to kidnap Kira, Helena being alive and Delphine going against Cosima's wishes and dropping off a vial of her blood to Leekie.]] And then the subsequent episodes in Season 2 [[SerialEscalation just take it further]]. This dropped off some in season 3, but is back in full force with season 4, which has a rather impressive sequence of {{Wham Episode}}s, especially towards the end of the season.

* JerkassWoobie: Even though she [[spoiler: kidnapped Kira]] and even at one point tried to [[spoiler: stop all research going into finding a cure for Cosima]] you can't help but feel sorry for Rachel when she starts becoming more and more unhinged over the season in her determination to try and find out what makes Sarah so special from the rest of the clones. Turned UpToEleven in the season 2 finale, when [[spoiler: Ethan Duncan ''poisons himself and dies'' right in front of her.]] It's also pretty difficult not to feel sorry for her in the season 3 première when [[spoiler:Delphine ''outright tortures her'' while she's suffering from apparent mental trauma. Of course, the revelation later in the episode that Rachel was planning to have several of the main characters killed probably erases any sympathy this scene gained her with the audience.]]

** Saying [[spoiler: sister]] in Helena's accent: [[spoiler: ''sestra'']].

** #[=SaveCosima=] - in response to [[spoiler: Cosima's worsening autoimmune disorder]].

** Comparing Alison to [[Series/{{Weeds}} Nancy Botwin]] or [[Series/BreakingBad Walter White]] after she [[spoiler: starts selling drugs to finance her campaign for school trustee.]]

** Rachel's character arc since she was introduced seems to have driven her closer and closer to the MoralEventHorizon ([[spoiler:lying about having Kira in an attempt to manipulate Sarah into compliance, for example]]), but if she hadn't crossed it by 2.05, she unquestionably did so in that episode; her reaction to [[spoiler:Daniel]]'s death is to frame [[spoiler:Felix]] for a murder Daniel committed and use this to blackmail the rest of the clones. Oh, and she basically rapes [[spoiler:Paul]] at gunpoint too. [[spoiler:When Helena plots to kill Rachel at the end of the episode, quite a few viewers will likely be rooting for Helena to succeed, even though her doing so would have disastrous consequences for Felix. Of course, she only crosses the line further when she poses as Sarah and kidnaps Kira and [[ReassignedToAntarctica reassigns Delphine to Germany]] purely to spite her and Cosima.]]
** Helsinki -- [[spoiler: years ago, Ferdinand and Rachel murdered six clones along with their family and friends.]]
** Dr. Coady [[spoiler: sending the CASTOR clones out to seduce and/or sexually assault women to use them as test subjects in developing a sterility-inducing biological weapon]].

** [[spoiler: Rachel and Paul]]'s sex scene in season 2; as rapey as it is, it's also weird and unsexual.

** Be sure to have a barf bag handy in 4.03 when [[spoiler: the Hendrixes exhume Leekie's rotting corpse]].

** It's extremely unsettling how far-reaching [[spoiler: the Neolutionists]] are. And the whole concept of monitors -- your friends, family, and/or lover might be spying on you. Imagine [[spoiler: a group of scientists capable of watching your every move, performing tests on you in your sleep, or [[AdultFear taking away your child]]]] because someone you trust is working for them.
*** [[spoiler: Donnie's storyline in the second season shows that the reverse is true. You could be tricked into enabling the harm and dehumanization of someone you love and be completely in the dark about it.]]

** Paul's [[spoiler: HeroicSacrifice and AnguishedDeclarationOfLove to Sarah at the end of 3.06]] instantly won him a lot of fans.

** Ferdinand is an interesting example of a character who started off as something of a EnsembleDarkHorse before later becoming largely reviled by the fanbase. Though initially he was seen as a quirky fan favourite for being played by the hugely talented James Frain and being great [[EvilIsCool comic relief despite his villainous status]], this all changed when [[spoiler: he murdered MK]]. Add that to some squicky interactions with his love interest Rachel and [[spoiler: the murder of Mrs S]], and you got a character most of the fandom really despise. [[spoiler: on Tumblr, many people were actively celebrating his death in 5x08]].
* ShipsThatPassInTheNight: Delphine and Sarah haven't interacted on screen yet but hold a fair-enough amount of supporters for their ship. [[spoiler: In 2.01, they actually kiss, but Delphine thought it was Cosima. They do get a lot of screentime together in 3.01.]]

** Felix and [[spoiler: Tony]] kissing, given that [[spoiler:Tony is a FTM {{transsexual}} clone of his [[NotBloodSiblings adoptive]] [[BrotherSisterIncest sister]], and looks and acts almost exactly like her]]. Even Felix seems a little freaked out by it.
** The [[spoiler: Prolethean]] storyline from season 2 is full of this, but the worst instance has to be [[spoiler: Hank impregnating his daughter Gracie with Helena's children]]. And a lot of other disconcerting things happen at that ranch as well.
** Early on in the season 3 premiere, we get a ''lovely'' shot of [[spoiler: the pencil being removed [[EyeScream from Rachel's eyeball]].]]
** [[spoiler: The Leda and Castor clones being siblings means Rudy kissed [[SurpriseIncest his long lost sister]]]].

** Episode 4.05 gives two instances -- the baby with ''severe'' [[BodyHorror birth defects]] and [[spoiler: ParentalIncest between an adopted mother and son pair]].

* VisualEffectsOfAwesome: Any scenes where there are more than one clone featured are done brilliantly to the point where you forget that all of these characters are being played by the same woman. [[spoiler: They get four clones on screen at once in the Season 2 finale ''and'' both the first and last episodes of Season 3, and as usual, it's seamless.]] Series 5 takes it UpToEleven with a scene where [[spoiler:Sarah and M.K. have a long conversation filmed as TheOner, with both of them freely crossing to each other's side of the screen.]]

** Sarah - Unable to be with her daughter whom she loves. [[spoiler: Watching her real birth mother die after a lifetime of wondering what she was like. Now she and Kira are on the run from both the religiously zealous Proletheans and the cold, calculating Neolutionists.]]
** Alison - [[IJustWanttoBeNormal Just wants to be normal]], is unable to cope with her life being a science experiment and [[spoiler: her husband who she really does love is actually her monitor. Now she has to live with the guilt of letting her friend die.]] Arguably the last of these brings her into JerkassWoobie territory, though she'll probably get better. [[spoiler:Then her guilt lead her to drink herself into rehab, where she was {{blackmail}}ed by her husband, manipulated by Vic, and spied on by Angie.]]
** Cosima - Feels heart broken finding out Delphine search through her things and revealed to Leekie she was in contact with the others [[spoiler: and has now developed an IncurableCoughOfDeath]].

** Krystal was assaulted and almost kidnapped, and the only people she can talk to are her customers. [[spoiler: Then she really was kidnapped by Nealon to be used as Rachel's body double. She desperately wants to learn why she's such a WeirdnessMagnet, but she's deliberately kept LockedOutOfTheLoop by the other clones because they think this will protect her. It's not entirely clear whether this is actually working, especially since she turns out to be a pretty competent detective, although when she finally is let in on everything in the season 4 finale, her initial reaction to being told she and Sarah are clones is disbelief]].

** Gracie. You can't help but feel sorry for the poor girl whose parents are religious-nutcases and are too focused on [[spoiler: Helena]] to care about their daughter. Especially more when she finds out that if they don't get [[spoiler: Helena]] back, then she'll have to be the one to [[spoiler: carry the eggs they took from Helena -- which is a lie, as they forced her to do it anyway after Helena was recovered.]] She might also count as a JerkassWoobie. [[spoiler: Things only get worse for her in season three. After learning that her husband was a clone, she goes crawling back to her abusive mother, only to later be kicked out for having a miscarriage. Now it seems Mark left her with some bizarre STD which left her sterile, although she ultimately confirms that she never wanted children in the first place.]]
** [[spoiler: Ethan Duncan lost his family because of his and his wife's genetic experiments and now he lives in fear for his life. All he wants is to be with his daughter, but he hasn't seen her in twenty years because she thinks he's dead. When they finally reunite, she refuses to let him reconnect with her as she insists they keep their relationship "professional".]]

* AlasPoorScrappy: Fans were caught off-guard by how heartbroken they were when [[spoiler: Paul pulled a HeroicSacrifice to get Sarah out of the Castor base and destroy Coady's research]].
* AlasPoorVillain:
** [[spoiler: Fans took Helena's death particularly hard. Subverted in that she's not really dead, but just watching Sarah shoot her is still painful.]]
** While she's more of a nuisance than a villain, it's hard not to feel bad for [[spoiler: Aynsley, especially since she was an innocent bystander.]]

** Rachel's devastating situation in Season 3: [[spoiler: Suffering from brain damage and aphasia to the point of barely being able to form words, and being at the complete mercy of her former colleagues as she has become just one more lab rat to them has earned her sympathy from many fans.]]

** Many fans weren't pleased with the revelation in the season 2 finale that [[spoiler: male clones outside of Tony exist]] but many are also not against it, curious to see where the show will go with such a reveal.

** Felix and [[spoiler: Tony]] kissing, given that [[spoiler: Tony is a FTM {{transsexual}} clone of his [[NotBloodSiblings adoptive]] [[BrotherSisterIncest sister]], and looks and acts almost exactly like her]]. Even Felix seems a little freaked out by it.

* TheyWastedAPerfectlyGoodCharacter: Tony the transgender clone offered a fantastic opportunity for Maslany to stretch her acting muscles even more, as well as giving representation to a seriously overlooked group. Instead he leaves after a single episode without much characterization being established. On the plus side, the creators have said he will be back in season three. [[spoiler:He never showed up.]]

** In the season 2 finale, [[spoiler: we discover there ''was'' a male clone base, the Castor to Sarah's Leda. Some fans were disappointed that Mark, a Prolethean who lacks personal connections to any of the Leda clones, was a clone rather than a more prominent male character like Felix or Art. The creators said they considered it this but decided it was a bit pat and obvious, as well as not fitting with their other ideas.]]

* TheUntwist: Was the clone thing really worth saving until the third episode? To be fair, it's not entirely clear it was intended to be a twist; it was heavily foreshadowed by the end of the first episode.

** All the women who were [[spoiler: unknowingly sterilized by Coady via the Castor clones' sexually transmitted defect. They were being used as lab rats in the making of a biological weapon.]]
