Note: While some spoilers are marked below, not all of them are. Tread carefully. These tend to be in rough chronological order, but no guarantees.
- Not to mention there were a few clones in both America and Europe, so there can be more clones than we think.
- Confirmed in the season 2 finale. The group of clones is male and includes Mark Rollins. It's fairly clear that the second batch was in development before the Duncans were removed from the situation.
- Confirmed with more LEDA clones in season four - we meet Mika, and Kira talks about more they don't know about.
- The series finale ultimately confirms that there are some 274 Leda clones out there. And presumably beyond those, there were also the Helsinki clones and presumably others before they were killed off.
- Is an agent of whoever made the clones, trying to get rid of the experiment
- Jossed.
- Is an agent of opposers to whoever made the clones, trying to get rid of the experiment
- Confirmed, though Helena's group brainwashed her into believing she was the original.
- Has gone rogue after learning about the experiment, trying to get rid of the experiment on her own
- Jossed.
- Is the original, either having just learned about the experiment or knowing for some time and having a guilty conscience, trying to get rid of the experiment because she feels responsible.
- Jossed.
- As Helena is her twin, it's possible that she can have children as well.
- Not quite confirmed yet, but that seems to be the line of thought by the new sect of Proletheans. A surrogate mother is currently pregnant with half of Helena's DNA. Whether or not the child will come to term has yet to be seen...
- This appears to be confirmed, as it's been stated the reason Sarah and Helena are fertile is because their birth mother fled before Dyad could do whatever it was that made the other clones infertile.
- Helena ultimately becomes pregnant and ultimately gives birth towards the end of the series, so it's safe to say this hypothesis is confirmed.
- Beth couldn't have kids either, according to Paul.
- Alternately...
- Seems unlikely, though, as Sarah was born within a month of the others. One would think the original would be older.
- Although, Sarah is (presumably) the only fertile clone, and it's worthy to note that when Sarah asked Helena if Helena thought herself to be the original clone, she didn't actually answer. There's also that Helena didn't want to kill Sarah after learning that she wasn't Beth.
- Jossed in Season 3: Mrs. S's mom is the source of both the Castor and Leda clone lines.
- It is possible that she was trying to cover up the real reason why she killed Maggie Chen. That said, it was weird how she was completely unfazed by seeing Sarah right in front of her, even if she already knew about the clones.
- Confirmed, more or less, in season 4. She was blackmailed into her "suicide".
- Jossed.
- Confirmed at least partially: Each clone has at least one distinctive genetic marker, probably so the Neolutionists can tell them apart.
- In addition, the cloning experiment was called "Project Leda". According to the other wiki, Leda of Sparta was seduced by Zeus in the form of a swan, then gave birth to a clutch of eggs... one of which grew up to be Helen of Troy.
- Plus she exhibits a lot of special abilities and talents (her intelligence, in one scene she's practicing piano, the doctors looking surprised at something on her charts and her instant recovery after being hit by a car, her perceptiveness when meeting Allison faking as her mom and her perceptiveness at meeting Helena and asking her 'what happened to you?'. She's a very smart and independent child who might be special for more than one reason.
- Jossed. The clones were intentionally made infertile - Sarah is an outlier.
- On the other hand, by season 5's version of the story, Kira is the ultimate goal of the cloning experiment, if only by accident. This is claimed to be what they were trying to achieve. Though what that has to do with "establishing a baseline" is entirely unclear.
- If there is something cloning-related wrong with her...
- Seemed to me that it was a simple matter of Tomas treating her like crap and not feeding her enough and definitely never giving her anything sweet.
- It could also be a sign of opiate addiction ... sugar can sometimes alleviate the early symptoms of withdrawal.
- Confirmed for Cosima in "Endless Forms Most Beautiful", as she starts coughing up blood.
- Jossed. She is just another clone.
- Confirmed. Her internal organs are reversed, so her heart is on the other side of her chest.
- Jossed. But close. The original is Siobhan's mother. And in a twist of genetic chimerism, she's the Castor original as well, thanks to DNA absorbed from her male twin in the womb.
- Jossed. Sarah and Helena's birth mother escaped before they could be made infertile.
- Jossed, she says in season 5 she grew up on a boat and has little contact with her parents because they are often remote, but they do care about each other
- Jossed: She was taken by Ms S herself. And safeguarded by one of her former associates from back in her revolution days.
Allison - Helena - Beth ...
Sarah - Rachel ...
As we saw from the finale, Cosima is sick, much like Katja was.And if you think about it, Allison is going down a slightly abnormal path, from a psychological standpoint, much like Helena.Additionally, from what we hear about her, Beth was withdrawing emotionally, and she committed suicide.Sarah and Rachel are both savvy people, even though they are on opposite sides of the fight. They are both seemingly in charge of the situation, slightly like a batman gambiter.
Allison and Helena's parallels are frightening when you think about the fact that Helena was pushed towards insanity by the many many years of abuse, while Allison is living a supposedly perfect life, yet she is finding herself increasingly paranoid and violent.
- I find it unlikely that he was a traitor before the first season, however he is a perfect candidate to become this: He is very close to Sarah (not to mention the other clones); Has a criminal record and does ilegal activities for finacial blackmail; Could be emotionally blackmailed to cooperate because of Sarah, Kira, Siobhan and even the other clones.
- However, he was awfully fast to implicate Ainsley while Allison and Sarah were interrogating Donnie...
- Doesn't that make him more suspicious, considering that Aynsley was not a monitor after all?
- However, he was awfully fast to implicate Ainsley while Allison and Sarah were interrogating Donnie...
It's hard to believe they succeeded to clone humans in 1984 because the original Mac was just being sold along with the Commodore 64 and the Cray Super computers (cost $33 million) were as fast as a 1995 Dell Dimension. It would take 1 MILLION of those Cray II's to calculate a fold in a chromosome strand in a day at a cost of $33 TRILLION. The human Genome Project was just starting in 1984 and wouldn't be completed for decades (and still has a few uncharted regions).
This is a sci-fi show and for them to have cloned humans in 1984 I'm thinking they had alien help. Maybe a global conspiracy that would need the resources of the USA, Soviets, Germany, Japan, and other countries with vast hidden sections in their budgets to pull it off.
- The problem is that half the world hated the other half at the time. Why would they work together, share technology (arms race anybody), and pool their money together?
- From the remaining members of the Clone Club, she seems to be the most unhinged and unstable with the whole situation, is the quicker to complain about anything (a sign of how she doesn't see any way to control things). She also the one with has least amount of skill to contribute, she herself said that 75 grand was her way to give any sort of help, and that still is a very passive way of providing.
- And besides Sarah, she is the only clone with children she clearly cares for. With her monitor this close to them, she might be more easily swayed or blackmailed than the others.
- Semi-confirmed? She spends most of season 2 dealing with the guilt of Aynsley's death and she eventually gets put in rehab by Donnie for her pill and drinking problems. She gets better for the most part eventually.
- Her suicide still seems a little too weird (it is hard to say if it is out of character), despite the situation.
- Confirmed in season 4. The première is a Whole Episode Flashback focussing on Beth, but it ends right after Maggie Chen’s shooting. Later episodes reveal more of her life up to her suicide, and it's ultimately revealed that she was blackmailed into it.
- The "Beth" we see jump is dressed up in a skirt-suit and heels with her hair in an updo, which does not match Beth's usual style from photos and videos. There's also the question of of how she got to the station when her car was still parked at her apartment.
- Season 4 will have Sarah exploring further on Beth's own investigations on the clone conspiracy given how she was Where It All Began which may or may not address this point.
- Ultimately Jossed. Season 4 looks at Beth's life in several long flashbacks, one of which takes up most of the first episode. She's definitely dead, though she was blackmailed into her suicide. The scar may have been a simple continuity error.
- Time seems to be passing a little faster in season four. Since there's only going to be one more season, I would doubt they'd change her now.
- I thought the show made it pretty clear she was with Vic during that time conning people with him. And then when she wanted out of it, she stole cocaine from him and returned back.
- Vic could be in on all of it.
- Jossed, presumably. There's no reference to anything like this occurring at any point in the show.
- Jossed. Her organs are reversed, which is why she survived.
- You know, considering Helena survives beatdowns, being stabbed with rebar, can drink huge amounts of alcohol without it touching her... I think there's something to this. Even being shot in the chest on your non-heart side is pretty traumatic. Alison also seems to be stronger than the average woman her size, so this might only be semi-jossed.
- Could still happen, but your reasons are Jossed as she's joined Clone Club in full.
- Ultimately Jossed completely. She survives through the finale.
- Jossed. At least for now, but the character hasn't shown up in a while, and Alison's on a better track now.
- Jossed. Project LEDA was the name of the cloning project itself, in which all the clones were meant to be infertile (and Sarah was an outlier).
- At least half-Jossed. Rachel's father is still alive. Her mother was killed by Leekie.
- 3x10 Jossed the other half; Susan Duncan is still alive.
- Jossed. Donnie was recruited in college to be Alison's monitor by Dr. Leekie as part of a fake sociology experiment.
- Jossed. Donnie genuinely loves Alison.
- Jossed: As of 3x04 Gracie suffered a miscarriage. However, see the most recent as of July 2017 episodes of season 5.
- Jossed. The titles are from Eisenhower's speech about the military industrial complex.
It was also explain Sarah's Improbable Aiming Skills after literally minutes of practice and how Helena is such a terrifyingly competent assassin despite being trained to kill by nuns.
- Jossed, pretty much.
- Confirmed, but its only a few weeks long.
- Confirmed. Though she gets a prosthetic eye at the end of 3x08, so it doesn't last long.
- Sort of Jossed, but sort of confirmed. Not Helena's embroyos (those were destroyed), but Sarah's eggs fertilized by a Castor clone's do create zygotes that can be used to create the cure.
1x03 is a very crucial episode to this theory, as it reveals that clones have identical fingerprints... yet the fingerprints of Sarah/Katja didn't match Beth! It's also never been stated whether Helena's prints match—she was wearing gloves in that episode.
If Beth were merely another clone, then her prints would match Sarah/Katja. However, if she were a twin, there's a 1/2 chance that her prints would not match! Beth was then replaced by her twin (who believed she was a separate clone), and the twin proceeded to use Beth's identity, shoot Maggie Chen, and commit suicide with the intention that "Elizabeth Childs" would die. Meanwhile, the real Beth took the identity of (or, if dead, was identified as) her twin.
- IRA or some related organization would make most sense. Siobhan is an Irish name and she tried to phone in a car bomb against DYAD. Car bombs were a frequent tactic employed by Republican Paramilitaries during the "Troubles" in Northern Ireland.
- The Birdwatchers apparently started out as a group of freedom fighters somewhere in Ireland (possibly Northern Ireland), probably meant to mirror the IRA and similar organisations. Siobhan is confirmed to be Irish, and she certainly speaks with an Irish accent (which is also a case of Actor-Shared Background since Maria Doyle Kennedy is also, as one might expect with a surname like Kennedy, Irish; Siobhan's background may have been written to allow Kennedy to use her natural accent). That said, Mrs. S. has certainly espoused left-wing politics at certain points in the series - for instance, by gently chiding Sarah on the grounds that, while Sarah inherited her love of punk rock from Mrs. S, she didn't inherit the political thinking - so it's reasonable to conclude that Mrs. S may be still a communist, anarchist, or socialist.
- Confirmed in 3.05.
- Jossed. Sarah gave birth to Kira probably around ten years ago, and Rachel was made infertile before birth.
- The show doesn’t officially bring the nature versus nurture debate into the clones’ personalities, but season 3 does indeed reveal that the CASTOR clones are mostly quite similar to one each other. Mark is the clear outlier, and that appears to be due in no small part to falling in love with Gracie.
- This is further explored in season four with the case of Ira Blair, who is completely different from the other Castor clones, due to his wildly disparate upbringing.
- Jossed. They're brother and sister, not son and mother. Or, more accurately, twins. Or, depending upon how you define it, the same person, since the original was a genetic chimera who absorbed her twin brother in the womb.
- Semi-confirmed. Not with Deangelis, but Donny is arrested for dealing in season four.
- Semi-confirmed, but not completely. While only one of the CASTOR clones we've met survived the season, there seem to be more out there who will most likely play a part in season 4.
- The only Castor clones to appear in the last two seasons are Mark Rollins and Ira Blair, the latter of whom is one of Susan's assistants and is completely different from the other Castor clones in both background and temperament, having not had a military upbringing. If there were any other Castor factions, they don't play a part in the plot.
- Jossed. That scene was from the aftermath of Helena (who was disguised as Alison) killing Pouchy and his cohorts. They had the tremendously brilliant idea of threatening Alison's kids in her presence.
- CONFIRMED in the season 3 finale.
- Makes sense, since Delphine's "What will happen to her?" remark suggests the shooter is someone else who knows Cosima well.
- Jossed. Delphine was shot by Duko.
- Jossed. It's new technology.
- Beat me to it. I find this very likely as she was set up as a major player, and then she just dissapeared for a full season. I don't think she was even referenced. Even if she's not the shooter, I think she is either allied with Neolution, or being held/under strict watch by them.
- But see above. There's no evidence Marion has seen Cosima, much less cares for her enough for Delphine to ask her about it.
- Jossed. Delphine was shot by Duko.
- He'd be the last character you'd imagine doing anything like that.
- The echoing footsteps after the shooting sound hard and loud, not like what you'd expect Shay's to sound like
- But he cares very much about Cosima (And see next)
- Jossed. Delphine was shot by Duko.
- Delphine had to know that taking Rachel's position makes it more likely that she will be killed, especially now that she knows the truth about Neolution. So why not stage her death before it happens for real, and go into hiding like so many other characters in the series did at one point?
- She's shot in the abdomen, not the chest. It would produce a lot of blood, enough to make it look as if she were murdered if her body weren't also there. But with prompt care she could survive the wound and recover.
- The sound of the gunshot also seems unusually weak for a firearm in an empty parking garage, even one with a silencer. Maybe it's not really a firearm she was shot with?
- And why go to a parking garage, such an obvious place for an attempt to be made on your life, if you expect someone to try to kill you? Unless you've already planned it with someone else to make it look like you were killed.
- And yes, she could fool the Neoloutionists, who seem not to know exactly what happened to Leekie (who, in fairness, they were probably going to kill off themselves pretty soon anyway).
- 4x07 indicates that there may be something to this theory. When Krystal saw Delphine get shot, the latter was still alive and got carried away by an as-yet-unknown party. It's not clear whether Delphine is responsible for this herself, but it does indicate that she very well may still be alive.
- Semi-confirmed. Delphine is alive, although she did nearly die, and Duko was trying to kill her, but she doesn't seem to be in control of who knows she's alive.
- Or, after defeating the Proletheans, the clones, now in control of Dyad, will have a showdown with the Rossum Corporation.
- Jossed, though they're arguably part of a Big Bad Triumverate with Neolution and Coady's military faction. Regardless, by far the most screen time is devoted to Neolution, and to Westmoreland in particular.
- Jossed. She doesn't appear outside of a flashback in season 4.
- Beth - Law: Upon her suicide she introduces Sarah, a longtime criminal and con artist into the Clonespiracy.
- Rachel - Corporations: Upon her capture by Neolution DYAD's control is virtually relinquished to Neolution and Delphine's assassination cements this.
- Helena - Religion: Takes down the Proletheans in a Heroic Sacrifice.
- Allison - Social Obligations: Clones lose trust of each other and takes an "every man for himself" approach.
- Cosima - Academia: Project LEDA becomes public scientific knowledge.
- Sarah - None: (This seems to imply she is the fittest of them all)
- Her accent is certainly suitably Nordic-sounding, and both characters are stated to be skilled hackers.
- Confirmed! Very elaborate plot point upon this in Episode 4 of Season 4.
- Seems to be confirmed as of 4x08 and the previews for 4x09. Of course, there's no telling whether she also has ulterior motives...
- Ultimately confirmed, though she spends awhile in the Heel–Face Revolving Door first. Discovering that Westmoreland has been manipulating her for most of her life seems to be what permanently solidifies her alliance with the Leda clones, though she also seems to experience a genuine Heel Realization at some point in season 5. Even before then, Ferdinand's behaviour in the first half of season 5, which is far more ruthless than hers by that point, causes a case of Everyone Has Standards when she breaks up with him and fires him as a direct result of said ruthlessness, so it's possible that the other Leda clones' actions had already been rubbing off on her by that point.
