Spoiler Alert: contained below are spoilers. Lots of spoilers. If you don’t want spoilers for every season of “Dark”, stop reading, get watching, and come back. You’ve been warned.

The German drama series that’s taken Netflix by storm, “Dark”, streamed its last show on June 27, 2020. The concluding episodes wrapped up the destructive events that had been unfolding over the last three seasons, with the myre of alternative dimensions, wormholes, and paradoxes becoming clear. 

From the inaugural episode, “Dark” has been a well-crafted conundrum. We’ve had flashes of foreshadowing of events, callbacks, and references that wouldn’t have been obvious the first time you watched. Kim Renfro compiled the most important details you probably missed, from the very first pilot right up to the finale.  

Scroll on for everything you need to look out for when you binge it again.  

Even the opening credits in season one, with their mirror-like effect on the titles, were an early recognition to an origin world with two parallel off-shoots.

Season One, Episode One: “Secrets” Netflix

The final season revealed to us that there are, in fact, three different worlds. In the origin world, H.G. Tannhaus invented a time travelling contraption in order to try and save his son, daughter-in-law, and their daughter.  

As that device was created, so too were a pair of other worlds; Martha’s and Jonas’, which sprouted Adam and Eva-type characters Jonas and Martha. 

The original title card for “Dark” shows us the same street across three different panels. Two streets are mirror-images, a representation of Martha and Jonas’ realities, whilst the third one symbolised Tannhaus’ original world.  

The trio of cryptic images also reflects the 33-year cycling of the mirror worlds that is set to continue.

“The Apocalypse is upon us” joked Ulrich, telling Katharina about the long queue at the bakery because of the first day of school.

Season One, Episode One: “Secrets” Netflix

Sticking with the pilot, we get a seemingly throwaway line from Ulrich, claiming “the Apocalypse” was his reason for being late to breakfast. The truth was his morning sex session with Hannah…

The detail of the Apocalypse comes up again in the second season, this time talking about the explosion at the nuclear power plant as Clausen opens the radioactive barrels.  

In the family kitchen in the Nielsen house, we see papers and photos stuck up with one looking like a labyrinth, plus a ticket with “Helge” printed on it. 

Season One, Episode One: “Secrets” Netflix

The scent of Ulrich’s sweatshirt After Katharina smells Ulrich’s sweatshirt makes Katharina suspect he’s having an affair; at the moment the camera momentarily zooms into the wall at the back of shot.  

Notice the maze type pattern on the wall – it’s a theme that gets returned to across the season and a nod towards the story of Ariadne and Thesus, that we’ll come to soon. 

Notice the ticket stub with “HELGE” is red print. We meet Helge properly later in the season, when it comes to light that he’s snatching children with Noah to test his time machine down in his lair.  

In the pilot episode Martha has already sensed that there is the parallel world when she told Jonas about her déjà vu.

Season One, Episode One: “Secrets” Netflix

“I think I’m having déjà vu,” Martha tells Jonas when they meet in the woods. “The light. The forest. As if all of this has already happened before.”

“A glitch in the matrix,” he replies.

“What?” she says.

“If the world is a simulation, déjà vu is a glitch in the matrix,” Jonas says.

“Or a message from the other side,” Martha says. “I read that somewhere.”

Remember the first episode of season three? We bet you do. In this one, creators lead us to Martha’s world and in it, Jonas is experiencing a similar version of his conversation with the alternate-version of Martha. When the existence of the multiple worlds is revealed at the end of season two, it’s exciting that the mention that their world is a simulation has already happened at the very beginning of the series – in the pilot episode. Isn’t it epic?

We hear a song on Mads’ tape deck as well as on the TV down in the bunker, plus later in the first season, too. The lyrics tie into what we see in “Dark”.

Season One, Episode One: “Secrets” Netflix

Nena’s 1984 song “Irgendwie, Irgendwo, Irgendwann” plays for the first time in season one, episode one, and it comes back throughout “Dark”. 

You’ll have heard it again as Helge drives in the last episode of season one, just before the crash with the older version of himself, and we also get it playing over the final credits throughout season three. 

The title translates as “Somehow, Somewhere, Sometime”, clearly a connection to time traveling characters across the show. Even the opening verse ties into the tragedy of Jonas and Martha:

Falling through space and time

Towards infinity

Flying moths in the light

Just like you and me

Somehow it starts sometime

Somewhere in the future

One of Mikkel’s paintings in the attic is actually a picture of a famous sculpture, called  “Laocoön and His Sons”.

Season One, Episode Two: “Lies” Netflix

“Laocoön and His Sons” is a very famous sculpture depicting agony and grief. In fact, the sculpture represents a father and his children dying, which has a connection to the generational tragedy in “Dark.” Created in the 1st Century BC, the statue group is based on a Greek myth and is currently on display at the Vatican Museum in Rome. Even though it might not be clear at the beginning why Mikkel is using this particular statue as a reference for his painting, we can definitely see the thematic connection between the idea of sculpture and the events taking place in “Dark.”

Besides the sculpture, the same episode reveals one more connection between the “Dark” and the Greek myth, particularly of Ariadne and Theseus.

Season One, Episode Two: “Lies” Netflix

Did you notice that the myth of Ariadne was mentioned throughout all three seasons of “Dark”? The very first time we got this reference was from the poster behind Martha in the above scene. Interestingly, the play version of “Ariadne” that Martha performs at her school is the same version of the play we later see a young Gustav Tannhaus reading in the 1800s. 

The hotel room of Stranger-Jonas has pictures of Theseus and the Minotaur. Digging even deeper, the publisher of H.G. Tannhaus’ was “Mino Tauros”.

Season One, Episode Two: “Lies” Netflix

Sticking with the “Ariadne” trope, we see Stranger-Jonas with lots of minotaur and labyrinth pictures on the walls of his hotel room. Cool details, and it’s mirrored in the name of the publishers of the book Tannhaus wrote.  

As you can see in the shot above, the publishing house was “Mino Tauros”.

As a marker that his body was never recovered, there’s an infinity loop engraved on Mads’ headstone. 

Season One, Episode Two: “Lies” Netflix

There’s an infinity loop on the gravestone rather than a date of death, but is it also a hint at the origins of how Martha’s and Jonas’ worlds are linked together, trapped in continuous loops?  

What seemed like an innocent misunderstanding between Hannah and Jonas was actually a revelation that Mikkel is Jonas’ father (before we all found out).

Season One, Episode Two: “Lies” Netflix

Shortly after Mikkel vanishes, there’s a dialogue going on between Jonas and Hannah in their kitchen.

“Do you think he had a secret?” Jonas asks his mother.

“Mikkel?” she responds.

“No, Dad,” Jonas says.

Sometime later they’ll find out that Mikkel is actually Jonas’ father, so if you rewatch this particular scene the misunderstanding will appear much more meaningful than it seemed from the beginning.

At school, in episode four we see the teacher reference Johann Wolfgang von Goethe, a writer who’s famed play “Faust” is linked to “Dark.”

Season One, Episode Four: “Double Lives” Netflix

Episode four sees Magnus and Franziska’s school teacher talk about Johann Wolfgang von Goethe, the German writer who gave the world his play “Faust”. It’s a tale of a man who makes a pact with the devil, offering his soul in return for power and knowledge; a fitting reference to Bartosz and Noah in the first two seasons.  

Further on in season one, there’s a scene where H.G. Tannhaus and Stranger-Jonas are talking about the number 33 and its relation to the antichrist; the age he begins his rule. Cut to Noah, stood outside Winden’s church.

Adding to the “Faust” these, Claudia loses her poodle in 1953 ad it reappears in 1986. Said poodle is called Gretchen, the love interest of the titular character in von Goethe’s story. 

The infinity loop symbol we saw on the chalkboard also has a hidden meaning, alongside with the hint the teacher provided about Martha and Jonas’ parallel worlds.

Season One, Episode Four: “Double Lives” Netflix

“Symmetry is a special kind of doubling,” the teacher says. “The repetition is mirrored along a central axis. So the repetition begins at an imaginary center point and branches off in two opposing directions.” 

While he was speaking, Franziska passed by the infinity symbol drawn on a chalkboard. Like many other small details in the series, this one also has a meaning. It actually refers to the mirror worlds and the repetitive cycle of events that are happening to people trapped in these worlds.

Episode five, season one is where we meet Noah and find out he’s from St. Christopher’s Church, patron saint of travelers.

Season One, Episode Five: “Truths” Netflix

Way before we figure out who Noah is and what he’s actually about, we get a little hint at his time-traveling story.

Through seasons two and three were shown Adam’s home that he built under St. Christopher’s church in Winden. Plus, you’ll have seen a St.Christopher necklace that becomes relevant, which we’ll get to in a bit. 

When you get round to watching season one again, it’s cool to note the little wink at the larger theme of churches and time travelers so early on. 

Ulrich and Hannah talk about a movie he loved, but it’s never actually named. The film was “The Breakfast Club,” which was only released the year before. 

Season One, Episode Five: “Truths” Netflix

In the transition from 2019 to 1986 in season one, young Ulrich says “…and then she says ‘when you grow up your heart dies.'”

For those not down with the Brat Pack movies, it’s a line from the 1985 movie “The Breakfast Club”, said by Allison, played by Ally Sheedy. Hannah says she’d be interested to see the movie, but he goes off holding hands with Katharina before he gives a response. 

“Nietzsche’s eternal recurrence” was an obsession of Charlotte’s grandfather, which we find out long before we know her connection to H.G. Tannhaus.

Season One, Episode Five: “Truths” Netflix

Episode five of the first season gives us Charlotte talking about the 33-year lunar-solar cycle and how her grandfather read about the theory of the Big Bang, Big Crunch as well as Nietzsche’s eternal recurrence. 

At that point, we weren’t to know this was all talking about Tannhaus. It’s in season two we get to know about their relationship, and even further away in the season three finale when we fully comprehend Tannhaus’ role in creating the whole mirror-worlds system.

When Martha performs her “Ariadne” monologue we’re introduced to the idea of “severing the knot”, a theme we return to in season three.

Season One, Episode Five: “Truths” Netflix

Ariadne was King Minos of Crete’s daughter, according to Greek mythology. Her father charged her with the island’s labyrinth, home to a Minotaur, and used for making ritual sacrifices.

In the legend, Theseus is a hero who comes along to the labyrinth to slaughter the Minotaur. Ariadne falls head over heels with the hero and helps him find his way out of the maze with a ball of thread. Upon his escape, Theseus runs away from Ariadne, abandoning her. 

Martha’s monologue is about her mum and when Theseus left. 

“The spinning wheel turns, round and round in a circle,” she says. “One fate tied to the next. The thread, red like blood, that cleaves together all our deeds. One cannot unravel the knots. But they can be severed. He severed ours, with the sharpest blade. Yet something remains behind that cannot be severed. An invisible bond.”

As well as being an early hint at Adam’s attempt to break the knot binding the two worlds, it’s also in reference to the last scene which offers scant hope that Martha and Jonas might find their way together in the origin world.

Note the three doors on the stage in the picture too – another detail about the three worlds the show depicts.

We hear Tannhaus explaining the importance of a third “dimension” and not just dual worlds in season one.

Season One, Episode Eight: “As You Sow, so You Shall Reap” Netflix

There’s an episode which takes place in 1986 where Tannhaus explains black holes to Jonas. 

“Our thinking is shaped by dualism,” Tannhaus says. “Entrance, exit. Black, white. Good, evil. Everything appears as opposite pairs. But that’s wrong. Have you ever heard of the triquetra? Nothing is complete without a third dimension. There isn’t only up and down. There’s a center, too.”

Even though it may seem like he talks about time travel in the past, present, and future, actually it is a major clue about the existence of three distinct worlds. 

The Raider candy bar in a TV commercial is another point with a “glitch in the matrix” that Magnus and Franziska encounter.

Season One, Episode Ten: “Alpha and Omega” Netflix

Before 1991, Twix candy bars were called Raiders in Germany, as noted on the official “Dark” website. 

We see a Raider wrapper in 2019 in Winden, an early echo of the time travelers that appear here from 1986. We know that Helge loves Raider bars and it’s probable that he was the person who leaves the wrappers during another kidnap trip.  

This begs the question, why is there a Raider advert on TV in 2019?  

We see Magnus and Franziska watching the advert in the last episode of season one, at the same time that the electric is going crazy due to adult-Jonas’s wormhole creation in the passageway of the case. Was the commercial pointing us towards the tangled worlds? 

When Stranger-Jonas looks at the random spot on the floor in the first episode of season two, it’s actually the exact place where Martha will die.

Season Two, Episode One: “Beginnings and Endings” Netflix

That one time when Stranger-Jonas looks down at the floor right after Hannah asked him what brought him here was no accident. In fact, that spot on the floor was the exact place where Martha died in the younger Jonas’ arms when Adam shot her in the season two finale. 

In the same vein, Stranger-Jonas saw Hannah with Aleksander’s gun and was shocked – he knew it to be the same gun Adam killed Martha with.

Season Two, Episode Four: “The Travelers” Netflix

The gun traveled through time with Aleksander, who’s actually called Boris, with it being taken to Winden in 1986. The gun was taken by Hannah, who kept it until it was used by Stranger-Jonas to threaten Martha into the bunker in the last episode of season two.

Eventually, the gun wound up with the Sic Mundus group, and Noah trying to use the finish Adam. Noah was shot by Martha with the same gun, it was then used by Adam to eventually kill Martha in 2020. 

In H.G. Tannhaus’ shop, we see Young Elisabeth come across a book with a foreshadowing of Adam and Eva’s twin worlds coming off the origin world.

Season Two, Episode One: “Beginnings and Endings” Netflix

Tannhaus has lots of stuff lying around, including a book about Hermeticism, which is the philosophy that’s connected to the phrase “Sic Mundus Creatus Est”, along with the picture book.

As the shot pans over the artwork, we see a man and woman blow across the pages in towards three worlds. The two flanking worlds are in the shadows with one central world, representing the origin world. 

Just a few episodes further in we see the same Sic Mundus group HQ depiction. 

Season Two, Episode Four: “The Travelers” Netflix

The creation drawing in the object of Noah’s interest when he’s talking to his older self and discussing Adam’s philosophy. 

The book young Regina and Claudia were talking about, titled “Ghosts”, was actually a story about children who traveled in time.

Season Two, Episode Three: “Ghosts” Netflix

The “Ghosts” book that young Regina was looking around the house for, while Claudia got ready in the morning, is an actual book, written in 1969 by Antonian Barber. The plot is crafted around young children who aim to change a tragic series of events by traveling backwards and forwards in time. The book occurs in the series not just by chance. As we know, young Regina was left behind by Claudia for decades when her mother started time traveling and trying to find a way to save the future-Regina’s life. 

Noticed the numbers 47, 904, 24, and 182 on a small board in the background of the St. Christopher’s Church? They appear in the same episode, when Agnes confronts Noah.

Season Two, Episode Three: “Ghosts” Netflix

24 is possibly there to represent Matthew 24 in the New Testament, with a warning from Jesus: “the destruction of the temple and signs of the end times.” At this point in the story, Noah was working for Adam, whose main aim was to destroy that entire world. 

As for 182, it’s maybe a reference to Lamech, who features in the book of Genesis, 5:28, a man who had a son when he was 182. Who was his son? Noah…

Torben Woller tells Clausen Hannah was free to marry anyone in season two. The origin world has Torben married to Hannah.

Season Two, Episode Four: “The Travelers” Netflix

“She was so pretty, she could’ve had any man she wanted,” Woller told Clausen. 

Watch it again and it feels like a foreshadowing of the detail that Hannah and Torben finish up together in the origin world. 

Adam has a famous painting in the Sic Mundus headquarters which is called “The Fall of the Damned” by Peter Paul Rubens.

Season Two, Episode Four: “The Travelers” Netflix

We’ve seen Adam standing in front of a painting by Peter Paul Rubens called “The Fall of the Damned” (or “The Fall of the Rebel Angels”) several times during the second season.

The New Testament book of Revelation tells the story of Michael, the archangel who goes to war against Satan. Satan gets cast down to Earth with a collection of other fallen angels, and continues to attempt to “lead the whole world astray”. 

It’s easy to see how Adam might view himself as a fallen angel. He was once dedicated to Claudia and the task of saving Martha, yet he ends up embroiled in the philosophy that will destroy his and Martha’s world. His whole existence is about bringing down the world, no matter what, until he finds out about the origin world from Claudia at the last moment, that is.

When we see the epic Rubens painting for the first time, Adam also reveals his true intentions to end the whole thing.

Season Two, Episode Four: “The Travelers” Netflix

During the first two seasons, Adam never reveals to Jonas that he wants to destroy both worlds. However, he tells him that he represents “everyone’s end.”  

“Don’t worry, it will come to an end. That can’t be avoided. Your end, my end. On closer inspection, it’s everyone’s end.”

In the very last minutes of “Dark”, we can fully understand Adam’s message – pretty much most of the people in Winden we’d come to know had ceased to exist. 

The “origin” was foreshadowed in a scary-as-hell sex dream that Stranger-Jonas had.

Season Two, Episode Five: “Lost and Found” Netflix

AS we enter episode five of the second season, we find Stranger-Jonas having the exact dream that we know Jonas and Martha – the one where they have sex, just like actually happens in the second world in season three. 

Stranger-Jonas’ version of the dream sees them stop and look down on Martha’s body. There’s a black blob thing that looks something like a mini God particle portal, and it’s coming from where her womb is. 

Once we got halfway through season three this all becomes clear; it’s the Unknown. The Unknown is the child of Martha and Jonas, the person who ends up fathering Tronte Nielsen and everyone else is the twisted family tree in both worlds. 

We catch a glimpse of Eva’s circular time travel device that gets used in world two in the second season. 

Season Two, Episode Five: “Lost and Found” Netflix

Check out the machine blueprint on Adam’s wall.  The official “Dark” website tells us that it’s for the “golden time travel sphere” that sends people to anywhere without a 33-year restriction as well as into other worlds.

Whilst swimming in 2019, Bartosz and Magnus joke about a woman found dead in the lake, with a later detail emerging that Katharina’s body was pulled into the lake in 1987.

Season Two, Episode Six: “An Endless Cycle” Netflix

It might be generally scary, but one of the most horrific scenes in “Dark” has to be when Katharina goes back in time in a rescue attempt for Mikkel and Ulrich. Her mum winds up bludgeoning her to death. Helene kills the adult version of her daughter before dumping the body in the lake. 

Jump to 2019 and Katharina’s children are seen swimming over her dead body with Bartosz recounting the legend of the woman in the lake who pulls people to their death. 

Helene’s St. Christopher necklace is pulled off by Katharina before she dies in 1987, leaving the charm in the sand.

Season Three, Episode Five: “Life and Death” Netflix

Skip through the decades and Jonas finds the charm; Martha puts it on a chain so it can be worn again. 

Just like the gun, this necklace has bounced around the worlds. First, Hannah received it as a present from Egon in 1954, the guy she was cheating with.

Season Three, Episode Four: “The Origin.” Netflix

Egon got Hannah pregnant and she didn’t want to keep it at first. She went to see Fran Obendorf, who’s the great-grandmother of Erik Obendorf, who was the ginger kid who disappeared in 2019. On the visit, Hannah met a young Helene and introduced herself as Katharina. 

Many years pass and Jonas finds the necklace and gives it back to Martha, who is Helene’s granddaughter as well as Hannah’s great-four-times granddaughter, because Hannah’s daughter Silja was the beginning of the Nielsen line. 

Before we all knew Hannah was Agnes’ grandmother, Egon actually asked Hannah if she knew Agnes Nielsen in season two.

Season Two, Episode Seven: “The White Devil” Netflix

The first time Hannah landed back in the 50s she met Egon and introduced herself as Katharina Nielsen. This caused him to ask if she knew who Agnes was; by then a grown adult who was living in Egon’s home. 

Later, in season three, we figure out that Hannah is, in fact, Agnes’ grandmother. The future daughter of Hannah, Silja, begins time traveling, too, and goes back to 1890, where she neets Bartosz and births Agnes.

Claudia’s dialogue with Jonas in season two held a clue about Martha’s world.

Season Two, Episode Six: “An Endless Cycle” Netflix

Claudia warned Jonas when he told her he’d rather die if it helped Mikkel, his father, to stay alive. 

“I have seen the world without you,” she said. “Trust me, it’s not what you’re expecting.” Basically, we all got the idea behind these words only in season three. We understood that Claudia had spent a lot of time in the second world – Martha’s world – where Jonas didn’t exist. That’s why she knew that the same loop of tragic events will happen there regardless of Jonas being there or not.

The letter that was sent to Clausen and said he’d find answers about his brother’s death in Winden was most likely written by the Unknown.

Season Two, Episode Seven: “The White Devil” Netflix

Clausen shares information about the letter he got with Aleksander in season two, episode seven. Even though we don’t know the true author of it, it most certainly was the Unknown – Martha’s child. 

“He that has eyes to see and ears to hear may convince himself that no mortal can keep a secret,” the letter read. “If his lips are silent, he chatters with his fingertips. Betrayal oozes out of him at every pore. You’ll find the answers concerning your brother in Winden.”

The Unknown quotes the same words, from Sigmund Freud, in season three, before Gustav Tannhaus is murdered. 

Season Three, Episode Three: “Adam and Eva” Netflix

The line is uttered by the Unknown to Tannhaus whilst in the carriage. Tannhaus intended to send a telegram that would have confirmed the existence of time travelers. To preserve Martha’s world and the rest of the events, the Unknown kills him. 

Martha used the Unknown to keep the cycle going, which makes it more than likely he was the writer of the letter to Clausen than got the power place investigated. The radioactive barrels are opened on Clausen’s orders, unleashing the God particle. 

Martha’s boyfriend Kilian, who exists in Martha’s world where there is no Jonas, was first seen in season one, participating with Martha in the “Ariadne” play.

Kilian and Martha in season three (and world two), and Kilian in season one (and world one). Netflix

The Jonas world Kilian only showed up in the scene with the play, both characters are played by Sammy Scheuritzel. 

This is another cool link that hooks the “Ariadne” play into Martha’s fate across both worlds.

In Martha’s world, she has a vision where she sees herself wearing a white collared dress while out in the woods. This is the same outfit in that she wears in world one on the same night she and Jonas first had sex.

Martha’s vision in season three, and the real Martha in season two. Netflix

Throughout world two, Martha is never seen wearing this particular outfit. This most likely means that this is a crossover vision from Jonas’ world. 

In Jonas’ world, Martha is seen wearing the exact same white dress on the night of Katharina and Ulrich’s anniversary party. That was the same night Martha gave Jonas the St. Christopher necklace and when they first had sex. 

The following day is when Jonas’ father takes his own life by suicide and when their tragic cycle begins. 

That same white dress shows up again in Jonas’ dream that Martha from world one is sleeping beside him. 

Season Three, Episode Five: “Life and Death” Netflix

In another instance, Jonas has a vision of Martha wearing this dress. However, this time he has the vision the morning after he sleeps with Martha-2 (Martha from world two) where he gets her pregnant with a child who will ultimately become the origin, aka the Unknown

Claudia overheard a major hint about the time travel loophole while listening to the radio in 2020. 

Season Three, Episode Two: “The Survivors” Netflix

During the fall of 2020, in September, Claudia walked into the abandoned police station with the radio playing in the background. It happened in world one. 

 “Scientists are still looking for an explanation for the events of June 27, 2020, the presumed origin for the catastrophe is assumed to be the small town of Winden,” the woman on the radio says. “A French team of scientists believes it possible that our world stood still for a fraction of a nanosecond on June 27, possibly causing the divergence of tidal forces.”

In the final episode of season three, we learn that Claudia has managed to use that same time standstill in order to exploit the same exact loophole as Eva, therefore being able to create a second reality that she can then use to find the origin world and be able to reverse the existence of the mirror worlds. 

The radio announcement was our first clue about the existence of that loophole.

In the year 2053, Elisabeth and Charlotte touched their foreheads exactly the same way in which they did back in 2019 when they first said goodbye. 

Elisabeth and Charlotte in season three and season one. Netflix

During a sweet flashback in season three, Charlotte and Elisabeth are seen sharing an intimate moment with one another, the same way they did back in season one. 

Eva’s extensive family tree revealed that Bartosz was actually Noah and Agnes’ father way before those events unfolded.

Season Three, Episode Two: “The Survivors” Netflix

Eva’s extensive family tree was first seen in the second episode of season three. Later on in the season, we learn that Bartosz is Agnes and Noah’s father due to some more Sic Mundus group time trickery. 

If you were paying close attention to Eva’s family tree, you may have caught on to the reveal much earlier. 

A critical mistake was also part of that family tree: Tronte Nielsen didn’t father Regina, her father was Bernd Doppler, apparently.

Season Three, Episode Two: “The Survivors” Netflix

Tronte is Regina’ father, according to Eva’s family tree. Season three tells us that Tronte was highly likely not her father, according to what Claudia says. 

Do we know who her father actually was? The official “Dark” website has a photograph that we see in the finale of season three showing Regina’s dad to be Bernd Doppler. 

Think about the scene between the grown-up Bernd Doppler and a young Claudia and how much more uncomfortable that now feels.

Season Three, Episode Four: “The Origin” Netflix

We get a flashback to 1954 in the fourth episode of season three, in which Claudia looks around 13 or 14 years old and is giving tuition to Helge, Bernd’s son.  

The adult Bernd spots Claudia in his hallway and points out that she looks pretty, smart, and “grown-up”, before giving her money that was hers anyways for the tutoring work. 

She turns down the cash with Bernd telling her, “If you really want something, then you must take it.”

This whole scene makes the thought of Bernd and Claudia having sex further down the line a very uncomfortable one. We never see their relationship dynamic in the show, only a happy family picture in the last scene in the origin world.  

Bernd Doppler gets quoted by the Unknown with words he spoke in season one.

The Unknown in season three, and Bernd Doppler in season one. Netflix

At the point Claudia first finds out about the nuclear power plant accident in season one, Bernd takes her to the radioactive barrels in the cave. 

“What we know is a drop,” he tells her, quoting Isaac Newton. “What we do not know is an ocean.”

These are the words the Unknown repeats just as he’s about the kill Gustav Tannhaus in season three, episode three. 

The words come up again when Adam speaks them to Jonas as he goes off to save the Tannhauses in the last episode of season three. Jonas pulls out the words in order to convince Marek off the bridge and saves his life. 

The Unknown has scars on his lips, watch them switch sides as he moves into the mirror worlds.

The Unknown in world one, and the Unknown in world two. Netflix

The worlds of Jonas and Martha are actual mirror images of each other, giving good reason for the scars on the Unknown’s face to switch up depending which world we encounter him in.  

When we see him in Martha’s world, the scar is on the left of his face, whilst in Jonas’ we see it on the right side. 

Martha’s cheek cut switches sides for this very same reason.

Martha in world two, and Martha in world one. Netflix

Martha has a bloody scratch on her cheek that moves about – another important example of the mirroring of the worlds. In her own world, the cut is on the right, when she shows up in Jonas’ world it migrates to the left.   

In world two, the doorways have Eva’s organization’s name, “Erit Lux”, rather than “Sic Mundus Creatus Est”.

Season Three, Episode Three: “Adam and Eva” Netflix

World one, or Jonas’ world, has Sic Mundus which is Adam’s organization. Over in world two, Eva’s one, the society of time travelers is instead called Erit Lux. 

“Erit lux” means “there will be light”, according to the “Dark” website. 

Right before Jonas dies, Eva repeats words that Adam had already said to him.

Season Three, Episode Five: “Life and Death” Netflix

In the first meeting of Adam and Jonas, back in season two, he was taught something important by his older iteration.

“A person lives three lives,” Adam said. “Loss of naivete, loss of innocence, and loss of life.”

Before Martha enters Erit Lux HQ to murder Jonas in season three, Eva speaks some very similar words. 

“A human lives three lives,” Eva says. “The first one ends with the loss of naivete. The second with the loss of innocence. And the third with the loss of life itself. Yours ends here and now.”  

As you work through the three seasons, you can chart the torment of Jonas by Adam and Eva in parallel. 

Don’t adjust your set; the aspect ratio changes when we go into the origin world. 

Season Three, Episode Seven: “Between the Time” Netflix

Not everyone will have picked up on the change, it depends on the platform you watch Netflix through. Some viewers would have noticed a change in the aspect ratio when we landed in the origin world. 

Season three, episode seven shows us the origin world with H.G. Tannhaus for the first time. You see black bars at the top and bottom on your screen, which is known as “letterboxing”. It’s a visual notation that we’re somewhere other than where we’ve been spending our time up to now. 

To blend in to 1890, Silja took dead-Martha’s clothes for her meeting with Bartosz. 

Silja and Martha wearing the same clothing. Netflix

Martha is imprisoned and presented to Adam by Silja in the sixth episode of season three. Silja orders her to strip and takes her 1800s clothes before Martha is then murdered by Adam.  

Into episode seven, and we follow Silja traveling back to meet Bartosz, where she’ll eventually give birth to Noah and Agnes. It’s not fully obvious, but her clothes are the ones Martha stripped out of as she heads into the Sic Mundus group in 1890. 

A throwback line is included in the last dinner scene, a line between Hannah and Ulrich as teenagers.

With the power down, all six dinner party attendees delve into a conversation that is a near-perfect mirror of a scene in season one.

Regina asks a heavy question: “If the world were to end today, and you only had one wish, what would you wish for?”

Regina’s question gets Katharina thinking, before she replies, “A world without Winden. Let’s drink to that.”

It’s a near-perfect repetition of what young Ulrich and Hannah say in “Past and Present” in episode three of season one.

Back then we watched Ulrich smoking at a bus stop in 1986 and Hannah rides her bike up next to him. The scene is in the middle of one of the flickering power surges Winden is known for and tells us the wormhole tunnel is in use. 

“Is this the apocalypse?” Hannah asked Ulrich. “I thought it would be a lot brighter. And louder.” 

Just a little later, Ulrich and Hannah almost match Regina’s dinner party question, “If the world ended today, and everything started anew, what would you wish for?” 

“Easy,” Ulrich said. “A world without Winden.”

With that same question and answer coming up in the final dinner scene, which we assume in the 2019 origin world timeline, “Dark” completes a loop that came right near the beginning of the story. The cycle may now have been broken by Martha and Jonas, but clearly things still collide between the two alternate worlds and the goings on in the origin world.
