"Lost and Found" is the fifth episode of Season 2 of Dark.


In 1987, Ulrich seizes an opportunity. The kids return to the cave with the time machine, and Jonas learns of a loophole that could change the future.



The older Jonas and Martha are making love but mysterious black strands form veins in her abdomen, bursting out of her navel. Jonas then awakens from this nightmare, panting.  


The younger Jonas awakens in a strange room and is startled to find Adam sitting in a chair observing him. Adam tells him that people are repelled by those most similar to themselves. Jonas replies that he simply wants to know how to get home. Adam tells him to get dressed. His clothes have been laundered and neatly folded.

After doing that, he asks Adam why he is there. Adam tells him a man lives three lives: The first ends with the loss of naiveté, the second with the loss of innocence, and the third with the loss of life itself. He will turn into him. Jonas shouts he doesn't have time for this. He must return to his time as he has seen all the graves of his loved ones. Adam tells him he has plenty of time: it is 1921, and he has 99 years.

Jonas asks Adam whether he knows everything that will happen. Adam says he knows of wars and scientific discoveries, and what investments to make, but he does not know what other people will do. The younger Jonas asks him if the future can be changed. Adam replies that it took him 66 years to discover a way to leave this hell.

Jonas asks Adam about Sic Mundus and the new world, asking if they are a religion. Adam says they are the opposite of that: they are the enemy of God, having declared war on time. They are creating a new world without time and without God. Adam says the God mankind has prayed to is nothing but time itself—time is not compassionate, our lives trickle away and death is inevitable.

The entire universe is a giant knot from which there is no escape. Jonas asks him if he has already had this conversation? Yes, he has asked that very question and wondered how he could ever say the words that his older self said to him, that he could not understand how he could ever want what he wanted. But 66 years later he does. There is a way out of this senseless futility. Jonas asks him why nothing ever changes? Adam tells him he could not become who he is without being who Jonas is first.


On June 25, 2020, two days until the apocalypse, Katharina is looking at the school photo with Mikkel in it. Martha and Magnus come downstairs. Katharina tells them that there is something they need to see but they say they have to go. Martha lashes out at her, demanding to know why all of a sudden she wants to speak to them when she has ignored them for months. Katharina attempts to stroke Martha but she rebuffs her and says they no longer need to talk. They both leave.

Aleksander is on the phone asking why Clausen is so interested in the power plant and why is he really there. Regina announces that Bartosz is missing, and his bed was not slept in. Aleksander thinks he must have gotten back together with Martha, but Regina says no one is answering there. She asks Aleksander to tell her everything is okay, which he tells her—unconvincingly.


Claudia looks at a newspaper article concerning the death of her father Egon on 26 June 1987 (the next day). Her assistant comes in to remind her that the French delegation is waiting for their meeting, but Claudia tells her to reschedule and leaves.

She goes to visit Egon. He tells her it is a long time since she visited him. He tells her he is proud of all her accomplishments, and that her mother would be too. Claudia becomes emotional. She gets up to leave, telling him he should move in with her and Regina, so he would not be so alone, suggesting tomorrow. This surprises Egon, who says she is acting as though he is inches from death.


Katharina goes to the Kahnwald house, looking for Jonas. Hannah tells her he has disappeared. Katharina asks how she can go back in time to see Mikkel, as Hannah told her she did. Hannah says that Jonas has a "time machine," but has taken it with him. Katharina notices pictures of Michael and remarks how he was always there, right in front of her. She then accuses Hannah of having slept with both her husband and her son and always wanting everything that was hers, like a parasite. She asks if Ulrich ever told her he loved her, as he would always choose her.

They are interrupted by a knock on the door. It is Clausen, who has come after Hannah was not home for their appointment. He finds it hard to believe a woman whose son is missing would miss that. He is surprised to see Katharina there. He shows her the sketch of the Stranger and asks if she has ever seen him. She says she has not, and leaves. He then asks Hannah, who also denies recognizing him.

Clausen tells Hannah that he doesn't believe anyone in town is telling the truth; everyone is hiding something. He just isn't sure whether they are hiding the same thing or all have their own secrets. He asks if Aleksander Tiedemann is still paying her, even though she no longer is his physiotherapist. She says that Aleksander helps out with money because her son has disappeared. Clausen looks at an old picture of Ulrich, Katharina and Hannah as teenagers and says it is remarkable that Katharina appears so understanding of her affair.

The older Jonas breaks into the empty Nielsen house and walks into Martha's room. He sits on her bed and places the St. Christopher medal on it.

He then meets Charlotte, who asks him who Noah is. Jonas says he is a traveler and Adam's puppet—who killed Mads, Erik, and Yasin. Charlotte asks him if he knows who her parents are. He says he does not, but that he knew H.G. Tannhaus, her grandfather, though Charlotte admits that Tannhaus was not her real grandfather, even though he raised her. She asks if he was also a traveller, but Jonas says he was just a pawn, like everyone else. Claudia used him, just like she had used Jonas, Peter, and the others, to have him build the time machine, which he opens. Charlotte tells him he knows what will happen in the future, which he affirms.


Claudia goes to visit Bernd Doppler at his palatial home and says she has checked the data and found it to be normal, so what really happened to cause the incident at the power plant? He shoves a binder across the table to her, saying he knew she would refuse to let it go; the binder contains the full results. She looks through it and says the values make no sense. He replies that the tests always came back the same, matching calculations of Englert, Brout and Higgs in 1964. Claudia knows it as the God Particle: the particle that gives all things the mass they have. She says this is sensational, such a discovery should be made available to everyone. Doppler, however, tells her that it is sometimes better to let sleeping dogs lie. The nuclear plant is his only legacy; he wants his name and the plant kept secret, at least until his death.

Claudia meets with a technician in her office, and asks him to test a sample in secret. He asks what it is, and she replies that if it is what she thinks it is, it will change their understanding of the world forever.

At the psychiatric facility, (the elderly) Ulrich Nielsen looks at the photo of Mikkel that Egon gave him, as a nurse enters with a snack. Ulrich comes from behind him and smashes a bowl over his head, knocking him unconscious, and steals his keycard, which he uses to unlock the door.

He goes to the Kahnwald home and sees Mikkel sitting outside. Mikkel sees him and asks if he is all right, but Ulrich is overcome with emotion.

Mikkel brings Ulrich a glass of juice, and tells Ulrich he looks familiar. Ulrich says he has waited 33 years for this moment. He turns his glass over and repeats Mikkel's words "the question isn't how; it is when," asking him whether he recalls this. Mikkel nods and they hug each other, Ulrich weeps, while Mikkel calls him "Papa".

At the hospital, Ines opens up the medication cupboard, looks around and seeing no one watching, takes some pills and puts them in her pocket. Another nurse walks out and sees her with the cupboard open. She pretends she has to take more Iodine. She asks Ines whether she has heard about the supposed child murderer escaping from the asylum.

Ines returns home, looking for Michael, but there is no sign of him. She sees the door ajar, and two cups on the table. She calls Egon, saying she is worried the man who broke out of the asylum might be involved. Egon says he will notify the station and will come by to pick her up, as he has an idea where they might be headed.

Mikkel and Ulrich run through the forest as police cars arrive, sirens wailing. They reach the entrance to the cave just as the police do, with Egon and Ines close behind. The police fire warning shots and tell Ulrich to let go of the boy. He tries to tell them he is his son. He lets him go, vowing to come back and take him home, as lnes runs to him and hugs him, though he is more focused on his father. Seeing Egon, Ulrich says it is all his fault, and next time he will kill him.

Ines carries Mikkel home. She makes him hot chocolate, adding contents of medication into it.

Ulrich is returned to the asylum, drugged and restrained.


The teenagers return to the Winden Caves and are observed by Noah. Bartosz is still tied up there. They ask him what is going on. He says he cannot tell them and even if he did, they wouldn't believe him. Franziska tells him that the human body can survive three days without nourishment, and they all prepare to leave. Finally, he tells them it is a time machine. Magnus does not believe it, but Martha tells Bartosz to show them how it works. Bartosz says he needs a phone. Martha hands him hers. This activates the device.

The teenagers emerge from the cave and realize the landscape is different, the chair is missing. Bartosz says he didn't believe it at first either, but Noah told him what would happen before they happened: Martha would kiss Jonas, his mother would get cancer, Jonas would disappear but he will soon return. Franziska says Elisabeth knows Noah. Magnus scoffs and leaves, the others following. Bartosz asks Martha if she trusts him. She does not answer and goes to join the others.

They emerge from the forest and come to the bus stop. Posters advertise a 1987 concert. Police cars drive past, containing Ulrich, who recognizes his children and tells the police to stop but they drive on. Bartosz asks them if they believe him now. Martha looks at him and walks off with the others.

Charlotte returns to the clockmaker's shop and finds a picture of her as a child with Tannhaus, as well as the blueprints to the time machine. The door opens. Noah enters and introduces himself. Charlotte says she knows who he is and that he has killed the children. He tells her he hopes she will one day understand that he is only acting to try to put a stop to everything once and for all, so she won't be taken from him again like her mother was. He shows a photo of him with her as a baby, saying she had been premature but had a strong will to live. He tells her that her mother had taken the picture, and he had promised to bring Charlotte back. He had been searching for her, but she had been there the whole time—and Adam had known. He says the apocalypse is going to happen in two days, and he knows that he must end Adam so that everyone can live, not just those in the bunker. Charlotte asks him who her mother was. Noah says she loved her very much, and still loves her, then leaves, causing Charlotte to burst into tears.

The older Jonas returns home. He asks his mother whether she ever loved his father? He tells her he knows of her affair with Ulrich. He asks who she would choose: Ulrich or Papa. He tells her he thought she was the only person he could trust. She admits that she messed up everything, and Jonas says coldly that perhaps she has always done that; she needs no one, just herself.

Martha returns home and finds the St. Christopher medal on her bed.


Adam leads Jonas and shows him a God Particle that was created by him, that will send him to the day he chooses to travel to and break the 33-year cycle. Jonas now understands why he is there, so he can stop the apocalypse from happening, by stopping its beginning. Adam says the question is when is the beginning and what sacrifice must be made? Jonas tells him the day before his father committed suicide, the 20th of June, 2019, was when everything went to chaos. Adam tells Jonas that if he can prevent the suicide, then nothing that follows will occur: Mikkel will not travel back, they will never be born, but everyone else will live—including Martha. They will reorder the world.

Adam activates the God Particle, causing it to stabilize into a smooth sphere. Jonas, gas mask on, enters the God Particle.


  • Adam: Is it not peculiar that one feels the greatest aversion towards the very people who are most similar to oneself?
  • Martha: You've hardly spoken to us in months and now you want to know what we think? Look around you. We're the kids, but you've been acting like one for months.
  • Adam: A person lives three lives. The first ends with the loss of naïveté, the second with the loss of innocence, and the third with the loss of life itself. It is inevitable that we go through all three stages. You will turn into your older self, and your older self into what you see before you.
  • Claudia: I want you to move in with us. You wouldn't be so alone, and Regina would be happy to see more of you. Tomorrow would be best.
    Egon: Tomorrow? You're acting like I'm almost on my deathbed.
  • Katharina: He was always here, right in front of me. I just can't believe you slept with my husband and my son—nut you always did want what belonged to me. You're like a parasite. Did Ulrich ever actually tell you he loved you? In the end, he would always choose us.
  • Clausen: I've been here almost a week, and I get the impression no one is telling the truth. Everyone's trying to hide something—although I'm not sure

if you're all hiding the same thing or if everyone is trying to keep their own skeleton in the closet.

  • Adam: We've declared war on time, declared war on God. We're creating a new world, without time, without God. What does that mean? It means that what people have worshiped for millennia—the God who holds everything together—that God is nothing more than time itself. Not a thinking, acting entity, a physical law with which one can negotiate as little as one can with one's own fate. God is time. And time is not merciful. We are born, and our life is already trickling away like the sand in this hourglass. Death is forever inevitably before us. Our fate is nothing but a concatenation of cause and effect, in light and in shadow.


  • The recurring dream of Jonas and Martha making love is seen again, this time involving the older Jonas, who also awakens panting and sitting on the edge of his bed, as we have seen with teenage Jonas, Martha and Mikkel.
  • Hannah continues to lose the men in her life- Michael, Young Jonas, Ulrich and now Older Jonas.
  • Ines seems determined to hold onto Mikkel and prevent him from finding his family, Why is she drugging him?
  • Why would Adam send Jonas to prevent Michael's suicide, thus erasing his existence?
