Jonas meets an ominous figure. While the kids comb the cave for answers, the adults gather in the bunker to share what they know about the travelers.
Jonas (after entering the god particle: Dark Matter) lands in the middle of a field of harvest-ready grain. He buries his yellow radiation suit. He tries to walk but his leg is still badly wounded from the gunshot; he stumbles to a tree and vomits. Two men approach him and seeing his wounded neck from his almost hanging, ask what happened to him. "I just want to go home," he answers. They take him to the town to Erna, where they offer him food and a room to sleep in for a few days. He asks what year it is and is dismayed to hear it's 1921.
On June 24 (3 days until the apocalypse) Martha dreams she is having sex with Jonas, who tells her that they are perfect for each other, and not to ever believe anything else. She awakens distressed and bursts into tears.
At the police station, Clausen looks at a sketch artist's drawing of the Stranger. Torben tells him that Charlotte has called in sick. He thus asks Torben to drive him around. Charlotte has in fact gone to H.G. Tannhaus' clockmaker's shop, where she finds blueprints for the time machine. She receives a call from Hannah.
At the Kahnwald home, the older Jonas finds the box with the gun and passport. He asks Hannah why she has them. She tells him there is someone very interested that they stay hidden. He asks her why she is blackmailing someone.
Franziska goes to talk to Magnus, accompanied by Elisabeth and calls a truce. She brought her because their parents haven't been home for 2 days. Magnus suggests they go to the Winden Caves with Martha.
Jonas awakens panting. His wounds have been bandaged. The younger Noah is there waiting for him and tells him he had been asleep for almost 24 hours. Jonas tells him that he is in the wrong place. Noah tells him cryptically that he pictured Jonas to look differently, which Jonas does not understand. He sees a plaque of the Emerald Tablet on the wall and notices the words "Sic mundus creatus est". He gathers his clothes and a lantern and hurriedly leaves, passing the young Agnes, who he stares at.
Meanwhile, Clausen has gone to the nuclear power plant to question Aleksander. He tells him that he denied Ulrich Nielsen entry to the plant due to stricter security after the Fukushima disaster. He says the door to the caves was sealed shut in the 1980s as a security measure, so it would not be possible for someone to enter. Clausen tells him he finds it unusual that everyone who was born in Winden seems to remain there. Aleksander attributes this to the steady employment available at the power plant, although that will change soon.
Clausen then points out that Aleksander is an exception, having come from somewhere else, arriving in 1986, around the time that Mads disappeared. Aleksander points out that he arrived several weeks after Mads' disappearance. Clausen then asks why he took his wife's last name, which was unusual at that time. Aleksander says that as Regina was an only child, they had wanted to preserve the name. He asks what his original name was. He tells him Köhler.
At the Kahnwald home, there is a knock at the door. Jonas suggests they don't answer but Hannah goes to the door saying they must tell someone (she asked Charlotte to come). She introduces him. Charlotte realizes he is the man who Regina mentioned stayed at her hotel. She shows him the photo she found of Noah from 1921, whose identity he confirms, from Sic Mundus - the travelers. Hannah is shocked that Charlotte seems to know about this.
1987 Claudia goes to the library to learn about the history of Winden. She finds the new technology of 2020 somewhat daunting but eventually works out what to do and searches for herself, discovering that she eventually disappeared without a trace.
Torben and Clausen go to interview Hannah but she's not home. Clausen asks Torben about her. He mentions her husband's suicide, that no one understood why they married when she was pretty enough to have any man and was rumoured to have had an affair with Ulrich. Clausen wonders if Katharina was aware of that but Torben says he does not know. Torben asks whether Clausen volunteered to join the task force. The answer is a firm yes.
Jonas, Hannah, and Charlotte go to the bunker and meet with Peter. He tells them that Claudia knew what would happen and told he and Tronte what to do. Hannah cannot believe they knew about Michael, Mikkel and Ulrich. He shows her the notebook which has all the information about the missing children but the last few pages were ripped out. She asks whether Katharina knows about this. Charlotte agrees to tell her.
Claudia continues to read about Regina and Aleksander's marriage and the opening and closing of the hotel. She then searches Egon and finds an article saying he was found dead on 26 June 1987 (in 2 days). Martha says she sometimes dreams of Jonas and feels he is still alive.
Charlotte informs Katharina that Ulrich and Mikkel are still alive, but that they are not "here." Katharina is confused. She takes her to the bunker, but she becomes angered when she sees Hannah there. She scoffs when she sees (older) Jonas, who tells her he is Hannah's son and her grandson. Katharina finds it impossible to believe that Ulrich and Mikkel have travelled back in time. Martha and friends are walking in the cave when the ground begins to shake. They hear footsteps. It is Bartosz, carrying a suitcase. They demand to know what he is doing there. Magnus punches him.
Jonas heads for the caves, eventually finding the metal door marked "Sic mundus" and opens it. He crawls through the passage until he reaches a dead end. He pounds on it angrily.
Hannah tries to assure Katharina she travelled back and saw Mikkel. She tells them they have all lost their minds and leaves. Magnus opens Bartosz's suitcase and asks him what it is. He tells them it doesn't concern them. Magnus tells Bartosz that if he has anything to do with the disappearance of his brother and father he will kill him. Martha tells Bartosz they will leave him there overnight and take the suitcase.
Torben and Clausen are driving when Claudia suddenly appears in front of them and they have to swerve to avoid hitting her. Katharina goes to the school. She looks through old records of 1986 for Michael Kahnwald, who was a student and finds his class photo. She sees her son Mikkel in it and breaks down crying.
Jonas leaves the cave and is greeted by young Noah who tells him it will take another 32 years before there's an opening. Sic Mundus (the travelers) are waiting for him.
(Older) Jonas tells Peter, Charlotte and Hannah that everything is going to happen the way it always does. Adam, the leader of Sic Mundus, wants the last cycle to begin in three days, but Jonas has come to stop it. Claudia tried to do it, but in the end, became what she was fighting against.
Noah takes Jonas to the church. The older Noah enters, looks at his younger self and tells Jonas he has already made his acquaintance.
The god particle has resumed its unstable state. Elisabeth confronts Silja and with a gun pointed at her asks her what she is doing in the prohibited zone. Silja asks her what is in there and why she's been lying about it. Elisabeth answers that they say it's part of God, but in reality, it's part of the devil.
Young Noah asks his older counterpart about the prophecy and who wrote it. The older Noah says that whoever it was had already seen the past and future. He says Adam will send Jonas on the path that has been predetermined so that the last cycle will begin.
Jonas is taken deep under the church into a grand room. A heavily scarred old man enters and says to him: "You must have a lot of questions. Traveling leaves its marks on all of us, the human body isn't equipped for it, Shall we begin?" Jonas shouts that he is not here to begin anything, he is trying to end things. The old man answers that the end can't be avoided for everyone. Jonas asks him who he is? The old man opens his shirt, revealing a scar around his neck, similar to the one Jonas now has. "This isn't real," a shocked Jonas says. The old man tells him: "I am you. Everything is now in place. All that is needed is a push"
- Claudia: Tiedemann. Claudia Tiedemann. She used to run the plant. Where can I find her?
Guard: There's only one Tiedemann here. Aleksander Tiedemann, he runs the plant.
- Clausen: You're not from here.
Aleksander: No, why?
Clausen: You came to Winden in 1986, at the same time the boy disappeared. Mads Nielsen, Ulrich Nielsen's brother.
Aleksander: No, it was a bit later. A few weeks. Why does that matter?
Clausen: It probably doesn't.
- Jonas: Why do you have a gun and someone else's passport?
Hannah: It's insurance.
Jonas: What do you mean?
Hannah: Someone needs to keep both things hidden.
Jonas: You're blackmailing someone? Who are you?
Hannah: Who am I? Who are you?
- Clausen: Anything about Hannah Kahnwald?
Torben: Her husband killed himself last year. He hanged himself. Actually, no one here understood why she married him. She's very pretty. She could've had any man she wanted.
- Katharina: Who are you? Her new lover?
Jonas: I'm Jonas. Her son. Your grandson.
- Clausen: We have a man-eating cave. A nuclear power plant with a boss who is obviously hiding something. A detective who has gone into hiding. And a town full of people who lie, cheat, and betray one another, and who are all only concerned with concealing what's really going on here. So, Mr. Wöller, what do you make of it?
Torben: I don't know.
- Another timeline is added- 33 years earlier again- 1921, as Jonas travels back 132 years (33 x 4). There he meets his future great-great-grandmother, Agnes and her brother (the younger) Noah.
- Eastern Front - The Ostfront was the theater of operations in World War I in lands east of Germany, primarily pitting the forces of Germany and Austria-Hungary against those of Tsarist Russia and later the Soviet Union. Under both of the latter regimes, German and Austro-Hungarian POWs were subjected to forced labor and malnutrition, and living conditions generally bleaker than those on the Western Front, i.e. in France and the Low Countries.
- Fukushima - Aleksander alludes to the 2011 Fukushima Daiichi nuclear disaster as a reason for stricter security protocols at the plant. Why this would be the case is unclear, as Fukushima was triggered by a natural disaster, the Tohoku earthquake and tsunami of March 11, 2011, rather than a security breach..
- Clausen is the first person to ask Torben what happened to his eye.
- Waking – Jonas wakens with a start, this time in a grain field and in Erna's home.
- Martha has the same dream of having sex with Jonas and him telling her they are perfect for each other, and never to believe anything else, that Jonas had in "Beginnings and Endings." Does the fact that they both have the same dream mean this is not a fantasy but they actually did both have this experience?
- (Younger) Noah sits outside the cave eating an apple and talks to Jonas, just as the older Noah met Mikkel in Dark Matter.
- Noah's encounter with Jonas may be the episode he recounts to Helge in "Alpha and Omega": Years ago, I was still a little boy, a stranger came to us. He looked as if he'd been in the war. Didn't talk much. There was this sadness in his eyes, the kind you sometimes see in those who want to die, but life won't let them. He took a room in our house, the bedroom right next to mine. The 2020 Jonas may not be this stranger, however; Erna tells Agnes to prepare Noah's room for Jonas, not the room next to Noah's, and Jonas was not heard talking in his sleep.
- Aleksander tells Clausen that the door connecting the nuclear power plant to the Winden Caves was sealed shut in the 1980s. In fact, he was the one who welded it shut, as seen in "Everything is Now."
- Magnus and Martha leave Bartosz overnight in the caves just as their parents did 33 years ago.
- What is Agnes' (and Noah's) relation to Erna?
- What does Noah mean when he says he expected Jonas to look different?
- Why does the departing Jonas exchange looks with Agnes—but no words?
- How was the Sic Mundus lair built and furnished, and when?
- What is the "push" Adam alludes to in starting the next cycle?

The song played for the montage starting at 0:48 is "The World Retreats" by David O'Dowda, originally released in 2015 on *The World Retreats EP*.
The sign outside Winden's municipal library identifies it as the *Stadtbücherei Winden*, but the logo on Claudia's search results names it as the *Stadtbibliothek Winden*. Both are common terms for a public library, however, and it is possible one term refers to the institution and the other refers to the particular facility in town.
