June 21, 2053[]

The young Jonas Kahnwald, at the derelict nuclear power plant, listens to Claudia Tiedemann's tape about the God particle. She says that if it is stabilized it might permit time travel. A generator needs to supply sufficient AC current, It seems to contradict the second law of thermodynamics. He looks at diagrams and pulls a switch. The God particle stabilizes into a smooth sphere. But then the power shuts down and it resumes its unstable previous state. A frustrated Jonas realizes the generators have run out of diesel.

5 days until the apocalypse (June 22, 1987)[]

In his new life in 1987, Mikkel Nielsen awakes with a start, panting. He goes downstairs to where Ines Kahnwald (now his adoptive mother) prepares his lunch. She tells him everything will be better soon as there is only one week of school left before vacation. Mikkel tells her it is his mother's birthday. She reminds him that the past is past and now is now.

Egon Tiedemann visits his daughter Claudia. She says she is too busy to do anything with him, as she must meet with a French delegation. Gretchen the dog comes in and Egon remarks about the similarity to their long-gone house pet, which Claudia dismisses. He tells her there is something he needs to talk to her about but sensing she is too busy, then says it's nothing and leaves.

June 22, 2020[]

At the police station, Charlotte Doppler examines the photo with Noah that her daughter Elisabeth found the day before. She does a web search on "Sic Mundus Creatus Est" and finds it translates as "Thus the world was created".

She asks Clausen why they are starting their interviews with Regina Tiedemann. Clausen suspects a connection between the power plant, the caves, and the fact that Aleksander Tiedemann took his wife's name when they married.

At the Doppler home, Magnus Nielsen accuses Franziska Doppler of prostituting herself for money, having seen her exchange envelopes with Benni. She informs him that she is providing hormones to Benni for her sex change, which she has taken over from her father. She is furious with Magnus for spying on her, making assumptions, and judging her.

Hannah Kahnwald looks through old family photos—happier times. The older Jonas enters and shows her his time machine that can travel thirty-three years into the past or future. He tells her he wants her to see for herself the truth about her husband.

June 22, 1987[]

Mikkel hesitantly walks to school. He is shoved by a passing Katharina Albers, his own mother, while the younger Hannah looks on. Instead of entering the school, he turns around and heads for the caves, where Noah waits. Noah discourages him from going into the cave, saying that some have gotten lost and never come out. Mikkel questions what Noah said the year before about God and His having a plan for everyone, wondering what if God is wrong. Noah feigns offense, saying that God never errs. He says sometimes we just need to have faith that things will get better.

At the nuclear power plant, Claudia is informed that a woman has come to claim the dog. The old woman picks the dog up, calling it Gretchen—telling her the dog is hers, just as it is Claudia's. She tells her to look through the window and proceeds to tell her everything that will happen. She tells her she is her and was in her exact position thirty-three years ago. When Gretchen ran into the cave in 1953, she was there waiting for her and made sure she would find her.

Egon receives a call telling him his cancer has spread, and he will need to start treatment that week. He sees a newspaper headline pointing out that the disappearance of Mads Nielsen one year ago was never solved. Pulling out his old notebook, he sees his note asking why Helge Doppler did not take the forest road home.

June 22, 2053[]

Jonas walks to an upper floor of a derelict apartment building and wires an old CD player to speakers and blasts Elvis singing "Suspicious Minds" from the window, hoping to create a diversion. A team of soldiers arrives in a tank. All get out to look for the perpetrator, enabling Jonas to siphon diesel from the tank, narrowly avoiding detection.

June 22, 1987[]

Regina meets Aleksander in the forest. She tells him her mother is never there and only complains about her. She has never told her she loves her. Aleksander offers to make up for that and kisses her.

June 22, 2020[]

At the Tiedemann home, Clausen asks Regina why Ulrich Nielsen visited the hotel the day he disappeared. She tells him he asked about Mads's disappearance, she being the last one to see him alive. He then asks why her husband took her last name. She asks what that has to do with this. She tells him about the stranger who asked for a room, but never returned, leaving behind many papers on the wall which she shows him, also asking her to deliver a package to Jonas.

Hannah and Jonas go into the caves. He activates the machine, using Ulrich's smartphone. He takes her back to 1987.

June 22, 1987[]

Egon decides to pay Helge a visit, who is making his stick figures in a hospital, recovering from his car accident. He asks him why he took the long way home instead of Forest Road? Helge replies cryptically that the man with the stone (Ulrich) had told him he could change the future and the past, but no one, not even the "White Devil" could change anything. Egon asks him what that has to do with Mads.

The older Claudia takes her to the cave where the barrels are stored and shows her a time machine that is bigger than any of us, that can travel thirty-three years backwards or forwards. It takes thirty-three years for the cycle to complete, and it will do so again in five days. She tells her she must stop Adam. She warns her that life is a collection of missed opportunities. She does not have much time left with Regina, but if everything works out she will live. She activates the machine and disappears, leaving Claudia shocked.

June 22, 2053[]

Jonas takes the diesel into the restricted area but is met by three soldiers with guns pointed at him.

June 22, 2020[]

Charlotte looks through the papers and recognizes some from her grandfather's book. She relates this to Peter. She asks him why her grandfather never told her who her parents were.

June 22, 2053[]

Jonas is placed on gallows, with a noose around his neck. The teenaged girl, interpreting for Elisabeth, reminds him of the consequences of entering the restricted area. Jonas defiantly asks Elisabeth why she is lying about what is in the restricted zone, to which Elisabeth shoots him in the leg. He shouts that in five days everyone is going to die and he has to stop that. The passage will never open and the prophecy is false. Elisabeth kicks the board out from under him. Elisabeth watches him as he chokes, then decides to shoot the rope holding him from the gallows and he falls to the ground.

June 22, 1987[]

Egon calls the police station and asks whatever happened to the man arrested in 1953 for the attempted murder of Helge and two boys. He is informed that he is in a mental institution, where he has been for thirty-four years.

Egon goes to visit him. Ulrich is known as "the Inspector". Egon introduces himself, unsure whether he would remember him. Ulrich assures him he remembers him and quotes him the same lines he had said previously: "My only aim is to take many lives, the more the better I feel." Egon asks what it means. Ulrich tells him they mean he is still an idiot. He tells him he doesn't have much time until he is dead, which was in the papers, which Egon cannot follow. Ulrich tells him his fate is to always be clueless. He will get what he deserves.

Later that night Mikkel returns home, where Ines has been worried about him. She tells him she will make him Toast Hawaii to cheer him up. It was her childhood comfort food, with cherries on top, and her father would dance like Elvis. He asks her whether she believes in God and if he has a plan. She says she does and that God planned for her to take care of him. He then goes to her and hugs her.

The older Jonas and Hannah arrive at the Kahnwald home. They see Mikkel with Ines as they have dinner together. Hannah cries as she realizes her husband's past.

June 22, 2053[]

Jonas is placed in a cage, wounded in his leg and neck. Elisabeth's interpreter visits him and demands to know who he is and why Elisabeth didn't kill him. She releases him and asks him to show her what's in the dead zone. He takes her to the power plant where the God particle vibrates. Jonas pours the diesel he stole into the generator and starts it up. The God particle stabilizes into a smooth sphere again. He tells her that according to Claudia, that could be the way to get home. He goes inside, telling her it doesn't matter whether he dies here or in there. The particle erupts again. Jonas vanishes.

June 22, 1987/1954[]

Claudia later goes home and digs a hole in her backyard. She finds the portable time machine at the exact spot that was marked on her older self's map. "Meanwhile" that same night thirty-three years before, the older Claudia buries the time machine before the Tiedemanns' '80s house had even been built.



"We have managed to stabilize the God Particle and the resulting mass. In a stable state, it seems to create a kind of portal which possibly allows for time travel. If the matter is supplied with sufficient voltage, it can be kept in a stable state in the long term. Sending objects through the stabilized matter has already proved possible.... A generator has to provide sufficient AC current for that. Even after lengthy observation, we are not sure what the energy source of the instable matter is. Measurements indicate there is no form of energy loss. It appears to be a type of self-sustaining recursive system.... The matter’s radiation levels exceed control values. Still, no signs of decay have been observed. This is consistent with the law of conservation of energy, yet it contradict the second law of thermodynamics. Moreover, the matter seems to exist, independent of external temperature, in solid, liquid and gaseous states at once. And the molecules seem to be in a constant cycle...."
―Claudia, on a tape recording, describes the nature of the God Particle
"Sometimes we don't really know where we're supposed to be. But I wouldn't go in there. It's like a maze in there. Some have never returned."
Noah to Mikkel outside the caves
"In the hospital, you said something... the thing about God, and that He has a plan for everyone. What if God has no idea what He's doing? If the plan is wrong? If God is mistaken?"
"God doesn't make mistakes. Sometimes we have to have more faith that everything will be okay again."
―Mikkel questions Noah on God
"Why didn't you take the forest road?"
"He... He said he can change everything. He can change the past, and the future."
"Who said that?"
"The man with the stone."
"But that was thirty years ago. What does that have to do with Mads?"
"But no one can change it. No one. Not even the White Devil."
"The White Devil? You've said that before. Back then, as a child."
"Tick, tock.... Tick, tock.... Tick, tock...."
Egon questions Helge at the rest home
"'My only aim is to take many lives. The more, the better I feel.'"
"I know that. You've said that before. What does it mean?"
"It means that you, you moron, still haven't understood a thing. But now you have to hurry. You don't have much time left. I know when you die. It was in the paper."
"I don't understand."
"No, of course you don't. But maybe that is also your fate. To die as clueless as you were born. Everyone gets what they deserve."
―The elderly Ulrich taunts Egon
"There are days it's best to just forget."
Ines to Mikkel
"What is that?"
"She said that it's a portal."
"I have tapes with a woman speaking on them. Her name is Claudia Tiedemann. I know none of this makes sense, but that may be the only way back home. No clue if it works."
"You want to go in?"<br"It doesn't matter if I die out inside it or out here."
Jonas to the girl from the future about the God Particle



  • Who is the White Devil?
  • What does the older Claudia mean by "if everything works out, then Regina will live"? She states that her middle-aged self does not have much more time with Regina.
  • Reinforced this episode after being hinted at last episode, who are Charlotte's parents?
  • When will Egon die?
  • Where does the dark matter take Jonas?


  • Franziska has been selling hormone treatment to Benni, contrary to Magnus's worst assumptions.
  • Claudia became involved in time travel after being visited by her older self.
  • Egon has cancer.
  • The older Claudia was the one who brought Gretchen from 1953 to 1986 for her middle-aged self to find in "Everything Is Now".
  • Regina kept all of the Stranger's belongings that he left in his hotel room in November. She never brought them to the police.
  • We see how the portable time machine works for the first time.
  • Jonas received the scar around his neck from a hanging in 2053 at the hands of Elisabeth.
  • Ulrich is still alive in 1987: He has been living in a psychiatric ward for the last thirty-four years and is now an elderly man. He is known around the place as "the Inspector" but has still never revealed his name.
  • The girl from the future also has a light orb like the one Jonas got from his older self. This shows these devices are somehow products of the future.

Themes and Motifs[]


  • The dates featured in this episode are: June 22, 1954 (briefly); June 22, 1987; June 22, 2020; and June 22, 2053.
  • This episode continues the countdown to the apocalypse. It is now 5 days until the apocalypse.
  • Egon looks at his Police Calendar from 1986.
  • Egon references the time when Helge was a boy and spoke of a "White Devil", presumably the 1950s.
  • Jonas tries to convince Elisabeth's cult that there is no paradise and that in five days, everyone in his time will die.


  • Mikkel awakes in the same bedroom and the same manner as his future son 33 years later, both having experienced traumatic events and the loss of parents. Ines calls him Mikkel so he must have finally told her his real name, though he became Michael.
  • Presumably, by the way he looks at her, Mikkel knows teenage Katharina is his mother, though she has no idea and shoves him, which seems to upset him.

  • Ulrich remembers reading about Egon's death when he was a teenager in 1987.
  • The neck scar from the almost hanging remains with Jonas for the rest of his life and can be seen in the "Stranger"/ older Jonas.
  • Why does Elisabeth save Jonas? Does she remember him from when she was a girl in 2019?
  • Jonas is determined to do all he can to prevent the apocalypse, even if it leads to his death.
