Clausen and Charlotte interview Regina. The Stranger takes Hannah to 1987, where Claudia has an unnerving encounter and Egon visits an old nemesis.
Jonas, at the derelict nuclear power plant, listens to Claudia'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.
He 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.
He takes the diesel into the restricted area but is met by 3 soldiers with guns pointed at him.
He is placed on gallows, with a noose around his neck. Silja, 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 5 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.
On June 22, Mikkel awakes with a start, panting. He goes downstairs where Ines (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. He tells her it is his mother's birthday. She reminds him that the past is past and now is now.
Egon visits 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, 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.
She asks Clausen why they are starting their interviews with Regina. Clausen suspects a connection between the power plant, the caves, and the fact that Aleksander took his wife's name when they married.
Clausen asks Regina why Ulrich visited the hotel the day he disappeared. She tells him he asked about Mads' 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.
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.
At the Doppler home, Magnus accuses Franziska 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 looks through old family photos- happier times. The older Jonas enters and shows her his time machine that can travel 33 years into the past or future. He tells her he wants her to see for herself the truth about her husband. They go into the caves. He activates the machine, using Ulrich's smartphone.
He takes her to her home in 1987 where they see Mikkel with Ines as they have dinner together. Hannah cries as she realizes her husband's past.
Mikkel hesitantly walks to the school. He is shoved by the teenage Katharina, while the younger Hannah looks on. Instead of entering the school, he turns around and heads for the caves, where Noah waits. Noah warns him not to go into the cave, as some never return. Mikkel recognizes him from the hospital and asks him about God's plan that he spoke about, whether it was possible that God's plan could be wrong? Noah curtly replies that God is never wrong, we need to keep the faith that things will get better again.
Later that night he returns home, where Ines has 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.
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 position 33 years ago. When Gretchen ran into the cave in 1953 she was there waiting for her and made sure she would find her.
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 33 years backwards or forwards. It takes 33 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.
Claudia later goes home and digs a hole in her back yard, and finds a time machine that was buried by her older self in 1953 before the house had even been built.
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 did not take the forest road home.
He 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 the 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?
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 34 years.
Egon goes to visit him. He 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 they mean. 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.
Jonas is placed in a cage, wounded in his leg and neck. Silja 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.
- Claudia: “We have managed to successfully stabilize the God Particle, and consequently the resulting mass as well. 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. Despite lengthy observation, we have yet to determine the matter’s energy source. It would appear to be running entirely on its own. The readings indicate that there is no loss of energy. 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. While this is consistent with conservation of energy, it does contradict the second law of thermodynamics. The matter seems to exist, independent of external temperatures, in solid, liquid and gaseous states simultaneously. Its molecules are continually rearranged in a cyclical process. The presence of the field explains why…”
- Noah: Sometimes we don't really know where we should be. I wouldn't be going in there—it's like a maze in there; some don't come back out.
- Mikkel: At the hospital, something you said... about God and how He has a plan for everyone. What if God doesn't know what He's doing? If the plan is wrong? If God is wrong?
Noah: God is never wrong. Sometimes we need faith that things will get better for us again.
- Egon: Tell me why you wouldn't take the forest road?
Helge: He said he could change it—that he could change everything, the future and past.
Egon: Who told you that?
Helge: The man with the stone, but that was 30 years ago.
Egon: What's this to do with Mads at all?
Helge: Nobody can change it. Nobody! Not even the white devil!
- Ulrich: "My only aim is to take many lives. The more, the better I feel."
Egon: I've heard that. You've said those words before. What the hell does it mean?
Ulrich: It means you're still an idiot who doesn't understand. You have to hurry now. You don't have much time until you're dead and buried. It was in the papers.
Egon: I'm not following you.
Ulrich: No, of course you aren't. Maybe that's your fate: to die as clueless as you were born, you know? Everybody gets what they deserve.
- Ines: There are some days you just have to forget about.
- Silja: What is that?
Jonas: She said that it's a portal.
Jonas: Tapes of a woman talking. Her name is Claudia Tiedemann. I know it sounds crazy, but that could very well be our way to get home. I don't know if it works.
Silja: You're going in?
Jonas: Whether I die out here or in there doesn't matter.
- 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.
- Noah assures Mikkel that God exists and has a plan. He previously told Helge there was no God.
- Aleksander (who we know is someone else) took his wife's name when they married
- Claudia meets her older self, similar to Jonas
- The older Claudia was responsible for Gretchen disappearing in 1953 and returning unchanged in 1986.
- Ulrich remembers reading about Egon's death when he was a teenager in 1987.
- The neck scar from the almost hanging remain 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.
