- This article is about the Katharina from Adam's World. For the Katharina from Eva's World, see Katharina Nielsen. For the Katharina from the Original World, see Katharina Albers.
Katharina lived with her abusive mother, Helene Albers, and her father Hermann Albers. Katharina was named after Hannah's new identity from 1953, where Helen met Hannah at an abortion clinic.
It is mentioned that she and Ulrich once tied Regina Tiedemann to a tree in the forest and left her there as a prank. Later, wrongly suspecting Regina has accused Ulrich of rape, Katharina attacks her in the forest, only driven off when a mysterious stranger, later revealed as Boris Niewald, appears brandishing a gun.
After Katharina travels back in time to 1987 through the gateway, she tries to look for Mikkel. It turns out that Mikkel has been sent away with Ines to get more rest after Ulrich tried to take him back to 2019. After Katharina learns that Ulrich is stuck in a psychiatric ward in 1987, she visits him to get him out of there.
In her attempt to free Ulrich, she has to confront her mother, Helene, who works at the ward and has a keycard, which Katharina wants to use to free Ulrich. Helene ends up killing Katharina in a fight for the keycard and drowns Katharina in the lake to hide her body, leaving only the necklace of Saint Christopher [needs citation]. Jonas to finds the necklace in this spot in june 2019. This means the legend of the drowned woman Bartosz tells about in 2019 is true, and is actually about Katharina.
Katharina is now principal of the school and mother of three. She remains a fierce woman to contend with, but the enemies she made in her youth have not forgiven her.
On June 20, Ulrich tries to pressure Katharina into having sex, but is interrupted by Mikkel, who enters their bedroom having developed a red rash all over his body, which his mother recognizes as rubella. As they head to the hospital, they find Jonas who has travelled from 1921 (via 2053) to this date and has a wound on his neck (which he covers up with his jacket). They are surprised he is not at the lake with the others and offer him a ride but he declines. Katharina, Ulrich and Mikkel make a stop at the Kahnwald's to pick up some extra glasses for their party.
Later, at the anniversary party, Katharina is in full party mode. She greets Hannah and Charlotte warmly and encourages them to dance and drink with the other guests. Upstairs, Mikkel wakes up feeling sick again, and after some pleading, has his mother come upstairs and lie down beside him in bed.
One day, Regina attacks her after a school performance, and Hannah carries on an affair with Ulrich.
She discovers Ulrich's many calls to Hannah and drives to the Kahnwald household to confront her, not knowing that Ulrich had earlier broken off the affair. The embittered Hannah lies and says Ulrich was planning to leave Katharina—something his disappearance seems to confirm.
Katharina is driven crazy by the fact that both her son and her husband are missing. In 2020, Katharina goes to the cave while looking for them.
June 24 Edit
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. She finds it impossible to believe that Ulrich and Mikkel have travelled back in time. Hannah tries to assure Katharina she travelled back and saw Mikkel. She tells them they have all lost their minds and leaves.
She goes to the school. She looks through old records of 1986 for Michael Kahnwald, who was a student then. She finds his class photo. She sees her son Mikkel in it and breaks down crying.
June 25 Edit
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.
She 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.
June 26 Edit
Katharina breaks into the Khanwald's house, searching for Hannah. On seeing Martha and Jonas together she pulls them apart and asks Martha whether she knows who this man is: The son of her brother, her nephew. She tells Jonas to keep his dirty hands off her and takes Martha away.
June 27 Edit
Katharina arrives with the device at the Kahnwald house seeking Jonas, but finds it empty. She looks around his room and finds his backpack, containing the orb light and his annotated Winden Cave map. She comes downstairs and spies a photo album of Michael. Leafing through it, she sees pictures of her son as he grew up, bringing her to tears. Jonas the adult 'stranger' walks in. She asks him how to use the machine and bring Mikkel back. Jonas tries to explain that it is impossible. Katharina says that he does not want him to come back as he won't exist. Mikkel belongs there, he doesn't. He replies that the past can't be changed, as he already exists and that the events that lead to his existence cannot be changed. He says he would trade his own life for Mikkel's, but can't because his future already exists. He thought he could prevent it but it is beyond his control.
Katharina goes to the caves with the map and orb light, and heads in. She follows the stream of time particles to the Sic Mundus door; as she opens it.
1987 (time travel) Edit
September 22 Edit
Katharina wakes up at the Kahnwald's home and looks at a picture of her with Mikkel. As she heads downstairs, the phone rings with the postal service threatening to disconnect her phone the following month if Ines didn't pay. Katharina picks up flyers which mentions Michael Kahnwald has been missing for three months. She puts it into a bag and leaves the house.
Katharina goes to the school and is handing out flyers, asking if people know Mikkel. All of a sudden, young Ulrich passes right in front of her; she says his name in surprise, which Ulrich hears and turns around. Ulrich asks if he knows her, and Katharina asks him if he knows where Mikkel could be. Ulrich says that maybe the lunatic (old Ulrich) had gotten him. When Katharina asks who he meant by the lunatic, Ulrich tells her to keep her hands off him. Young Hannah shows up greets Ulrich, as well as young Katharina, who thought that he was not going to school that day. Young Katharina kisses Ulrich, but is interrupted by Hannah who tells her they would be late for their history class.
Middle-aged Katharina remembers something, but mentions it out loud, which makes young Katharina ask what "her deal" was. Ulrich says she probably is crazy, and ignores her when Katharina asks about the lunatic again. Young Hannah turns around and tells her that somebody had escaped from the asylum last summer, grabbing "Michael" and taking him to the cave. Katharina grabs young Hannah suddenly and tells her to stay away from Mikkel and from Ulrich. Hannah is left in shock as she leaves.
Katharina walks inside the police station, demanding to know why she was not told about the man from the psych ward. The police officer she was talking to tells her tells her that she could not know any information on the whereabouts of Michael Kahnwald. Katharina tries telling him that Mikkel is her son, but the police officer tells her she has no proof, and refuses to identify herself. Katharina mentions that Mikkel had not been showing up to school, was not at home, and he had not been seen in three months.
Katharina was worried, but the police officer tells her that Child Protective Services knew where Mikkel and Ines were, so she did not need to worry. After the kidnapping, they decided the boy needed time off, and the lunatic returned to the ward where he had been for 34 years. Katharina asked for the name, but the police officer mentioned that if she showed up there again, she would be put under protective custody.
At the psych ward, middle aged Katharina walks in and asks if she can visit someone that had been there during 34 years. Since she was crying, the lady at the front desk asked if she knew her, because she looked familiar. She asked if she was related to him, and Katharina mentioned he was her husband. The secretary figured Katharina was one of the people who go for lunatics or prisoners because they are not able to find anyone else. She told her to return the following day until Katharina mentioned her necklace had Saint Christopher, the patron saint of travelers. She mentioned her mother also had one, and told the secretary that she had traveled a very long way to see him.
She was ultimately taken to see him, while old Ulrich played chess by himself. Katharina sat down in front of him, but he did not acknowledge his presence until she said his name. When he turned up to look at her, she gasped and he remembered her. Ulrich was overwhelmed, and started trembling. Katharina looked deeply at him, and swore she would get him out of there.
2019 (alternate version) Edit
November 4 Edit
Mikkel is playing a videogame, which Katharina tells him to turn off. Martha asks Katharina what's wrong with him, and Katharina tells her he had been having the same nightmares. Martha tells Mikkel that maybe it wasn't a dream, and that maybe the here and now was one, and none of them were real. Mikkel laughs sarcastically and the lights in the house start flickering, as Katharina takes his videogame away. Katharina asks if Magnus is awake yet, but nobody knows he is having sex with Franziska. Katharina offers them rides to school, but they decide to go on their own. She also reminds Martha that the next day they would be staying with their father. Martha is annoyed by this, but heads off for school.
At school, Katharina makes an announcement on the school's PA in which she summons all students to an assembly in the gymnasium. Hannah walks into the high school, and walks right into Katharina, who tries to ignore her. Hannah says she wanted to see her, and tells her she knows that she and the kids were a part of him and that she would back off. Katharina sarcastically thanks her, and tells her that Ulrich wanted to bring something over, when Hannah asks if Ulrich had been to her house earlier that morning
