Jonas Kahnwald is the son of Michael and Hannah Kahnwald. Following his father's suicide, Jonas was left traumatized. After Mikkel Nielsen's disappearance, Jonas found a map in his father's art studio and received a package from a stranger, leading him to discover a wormhole that brings him into the past and later, the future.
Family background Edit
Jonas is the son of Hannah and Michael Kahnwald. Michael Kahnwald was originally Mikkel Nielsen, who travelled through time from 2019 to 1986 and grew up with adoptive mother Ines Kahnwald, keeping his real identity a secret. Thus, Jonas' biological paternal family are the Nielsens: Ulrich and Katharina are his grandparents and Martha and Magnus are his aunt and uncle.
Jonas left Winden for several weeks of therapy following his father's suicide. Upon returning, he was haunted by nightmares and visions and found that his love interest Martha Nielsen was dating his best friend Bartosz.
The trio went to the Winden Cave with Magnus and Mikkel Nielsen, hoping to find missing kid Erik Obendorf's drug stash. Strange phenomena occurred and Mikkel Nielsen vanished.
Jonas was followed by a mysterious stranger, who was his adult self from the future, come back to change the course of time. He gave Jonas a parcel with a futuristic lamp, a geiger counter and an aged version of his father's suicide note, and added notes to a map Jonas found in the attic.
Guided by this, Jonas entered the cave, went through a metal trapdoor and emerged from the cave in 1986. He found the missing Mikkel at the hospital but followed his future self's advice not to bring him to the present as it would eliminate his own existence, because Mikkel would grow up to become Michael Kahnwald – Jonas' father.
Jonas was distraught to understand how everyone is connected – his crush Martha was his aunt and his mother's lover Ulrich was his grandfather – and burnt his father's letter. He rejected Martha, so she told Bartosz of their kiss, which ruined their friendship.
Talking to his grandmother Ines, Jonas discovered that she always knew of Michael's true identity, and she gave Jonas his suicide note, which Jonas had already burnt.
“Now I have another grandma and she's the principal of my school! Her husband who's fucking my mom, is looking for his son who is my father! A few days ago I kissed my aunt.” ― Jonas KahnwaldSetting out to change time, Jonas travelled to 1986 and went to the hospital to find Mikkel. He was captured by Noah and Helge and locked in the child's room in the bunker. Jonas' future self visited him again, but did not set him free as he would not become the man that his future self now is.
When his future self tried to destroy the wormhole in the cave, a time portal opened, connecting Jonas to 1953. He touched hands with Helge Doppler, and was transported to the year 2052. In the same place, there was a stone wall with photographs of the residents of Winden. As he left the bunker, people in military clothing were waiting for him and he was knocked unconscious by Silja.
As young Jonas (2020) travels back in time to 2019 the day of his fathers suicide, which is believed to be what started it all, after being convinced by his older self Adam, he talks to his father Michael. He gets very emotional seeing him after such a long time, and he tells him that he knows what he will later do the same day. Michael repeatedly tells Jonas that he is the one who started it all,because he was the one to lead young Michael (Mikkel 2019) to the cave in the forest at the night of his dissappearace and his older selves suicide. He tells him that they were in the forest together when the cave when the sounds started, but then Jonas suddenly disappeared in the woods. Jonas then later came back and told young Michael to go with him into the cave since the forest was dangerous. Michael was scared, but he went with Jonas because he trusted him and had nobody else at the time. Jonas is shocked by that, because he couldn't remember doing or saying such a thing. He just went back into the town with his other friends, where the parents were scared
As an adult, Jonas has gained more knowledge about time travel and the happenings in Winden. Arriving from another time to 2019, he moves into the Waldhotel in Winden. He is on a mission to destroy the time loop by collapsing the wormhole in the cave by using the apparatus.To ensure that he will not endanger his own existence, Jonas steers his younger self on a predetermined path, giving him his father's suicide note and leaving marks on his map which leads him to the cave to the past. Jonas stops his younger self from bringing Mikkel back from 1986 to 2019 and does not release his younger self from the bunker where he is imprisoned by Helge and Noah. Thus, he ensures that his younger self will reach the future through a time portal which opens when he collapses the wormhole.
Jonas has an introverted, quiet personality type, with a form of PTSD due to the death of his father. He is curious about the concept of time travel seen in his future self (the stranger) and realised that he must destroy wormholes in order for everything to go back to normal. In the future he is much the same but more jaded and cynical unaware he is creating the wormhole.
Mental Health Edit
Jonas has hallucinations and dreams of his father Michael/Mikkel which are a manifestation of his PTSD during high anxiety for which he is taking medication, Amitriptyline, prescribed by Peter Doppler. Examples of this are the following. In E1 Secrets, Jonas hears someone call his name and sees Michael covered in black substance just after Mikkel goes missing in the forest near the cave. In S1:E2 Lies the next morning Jonas dreams of black substance oozing from his ear and when he looks in the mirror sees Michael covered in black substance again just prior to waking up. In Dark Season 1 Episode 10: "Alpha and Omega" Jonas dreams he is awoken by a hand on his shoulder and when he turns over in bed he sees Mikkel lying next to him, after he really wakes up he throws away his medication. Finally in Dark Season 1 Episode 10: "Alpha and Omega", after Jonas/The Stranger activates the apparatus in the cave and sits down he turns to see Michael also sitting near him covered ina black substance. The black substance could be oil- based black paint since Michael was a painter and several of his paintings were exclusively in black.
Jonas as an adult guides Jonas' actions in his youth. As an adult, he appears to be allied with Claudia.
