WARNING: The following article contains major spoilers for the third and final season of Netflix's Dark, streaming now.

As the third season of Dark ramped up, the Netflix hit series throws fans for a major loop when young Jonas is killed on Earth-2 after making a series of time-jumps. He was brought there at the end of last season by Martha 2.0 after his Martha was killed by Adam (Jonas' disfigured older self), with promises if he helped stop her apocalypse, she'd help him stop his and break Winden's time-knot inexplicably linking both worlds.

However, in a shocking moment, this teenage Jonas is revealed to be alive and well thanks to a "glitch in the matrix," or as viewers soon discover, quantum entanglement.

Adam's been manipulating the apocalypse on Earth-1 while Eva (a darker and older Martha) is doing the same on Earth-2. However, while Adam wants to break the knot and destroy both worlds, Eva facilitates both disasters knowing that it's how their worlds are created and reborn. Unlike Adam, she wants to keep this cycle of life and death going as it allows her and Jonas' son to live. Ultimately, Martha 2.0 and Jonas stand up against Eva, realizing she's been using them as pawns all along. They thought she was helping stop the nuclear meltdown on Earth-2 but as her middle-aged self comes from 2053, it's clear Eva is demented.

Jonas is sick and tired of being played as Adam did the same to him on Earth-1, but suddenly, another Martha 2.0 arrives. She has a scar, however, across her face and she kills Jonas, mimicking the scene when Jonas mourned Martha 1.0. But in the future, when Claudia is doing experiments with the God Particle as she becomes the White Wolf, young Jonas is there. It's all due to a loophole where the apocalypse on Earth-1 creates parallel realities due to quantum entanglement. The loop sends life one way, which has led to Jonas' shooting, but it can go the other way where Martha 2.0 doesn't save Jonas from Earth-1 and all this never happens. Instead, Bartosz from Earth-2 is told by his dark, older self (an acolyte of Martha) there to stop Martha 2.0 from saving Jonas in the Season 2 finale. She's then taken to Eva, who scars her and manipulates her to go shoot Jonas in the meeting.

People can exist in the same time/space according to the time laws, and this scarred Martha 2.0 is trying to save her unborn kid, telling the original Martha 2.0 she won't understand just yet. But because the other Jonas hides out at home and survives Earth-1's apocalypse, he goes on to work with Claudia and thus, becomes the middle-aged Stranger. He'd then go back in time as per Season 1 as they plot a plan, not knowing the White Wolf has been educating her younger self and making them her pawns, but for the greater good. This would lead to the Stranger, per Season 2, taking the Travelers to 1888 where he becomes a burnt up Adam from his experiments. He's bitter Martha 2.0 just came and left nuclear material behind.

The knot remains intact because this Stranger never went to Earth-2 so that's why he doesn't have those memories of Martha 2.0 and Eva. The dead Jonas had all those memories and he was simply used to kickstart the apocalypse on Earth-2 while Jonas/Stranger/Adam does the same on Earth-1. As for this quantum entanglement, Claudia ensured all dominoes stemming from Jonas' dad's suicide in Season 1 would lead to this. She needed everything on both Earths to happen as is, as she has finally discovered the breaking point of the knot: an original Earth these two worlds were split off from. In other words, she needed that fracture of reality to get two Jonases so she could manipulate things on both Earths.

Created by Baran bo Odar and Jantje Friese, Dark stars Oliver Masucci, Karoline Eichhorn and Jördis Triebel. Season 3 is currently available on Netflix.
