OK, so I'm trying to sort out who now never existed. Obviously, Jonah, since Mikkel didn't time travel. Elisabeth didn't time travel, therefore no Charlotte the Police Chief. Therefore no Francesca and Elisabeth. And therefore no Noah/Hanno and Agnes. No Agnes, therefore no Tronte. No Tronte, therefore no Ulrich and Mads. (And there should be no Regina, but at the last minute they retconned out Tronte being her father.) No Ulrich, therefore no Magnus, Martha, and Mikkel. Regina seems single at the end, so did Aleksander get erased? Not sure why he would...but that would eliminate Bartosz, who otherwise would be the sole "survivor" of his generation.
