My theory *SPOILERS* Tronte is
Noah's son. And Noah is in fact... Bartosz!
Anyway, bloody good series! I can't remember being so excited about a series and possible 2nd season before!
That's what implied.. But hear me out.
Noah is the only person whose versions are not shown as per the year we are in. I.e. 53/86/2019/2052.
So, if Noah = Bartosz, then what we seem him is his version from 1952. He screws the the lesbian lady when he travel back in time and Tronte is born. That means he travels back to 1953-12 = 1941 or so. Isn't it? Would that be possible.
I was thinking about it last night in bed, and something doesn't add up
