So there's a couple of things that are bothering me:

1. The show claims that The Unknown is actually the child of Adam Jonas and Eva Martha. Who then go on to conceive Tronte with Agnes. Couldn't future Adam have just gone back and killed baby Agnes in 1888 to stop everything from happening. This in turn doesn't allow for Tronte to exist and start the family tree that leads to Jonas existence.
   
2. Soooooooo can we actually say that in theory, once again, Hannah is to blame for everything? She conceives Silja with Egon Tiedemann, who then creates Agnes and back to see above.
3. Who the fuck is Sebastian Kruger?! I see him in some timelines with relation to Hannah. Don't really recall seeing him in the show at all.
   
4. Claudia reveals that Tronte actually isn't Regina's father. So who is? In the timeline it shows Bernd Doppler as the father. Ummmm, how, what, when?! I assume this is true hence why she still exists in Origin World.
   

Despite these minute details that I'm probably missing something... LOVED the ending and the show as a whole!
