Hanno was re-named Noah by Adam but his reasons for doing so remained a mystery.
Going by the biblical theme, Noah later likened his crude time machine to an ark as he sought to save humanity.
He believed Adam was on the side of good and followed him blindly without realising they were all locked in an infinite cycle.
Unfortunately, he was left disillusioned and tried to take revenge on Adam after learning his daughter was Charlotte Doppler (Karoline Eichhorn) – the mother of his wife Elisabeth (Sandra Borgmann).
Ultimately, Noah/Hanno was simply a pawn in the cycle and died hoping he could change the future.
