Season 1: It might come as a bit of a shock that 1986 Regina (Lydia Maria Makrides) — a kindhearted, curly-headed nerd — grows up to be the glamorous-but-stressed-out Regina of 2019 (Deborah Kaufmann). As the series goes on, you begin to see what causes Regina's transformation and why she carries such a chip on her well-dressed shoulders.
Season 2: Suffering from breast cancer, 2019 Regina spends most of the second season getting treatment at home. That is, until her mother Claudia time travels from 1986 to see her and try to rescue her from the impending apocalypse and brings her to the bunker. At season's end we leave Regina in the bunker with Peter and Elisabeth Doppler.
- Adam's World: After being taken to the future by her middle-age mother, Regina's health declines. The pair are staying in the abandoned police station, where an old Tronte Nielsen comes on old Claudia's orders to kill Regina.
- Eva's World: In this reality, Regina dies in September 2019, so we don't see her alive.
- Origin World: In the origin world Regina is seen in 2019, still friends with Hannah and Katharina. Aleksander doesn't appear to be in the picture, as without Ulrich, Katharina likely never bullies Regina in the woods on the day she met Aleksander in Adam's world (if he's even there in the origin world in the first place!).
