Season 1: Daughter of Peter and Charlotte Doppler, we see 2019 Elisabeth (Carlotta von Falkenhayn)just being a rebellious pre-teen — chasing boys, stealing her sister Franziska's lipstick, and wandering off alone, where she's the first one to meet Noah and return unscathed.
Season 2: A fairly unimportant character in the first season, Elisabeth is revealed to be a much more integral (and complex) character in season 2. Not only do we follow a 2019 Elisabeth, but now we see her in 2053 (played by Sandra Borgmann), dirty and scarred and in command of a post-apocalyptic Winden. To complicate matters further, it's revealed (not to Elisabeth herself) that she is both Charlotte's daughter and mother (meaning they're each other's grandmothers) and wife to a past Noah and whoa! things just got exponentially weirder.
Season 3:
- Adam's World: In 2020, Elisabeth and her father, Peter, are both living in post-apocalyptic Winden. Elisabeth meets young Noah, who she eventually helps dig out the cave tunnels with. The pair go on to have a baby, Charlotte, who is taken from them in 2041 by 2019 Charlotte and 2053 Elisabeth. This duo brings baby Charlotte to H.G. Tannhaus in the 1970s, who then raises her as his own grandchild.
- Eva's World: In Eva's world, Elisabeth isn't the Doppler sibling that's deaf, but that's basically the only change with her character up to the year 2020. Right before the apocalypse, older Noah, sent by Eva, appears to take her to the bunker (where his younger self is), in order to ensure that she's saved and that Charlotte can later be born.
- Origin World: Elisabeth doesn't exist in the origin world, as her entire life is a loop of being born of and giving birth to her mother, Charlotte, due to time travel.
