Isolde is the emotionally distant and cold mother to Helmi. She's complicated individual. She's worked hard to be where she's at, a woman who is the head of the science branch of their government and the forefront to a lot of war time bio-weapons. She's more or less happily married, or at least in a good partnership with her second husband Henry. She gets on Helmi's case a lot since both are very similar in how they rationally view the world, but Helmi has a heart while Isolde's has a prison security center around it.

She's manipulative and normally gets her way. She will respect those who stand up to her and wait for the "I told you so" moments when they will come.

Fun facts: she's in her 60s, silver white hair, always dresses classy, will always follow curiosity "for the sake of science", and deep down she wants to be a better mother and person, it's just hard for her to do so.
