Kristina is the oldest child of Karl and Marianne Lister. She grew up in a happy, calm home with her parents, siblings and cousin Ben.
Her mother, Marianne, died in a car accident in 2012. Karl didn’t deal well with this, so Thomas took over Ben’s care. In 2013, Karl decided to end his life by hanging himself in his garage. Kristina found him, which she still struggles with to this day.
