Selwyn worked as a successful fashion model until meeting Selwyn, who she later married and had a daughter with. She was described as a homebody who rarely traveled to Los Angeles and out of her family's servants, she had a preference for Arkady.
In November 2019, Isobel, Cleo, Arkady, and Isobel's spinner disappeared after attending Lydia Tyrell's birthday party. Days later, she and Isobel traveled to meet Malak. Upon arriving at the meeting spot, he was not there and the mother and child were attacked by two men and a woman. Isobel managed to incapacitate them before Malak finally arrived.
Malak led them to an underground community and introduced them to "the Lung." After Isobel and her daughter donned disguises, the Lung prepared them for a venture out of the city, during which they would be escorted by "the Bones."
