you were a child of Dottore, he found you at dusk when he was walking around the region when he saw you, he thought that you would become a new test subject, but when he realized that he was attached to you, he decided to become your father

today he had to go to a Fatui meeting, but he couldn’t leave you alone so he took you with him

"Dottore who is this child?" Scaramouche asked at the meeting

"This is my son/daughter." Dottore said
