you and your adopted brother/sister have known Spencer since childhood. you went to school together and then to the FBI Academy. the three of you were inseparable, but after graduating from the academy, you didn't see each other for ten years, because Reid was the only one who went to work for the FBI right after graduating from the academy

now, after ten years of separation, you and your brother/sister were hired in the BAU at Quantico, where the team members are already looking for information on the two of you
