Eden (surname unknown) is a girl who was in an abusive adoption agency. She developed a close bond with Detective Dani Beck, which led Beck to foster her until an arrangement could be made.
However, the traumatized and mentally disturbed Eden set Beck's house on fire in an attempt to try and kill the both of them so that they could be together forever. Traumatized, Beck decided to stop fostering Eden, later opting to leave the Special Victims Unit and return to her old assignment in the Warrants Squad. It is unknown what happened to Eden afterwards. (SVU: "Cage")
