Sam

Sam is a police officer that Meg robbed when she was younger. Based on flashbacks, it is implied that Sam once had a family (a wife and daughter), that are now dead as he carries around his daughter's doll with him. He saves Charlie and Shirley from falling debris at the area Jo was fighting Lava, one of the "Genocide Angel" candidates. Afterward, he adopts all three children while Meg and Jo leave their own way.
