Claire Novak (Kathryn Love Newton)
After Castiel took Claire’s father, Jimmy, as his human vessel, her mother left and the runaway teen became a thief. The budding hunter and bundle of teen angst now lives with Sheriff Mills and helped save her foster sister, Alex Jones, from vengeful vampires. “Claire adds a nice twist to Castiel as he tries to be a father figure,” Ackles says. “Kathryn is a fan, cast and crew favorite.”
