After being sprung from Sioux Falls General by a perfectly alive Bobby, Dean and Sam join him and lay low for three weeks while Dean's broken leg heals. In that time, Sam has still suffered hallucinations, but has kept them quiet. While collecting food, Sam discovers the return of an unknown serial killer and takes off on his own to find her. In truth, the killer is a Kitsune, a monster who removes the pituitary gland in the brain as nourishment. Sam eventually tracks down the monster as an old acquaintance, Amy, who years ago he had a crush on while hunting Amy's mother. When Sam confronts Amy on the deaths, she reveals that she has a son who she cares for, and who needed fresh meat in order to survive an illness brought on by harvesting dead bodies. As Amy had helped protect and defend Sam, even killing her own mother, Sam lets her go. Dean manages to catch up to Sam and get the truth to his disappearance, and urges Sam to find Amy and kill her. Sam refuses, and acknowledges Dean has been treating him like a hand grenade, and emphasizing that he is managing his hallucinations and atoning for his past actions. Dean agrees to stop badgering him, but later tracks and kills Amy in front of her son, stating that no matter what changes a person goes through, they are still the same person. Throughout, the Leviathan are shown to maintain an eye on the various rocker aliases of the brothers, using the aliases to catch up to them.
