Supernatural Season 8 Episode 15 Man's Best Friend with Benefits

Dean and Sam Winchester investigate a case involving a man who has apparently been killed by his own dog. As they start to look into the circumstances surrounding the man's death, they soon realize that the dog is not just any ordinary pet - it is a hellhound. The brothers learn that the man had made a deal with a demon, and the demon had given him the hellhound as a reward.

The Winchesters' investigation is complicated by the fact that the hellhound has now turned on its previous owner and is now seemingly out of control. As they try to track down the demon responsible, they encounter a woman named Portia who claims to have control over hellhounds and offers to help them with their investigation.

As the brothers work with Portia, they start to unravel the complex network of deception and betrayal surrounding the case. They also quickly discover that Portia has her own hidden agenda and is not entirely trustworthy.

Meanwhile, as Sam and Dean investigate the case, they begin to confront their own personal demons. Dean struggles with his guilt over his role in causing Castiel's death, while Sam is haunted by the fact that he may have inadvertently caused Kevin's death.

As the Winchesters try to come to terms with their own emotional baggage, they must also deal with the ongoing threat posed by the demon and its hellhound. With time running out, the brothers must use all of their ingenuity and resources to defeat the demon and save the innocent people caught up in its machinations.

In the end, the Winchesters emerge victorious, but not without paying a steep price. As they continue on their never-ending quest to rid the world of evil, they are reminded once again of the high stakes and terrible consequences of their chosen profession.
