When Supernatural first started, it was about two estranged brothers, Sam (Jared Padalecki) and Dean (Jensen Ackles) Winchester. Sam was going to college and trying to forget about the death of their mother, while Dean was busy following their father and trying to hunt down the demon that killed her. But everything changed when their father went missing and the demon that killed Mrs. Winchester killed Sam’s girlfriend. Vowing to track down the demon and find their father, the two set off for an adventure that would bring them face to face with monsters, demons, and creatures of ancient lore.
While the first two seasons served up storylines more along the monster-of-the-week mindset, seasons three and four made a more dramatic turn bringing the Winchester back-story to the forefront. Dean had a year to live as he traded his soul in order to save his brother’s life. Most of season three covered their attempts to find the demon that owned the contract to his soul and how they might find a way out of the deal. In the season finale, they failed to find an answer and Dean was dragged to hell by the demon Lilith.
Season four starts off four months later. Dean has been in Hell for what has seemed to him like forty years, and suddenly finds himself back on Earth. He remembers every moment of the torment that he suffered, but has no memory of how he managed to escape. Having a hard time dealing with the loss of his brother, Sam turns to the demon Ruby (Genevieve Cortese), who Sam believes is trying to help them. Not only does he become romantically entangled with her, but he is consuming her blood to give himself powers. While Dean is occupied on finding out how and why he escaped from Hell, Sam is finding it harder and harder to keep his newfound powers under control and hidden from his brother.
