Season Summary
4 Months after Dean's death, Dean is rescued from Hell and brought back by an angel named Castiel, one of several angels who appears throughout the season. Now back from the dead, Dean searches out Sam, who now is living the hunter lifestyle. Now reunited, the brothers begin hunting again, but not everything is the way it used to be. In addition, their demon "ally" Ruby, is still alive. The rest of the season follows the brothers as they work with Castiel to stop Lilith's plan of breaking the 66 seals, which would allow Lucifer to walk free once again.

But nothing is the same as before. Both brothers are keeping secrets from each other. Sam and Dean's relationship is also strained as Sam starts siding with Ruby over Dean. He also begins to give into his demonic side by drinking demon blood to become strong enough to defeat Lilith. While Dean hides the fact that he does remember hell and regrets the things he did there.

Then the brother's relationship finally cracks, and Sam chooses Ruby over Dean. After tracking down and killing Lilith, Sam learns her death is actually the last seal and Ruby was deceiving him all along. Dean arrives too late to stop him, but kills Ruby as Lucifer's prison opens up beneath them.
