Season SummaryEdit

After spending four long, horrific months in Hell, Dean Winchester is miraculously raised from the Underworld and resurrected by an angel of the Lord named Castiel, one of several angels who appears throughout the season. After Dean reunites with his father-figure friend Bobby and his brother Sam, the rest of the season follows the brothers, with the help of Bobby, as they work with Castiel and his subordinate and friend Uriel, a fellow angel, to stop Lilith's plan of breaking the 66 Seals to unlock a cage in Hell, which will allow the release of the fallen archangel Lucifer, the Devil himself, who was once the favored angel of God but rebelled against Heaven for refusing to serve humans and therefore was cast down and banished.

Along the way, the boys meet a girl named Anna who not only has the ability to hear angels but is also a fallen angel herself. Eventually, angels turn up dead and the angels capture Alastair, Hell's Grand Torturer demon who seems to know Dean well, and they ask Dean to torture him with them assuming it's the demons killing the angels, but Alastair, before he dies, says it's not the demons. And eventually, Castiel learns that his own brother Uriel turns out to not only be working for Lucifer, but has convinced several loyalist angels to join him and to free Lucifer from his cage. Along the way, Dean learns that he broke the first seal while he was in Hell by being convinced by Alastair to slaughter innocent souls in the Underworld, especially when he reveals to Sam that he wasn't in Hell for four months but instead 40 years. Additionally, the brothers meet a Prophet of the Lord named Chuck.

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 kill Lilith. After tracking down and killing Lilith, Sam learns her death is actually the final seal and Ruby was deceiving him all along. Dean arrives too late to stop him, but the brothers kill Ruby as Lucifer's cage opens up beneath them and he is released upon the world
