Season 8 (Oct 3, 2012 – May 15, 2013)
Dean manages to return to Earth one year after going into Purgatory. By then, Crowley has found God’s Tablet that contains powerful spells that can close the gate of Hell forever, but also to unlock all of them and letting all the demons to roam the Earth. And the only person who can read them is Kevin. He escapes Crowley and was adroit enough to steal the tablet, only to be caught again and tortured to reveal the location of the other tablets. He is saved by Castiel, returned from Purgatory with the aid of some military force of a high-ranked angel named Naomi. She hypnotizes Castiel in being an informer about the Winchester boys. Samandriel, another angel rescued by Castiel reveals that there is also an angel tablet that can cause great harm to demons. Under Naomi’s bond, he kills the angel.
Henry Winchester, the boys’ grandfather, travels to their time to let them know that they are part of a secret society named Man of Letters, who categorizes all the supernatural beings. During this encounter, Kevin succeeds in translating the demon tables and informs all of them that there are three trials that need to be made to close the gates forever. Sam does two out of three, but because he has still demon’s blood in his system, the process is starting to hurt him. Kevin is again captured by Crowley, but the good news is that the boys find the angel tablet. Naomi orders Castiel to kill Dean, but the tablet breaks the connection and Castiel is free. He flees with the table to protect it, but Crowley tracks him down and steals it. Sam and Dean locate Metatron, who saves Kevin. He translates the last trial, which is to cure a demon. Unless they stop the last trial, Crowley threatens to kill everyone that the brothers ever saved. At this time, Metatron convinces Castiel to do the angel’s tablet trials to close the gates of Heaven.
The Winchester boys capture Crowley and make the third trial – curing a demon. In this time, Castiel was doing the angel trials, but Metatron is kidnapped by Naomi, who, after a session of searching into his head, she learns that the trials that Castiel was doing are part of a bigger spell that can expel all the angels on Earth, just like God made with Lucifer. She also discloses the fact that if Sam is completing the third trial, he is going to die. Dean was able to stop him just before that. Castiel returns to Heaven only to recognize Naomi’s dead body. Metatron traps him and stoles his grace, the last ingredient for the spell, making him human.
