 However, Castiel is instead seen with a very alive Crowley who states that he is "tired of cleaning up after [Castiel's] messes", implying that Castiel had full knowledge of burning the wrong bones and that both he and Crowley have some sort of agreement between them and/or may be working together as partners.In "The Man Who Would Be King", it is revealed that Castiel was the one who partially raised Sam from Hell, though due to the complication of the cage it was impossible to retrieve his soul, and that he has made a deal with Crowley in a desperate attempt to win the war.Sam and Dean also learn of his partnership with Crowley when he slips up and reveals he is spying on them.
