 They manage to complete the second trial (retrieving the bow of a cupid), but Metatron subsequently reveals that his true intentions are to exile all the angels from Heaven for forcing him to leave Heaven ages ago.He takes Castiel's grace from him as the third ingredient for this spell, leaving Castiel human and banished to Earth before the other angels begin to fall as well.With the angels expelled from Heaven, many of them begin searching for Castiel, whom they believe is responsible, and was knowingly working to enact Metatron’s plans.
