The Castiel Mistake

While traveling on his own, Castiel encounters someone by the name of Anika, an angel who still blames Cas for the falling of the angels. While trying to convince her fighting will solve nothing, Anika attacks Cas. Pushed to his limit due to Anika having more grace, he is shoved into a wall that crumbles on contact. Slightly disoriented, Cas gets up and looks at his surroundings surprised to see he is at a television set. On the way around the set, he finds two men who he assumes are Sam and Dean. Boy was he wrong. Sam and Dean are only the characters Jared Padalecki and Jensen Ackles play on the television show Supernatural. Castiel is taken to his supposed dressing room by the confused actors to find that Misha Collins is already in there. Cas explains his issue and is shocked to find that his grace is still intact, due to Anika performing the spell incorrectly. The only problem with this, Cas can't get back. Will he get back to his own world before J2M bring back "broken" Cas?
