It seems they've been having final exams on  monsters and spells this season. In this episode, they seem to be hitting all the parts of human experience that Sam and Dean had missed. Castiel didn't need this lesson, he lived it, with his powers lost, living homeless trying to stay alive, and then working at the gas and sip. He's also been a sidekick in need of rescue,

I notice Sam Dean and Castiel are yet again playing a shell game, two in one place, one in another.
