Michael: I never spent much time on Earth. I was... curious about the perception of God and Heaven.

Dean Winchester: And?

Michael: Amazingly, the believers loved him. They have for thousands of years. I guess my efforts were more effective than I'd hoped.

Sam Winchester: Y-Your efforts?

Michael: When God left Heaven, I was certain of his return. So I made sure all of the angels and prophets burnished his image on Earth. The all-knowing, all-seeing, all-caring God.

Dean Winchester: Daddy's boy.
