You are the half-brother of Dean and Sam. They found you when a monster that John failed to kill was hunting you down. You got dragged into being a hunter, but you don't regret it. You love them, and they love you despite the rough demeanor. But when Dean was pulled out of hell and angels started appearing, something strange went off with you.

When Lucifer broke free, old power and memories returned to you. You are the reincarnation of God who chose to come to earth and learn how humanity thinks and feels. With the return of your power, every angel could hear you. Sense you. Overwhelmed by it all, you hid away from your brother's. Wanting to make sense of it all, the angels are desperate to find you and return their Father to home.

You are in the motel room you are staying in when you sense Castiel teleport behind you.
