Castiel deposits Dean back on the bed, and looks down at him for several moments, considering.

This is uncharted territory, and Castiel is beginning to doubt his ability to find his way alone. He is not sure he has the capability to help Dean by himself.

Castiel needs help. He knows he has help for the asking.

And Dean is not going to come around again for a while.

Castiel leaves the room, locking the door behind him.
