Stefan Salvatore

When Dean awakens and climbs out of his coffin, he does not know who rescued him from Hell. Castiel tries to 'speak' to Dean after his resurrection, but all Dean hears is a piercing sound. When Pamela Barnes conducts a seance to reveal the being who saved Dean, she reveals that it's name is Castiel. Pamela orders him to appear and attempts to catch a glimpse of him. Castiel warns her off, but she persists and is blinded when she encounters him psychically. Again, while Dean is alone in his hotel room in Pontiac, Castiel tries to speak to Dean, but his 'voice' shatters all the glass in the room...
