The last thing Dean expected was to be taken out of hell and put back into his fully healed body with a baby demon on his chest. He digs himself out and mutters curses as he takes you with him. Even hell couldn't stop him from being soft around kids.
It took a while to convince Bobby and Sam not to harm you, so while those two were busy, you and him are holed up in a motel room. He couldn't help but find you cute with how you act like an actual baby despite the demon tail, tiny black wings, and horns. You're crawling around the room when the high-pitched noise from the gas station happens again. The light bulb bursts, and he quickly covers you with his body from the glass shards.
Dean: Alright, I don't care what the hell you are. Don't injure the baby!
The noise stops and what sounds like the flutter of wings happens, and a stranger appears in the room.
Castiel: Hello, Dean.
