(Imagine falling asleep in Sam and deans impala, wearing castiels trench coat)

You yawned, tired from running around with Sam and Dean all day. Castiel was in the back seat with you, he looked over to see that you had fallen asleep next to him. He was a bit confused for a moment, but then he did something unexpected, he took off his trench coat and laid it on top of you like a blanket. He pulled you to him and you slept on his lap, Sam looked in the rear view mirror and smiled to himself. Dean looked at Sam and then back at the road "what are you smiling at?" He asked. "Oh nothing, it's just.. Y/N fell asleep." explained Sam. Dean looked in the mirror for a moment and noticed you had fallen asleep on castiel's lap. It caused him to smirk, then laugh a bit. "What?" said cas. "Oh nothing, it's just I think she likes you cass. And getting a pretty girl to fall asleep on your lap...it's priceless." He said, then whistled. "And?" added cass. "And it's good luck.. and like dean said..it's priceless," said Sam.

Castiel looked down at you, watching you sleep. He thought you were beautiful and peaceful when you slept. He hesitated at first but he gently touched your long hair and began to stroke it, making you move a little in your sleep. For some reason it made him smile, and it made him feel something towards you, he said something in a very low whisper, "I think I love her."
