Everyone knows that when Dean refers to "his baby," he means the Impala. Everyone but Castiel.

Castiel was very confused. Castiel was usually confused around the Winchester brothers. But this time was different. Actually, this time wasn't that different but it was different in regard that it had been weeks and Castiel still didn't know what Dean was talking about. Usually he understood what Dean was talking about after a few days or Sam took the time to explain it to him. Castiel never really got the chance to ask lately.

"Don't you douche her up!" Dean ordered Sam.

"My baby better not have a scratch on her when you come back!"

"You hurt my baby, you're dead!"

"Don't play your stupid music with my baby there!"

"Dean," Castiel said.

"What, Cas?" Dean grunted.

"You have a child?" Castiel inquired.

"What? No! Where the hell did you get that idea?" Dean sputtered.

"You keep referring to 'your baby' and 'her.' You must have a child," Castiel insisted.

"Cas, how long have you known me?" Dean asked.

"Forty-eight days, seven hours, and thirty-three seconds," Castiel said. Dean blinked. He hadn't been expecting that one.

"Uh, right," Dean said. "In all the time you've known me, have you ever seen me with a kid?"

"No but why would you keep mentioning a child?" Castiel frowned.

"The Impala, Cas! The Impala is my baby!" Dean said.

"You cannot give birth to a car, Dean. It is impossible," he said. Sam came in and then Dean got up, snatching the keys from Sam.

"You deal with him," Dean ordered.

"What's going on?" Sam asked when Dean slammed the door.

"He thinks that he has given birth to the Impala," Castiel said, tilting his head.
