"It's OK, Baby. Don't listen to that heathen." Dean cooed to his car after Sam had once again told him to 'get a room' while climbing into his shotgun seat.
"You know, in all these years, I've never asked why you call her 'Baby'." Sam asked after closing the door with its distinctive squeak.
Dean turned to his brother with a stupefied look on his face. "What do you mean? She's always been called Baby." After seeing Sam's blank expression, he elaborated. "Don't you remember? Dad always called her that; for as long as I can remember."
"Did you ever ask him why?" Sam may have started this conversation to annoy his big brother but now he really wanted to know the answer.
"Yeah, I did once; when I was about 8 or 9." Dean replied as a far-away look crossed his face. "We were working on something, changing the air filter I think. He stopped what he was doing and just slowly smiled as he looked at me. Then he turned back to the engine and said 'it was your mother's idea'. He was real quiet for a long time after that."

"Dean sure does love the Impala, doesn't he?" Mary Winchester asked watching her young son grinning from ear to ear as he climbed into the backseat of their car.
"Ya think?" John replied while rolling his eyes. "What gave you that idea? The shrieking 'Pala 'Pala 'Pala since I picked up the keys?"
Mary groaned as another contraction started. "Well, if we don't hurry, his little brother or sister is going to be born in the front seat of his 'Pala'."
John Winchester carefully closed the passenger door after making sure his wife was safely in the front seat. He climbed into the driver's seat with a mischievous grin on his face. "I think that would be fitting. One born in the front seat, one conceived in the back seat."
Mary started laughing. "We can call her the Baby Machine!"
John turned the key in the ignition and the family car roared to life and he steered his growing family toward the hospital. "Or, just Baby, for short."
