(1) Psych
Dean Winchester loved music, specifically classic rock. But whenever Sam Winchester was not in the car, Dean was known to branch out into less... image conscious choices. (Taylor Swift was showing up with a disturbing amount of regularity ever since that de-aging fiasco.) Therefore, Baby knew a lot of songs. Some she enjoyed a lot, others not so much, but as long as it made her boy happy she would deal.
Her parking lot mate was humming a tune she didn't know. While the little ditty was catchy, she hoped the tune wouldn't stick around.
Finally, the little blue Toyota Echo burst into fully voiced song. "I know, you know, that I'm not telling the truth. I know, you know, but you don't have any proof! Embrace the deception. Learn how to bend. Your worst inhibitions tend to PSYCH you out in the end!" It had a voice like a little kid's. Baby couldn't tell if the vehicle had grown into a gender yet.
"Nice tune, sweetie," Baby complimented in her most maternal tone. If the little blue ball of energy was older than a 2000 model, she'd be very surprised. Not a lot of cars that young had much in the way of personality yet. "You have a name?" Some cars get named right away by their drivers. Others have to decide for themselves once they've gotten self-aware enough. If this little one was singing, chances were it had gotten one of the two.
"Thank you!" It chirped happily. "I'm Blueberry. It's my other human's theme song."
"Blueberry. That's, ah..." Must be a girl's car, Baby mused. "...cute. Other human?" Baby asked encouragingly. The more a car talked with the youngsters, that faster they grew.
And maybe if they talked, Baby wouldn't get the song stuck in her head.
"Mm-hmm!" The Toyota enthused. "I have my driver, the guy the company gave me to, and my other human. My driver has a real job while my other human pretends to be psychic. Together, they solve crimes and save people."
"Pretends to be psychic? Oh, dear," Baby sighed. "My boys came to Santa Barbara because this psychic had a decent history of accuracy, so they thought he was the real deal."
Blueberry giggled. "Everyone knows that the supernatural isn't real!"
Baby chuckled warmly. Youngsters. They all learn soon enough what was really out there. And today would be this one's day to expand its horizons, because here came her boys. Two other men followed behind, one white and one black, both pretty young. The white guy was talking about how the his psychic powers worked. Huh. Apparently, Blueberry was a guy's car.
"Yeah, yeah, yeah, we get it. Not an exact science." Dean waved off more explanations. "Just tell us where this thing came from so we can clear out the rest." With that, he popped the truck open and stepped back to give the 'psychic' access.
Baby knew what was in the top half of her trunk, what the self-proclaimed psychic saw: A vampire's corpse with its detached head resting between its feet.
"Shawn! There's a body in their trunk!"
"Gus! I see the body in the trunk!"
"SHAWN! Why is there a body in the trunk?!"
"GUS! How should I know?!"
"SHAWN!"
"GUS!"
"BLUEBERRY!" the little car wailed in distress; every bit as high pitched, terrorized, and whiny as her drivers.
"Kiddo, why are you screaming your own name?" Baby asked gently, trying to keep her amusement out of her voice. The poor little thing was already a little traumatized, if it got much worse it'd have engine problems and electrical shorts for the rest of its life.
"Somebody should!" Blueberry wailed some more.
"You're going to be fine. Its alright," Baby soothed. The blubbering lessened, until Sam popped the trunk lid on the Echo.
"What was that!" Blueberry shrieked.
"Your trunk, honey." Baby explained patiently. "My drivers are going to put your drivers in your trunk-"
"DON'T!" Blueberry squealed. "I like Gus's head where it is."
"In your trunk, safe and in one piece, so they don't call the police before we have a chance to leave." Baby finished, still trying to calm Blueberry down. "No one's going to hurt them."
"It feels weird," the smaller car whimpered.
"I know, kiddo. I know. It'll be over soon."
"Baby?" Blueberry asked tremulously.
"Yeah, kiddo?"
"I think I leaked some gas."
