"Really, Sam?" Dean was not a happy camper. "Did you have to ride her that hard through the dirt? Look at my Baby... she's soiled from roof to rims."

Angrily the older Winchester trudged around his beloved Impala, which was covered with a fine sheet of reddish dust. Dean hadn't been happy to start with that Sam wanted him to stay put when he went to salt and burn the remains of the Griffin. He had only relented when Mary backed Sam up. But, if he was honest, he was still feeling all of his encounter with the Griffin. His arm was hurting - and itching, his head was pounding and even spinning at times. Dean had been asleep when Sam and Mary returned from their mission.

When he had seen his beloved car in the morning, he was ready to strangle his brother. It wasn't like they had been on the run. The corpse wasn't going anywhere, no cops or monsters on their heels. Why couldn't he have driven slow enough not to stir up the dust on the ground?

"I'll help you clean her," Sam offered, but Dean just snorted.

"The hell you will. I'm not letting you near her till I know she's alright," Dean growled and pushed past Sam, running his fingers lovingly over the classic's frame, only to frown at the marks they left.

"Dean, you're not..."

"If you say I'm not up to it I'm gonna deck you," Dean snarled. Mary put her hand on Sam's arm.

"Let him be, Sam," she said soothingly. "Give him some space."

Reluctantly, Sam let Mary pull him away. They went inside where Mary started getting things together to have everything ready for breakfast when Cassie returned from the shop.

"Can I help?" Cadie popped up next to Dean when the other Winchesters were gone. Dean turned to study her a moment.

"Can you bring me a soft cloth?"

"Sure," Cadie turned to get back inside. A few minutes later she returned, dangling the desired fabric in front of her. "I brought two, so I can help."

"Cadie, I..."

"Look, I know. She's your Baby. But I didn't scratch her paint with the lock pick, what makes you think I will do so with a cloth?" She crossed her arms and cocked her head, daring Dean to deny her. Dean raised an eyebrow and then shrugged.

"If you put it like that, you can start with the trunk." Dean smiled to himself, a gesture that didn't escape Cadie. Happily she reciprocated the expression.

***spn***

Cassie pulled her car into the driveway, squinting at the picture that greeted her. Dean's Impala was filling most of the space, which was why she had barely pulled in. What puzzled her was seeing her daughter busy with the trunk. Cassie knew how possessive Dean was when it came to that car so she cut her engine and opened her door to get out.

"Cayenne Dean!"

Cadie's head shot up, eyes wide, as she stared at her mother. Cassie almost laughed at her expression that was so much like a toddler caught with the hand in the cookie jar. It was always amazing what reaction one got when calling the kids on their full names. Her smile faded somewhat when a second head popped up from the front of the black car.

"Heya Cassie," Dean greeted. "Didn't think you could see me from there."

"I couldn't," Cassie replied, tone somewhat contrite. Dean frowned and tossed the cloth he was holding onto the hood.

"Okay," he dragged the word, trying to buy time to make sense of it. His slightly hurting head didn't really help much. "Then why did you call me?"

"She didn't call you," Cadie explained, hands fiddling with the cloth in her hands. "She called me."

Dean blinked, looking at her, then let his gaze travel back and forth between Cadie and her mother, brain slowly registering the implication of those words. He scoffed.

"Right. I think you better run that by me again, cos my brain isn't working so great right now."

The three were standing a moment in silence, Dean trying to process the yet unconfirmed news, Cassie trying to figure out how to not make it sound too bad and Cadie feeling trepidation closing in on her. Finally Dean looked up, clearing his throat.

"So, Cadie is...?" He trailed off, eyebrows raised.

Cassie nodded. "Yes."

"And she knew it." It wasn't a question, really. Dean glanced at Cadie, catching tiny nod from her. The girl's eyes were big, and Dean understood she was scared.

"Wow," he said, taking a deep breath. Then he picked up the cloth again and resumed polishing Baby's hood. After a few moments however, he paused and looked pointedly at Cassie. "When were you going to tell me?"

Cassie sighed and stepped closer, relieved when Dean made no move to back away.

"Cadie? Go get the bags from the car, honey," she told her daughter. Cadie nodded and handed her cloth to Dean before complying to her mother's request. When Cadie had entered the house, Cassie put her hand over Dean's, that was resting on the hood. Dean looked down at their hands, a warm feeling washing over him.

"I gotta be honest, Dean," Cassie started, making Dean lift his head to look into her eyes. "I didn't really plan on not telling you. The timing was just never right, I had no idea how you'd react and eventually time passed and things would have been more akward."

"Cos they aren't now?" Dean asked, voice rough with emotion. Cassie laughed briefly.

"Yeah, they are," she conceded. "But we have to deal with it now. You... don't look too upset?"

"I'm not upset, Cassie. Just stunned. I think I need a drink," Dean smiled shyly.

"No, Dean. No drink. You have a concussion," Cassie puffed indignantly. Dean shrugged.

"I need something to settle my nerves, it's not every day you learn you have a spitfire 11 year old daughter."

Cassie nodded, grinning like a Cheshire cat. "I might have an idea." She closed the gap between them and pressed her lips to his in a short, sweet kiss. When she broke it, Dean reached out to her to pull her close again.

"I might need more of that," he said with a dazzling smile.

"So... you're really not mad?"

Dean became serious once more. "Well, no. Can't really blame you, sweetheart. But I have to admit, I kinda suspected it."

"I'm actually surprised she didn't tell you before," Cassie admitted. "So, what made you suspect?" Dean smirked and then rubbed his forehead absentmindedly.

"Well, at first I thought she was younger. She sounded younger on the phone. Truth be told, I was a bit jealous then. But when I saw her and she told me her age... well, the notion was there. Oh... and the fact that she broke into Baby's trunk..."

"She what?" Cassie exclaimed.

"Ask Sam if you don't believe me," Dean nodded. Then he looked over his shoulder at the front door on the porch, where Cadie was standing in the frame, watching them. "She's a good kid. And I'm kinda proud she's mine." He inclined his head to steal another kiss from Cassie. "Let's go inside. I'm starving."

Breakfast was a noisy affair. Cadie chatted away between bites and sips, Sam tried to keep up with her when in reality he just wanted his brother to drop his grudge over him getting the Impala all dusty. Cassie and Dean kept staring at each other, back to their old game of trying not to get caught doing so by the other. It was driving Sam nuts. Something had happened since his brother detected his violated car. Mary was quietly trying to take in as much as she could. She was watching Dean, then Sam, before deciding something had to be done.

When Sam and herself had driven out to take care of the Griffin, Mary had asked Sam to tell her about Dean and Cassie. She knew they had the hots for each other last time they were there on the case involving Cassie's father. And from Sam's words she learned that it wasn't their first time and that Cassie knew in what line their job was laying. She knew about ghosts and other supernatural beings, she might as well learn the other aspects of their trade.

Dean's body language was a mixture of hiding pain from his injuries and devouring Cassie with his eyes everytime she looked somewhere else but him. Sam's posture was tight, on edge. He felt bad about his brother being hurt, and about Dean blaming him for Baby's current state. Yet Mary could sense there was a vibe of being playfully annoyed at the turn things were obviously taking between Dean and Cassie, as well as curiosity about what the two had been talking about outside. Cadie was excited, giddy, chatting away with her mouth full until she got reprimanded by her mother.

"Alright, kids. I think it's time to come clean with some things," Mary broke the sociable chatter when everyone had finished eating. "We've had a few eventful days and I think everyone here might have some unanswered questions, that probably should be cleared up sooner rather than later."

Sam and Dean both looked a bit panicked at her words, but they knew she was likely to be right. Secrets were neccessary. But they were also awkward between trusted friends. Cassie joined them in looking at her and even Cadie stopped flicking some crumbs across the table with her thumb and index finger.

"I'm not really their cousin," Mary explained, looking at Cassie and her daughter. Cassie frowned.

"You're not? Then who are you to them?"

"I'm their mother," Mary simply supplied.

"Their m... wait. Wait, wait, wait." Cassie was confused, not sure she heard right. Cadie made big eyes, studying Mary anew. Cassie took a deep breath and held it for a moment. Then she looked Dean squarely in the face. "You told me your mother died in a fire when Sam was only a baby." There was no malice in her voice, only genuine confusion.

"She did," Dean responded, keeping eye contact.

"But...?" Cassie pointed at Mary and shrugged.

"Cassie, baby, there are things and forces in this universe that you don't know anything about. You know about some, like ghosts, or this Griffin now. But those are merely the tip of the iceberg. And I'm talking Titanic sinking iceberg." Dean started explaining. "It will take a long time to get to know it all. For now you and Cadie should know that since we've last been here, both Sam and I died a few times over."

Cadie gasped, mouth ajar. Cassie's frown deepened.

"There are powers at work that have control over life and death. Witches. Demons. Angels..."

"Angels are real?" Cadie's eyebrows shot up. "So you weren't joking about the angel feather." She looked at Sam who shook his head in confirmation.

"Yes, Cadie. They are. We helped set things right between two ancient, very powerful... entities... and as a thank you of sorts, they brought Mom back. After thirty odd years of... being dead."

"Wow," Cassie said after a few moments of silence. "That sounds... unbelievable. Mary, things must be so weird for you."

"They are, honey, but I'm adjusting," Mary smiled. "It's kinda hard at times, however, like one minute having two small boys and the next moment you recall, they've grown into tall young men with a liking for hunting."

"Which brings us back to playing with an open deck," Dean jumped in before Cassie could question Mary further. "Mom?"

Mary looked up and into her oldest son's eyes.

"The other day you were asking about grandchildren? You got one now, in Cadie."
