Dean – 17

Sam – 12

Kate – 9

"Deeeaaannnnn," Kate whined as she sunk down into her seat in the back of the Impala. "How much longer is this going to take?"

Not even fazed by the question—asked for the tenth time—Dean kept his eyes forward on the hardware store entrance and replied sarcastically, "Until Dad's done." Because honestly, that was the only answer he had. John decided to drag them out the door 20 minutes earlier this morning to run two errands on their way to school. John saw it as being efficient to use the trip into town to pick up supplies on the way, especially since their motel was on the complete outskirts of town, but in reality, it just made for an extra grumpy set of siblings.

Kate groaned in response, folding her arms. "This is ridiculous."

Sam didn't take his eyes off his chapter book. "You're ridiculous."

Now that got her attention. She shot back up in her seat and turned to the evil brother, never able to pass up a chance to get back at him. "You wanna say that again to my face?" The phrase sounded strikingly similar to something her eldest brother would say. It wasn't anything new to this family, but the two of them always seemed to be at odds for some reason. One of them breathing the wrong way would set off the other. It seemed that they'd just fight to fight—as if it had already been engrained in them that they weren't friends.

With eternal patience, Sam placed his bookmark and closed the book. "I said you're ridiculous. All you do is whine like a baby!"

Dean rolled his eyes, but his sister had to respond. "Yeah, well, you're as ugly as a freaking orangutan."

Sam chuckled, only making Kate's blood boil more. "Orangutans are the smartest primates, only after humans that is." He smiled proudly at his rebuttal.

"Yeah, well that don't make them nice to look at!" She stuck her tongue out for good measure.

Normally Dean had learned to block their stupid arguments out, but the second he saw John exit the store with a bag in hand, he knew he had to intervene. He turned around and scolded quietly, "Knock it off before Dad gets in here."

But Sam wasn't having it. "But she literally started it, Dean!" He was fed up of getting dragged into her childish insults and games and always taking the blame for it.

"Cleary you're not as smart as you think you are because YOU started it!" Kate retorted.

Dean turned all the way around in his front seat. "Guys!" he hissed, this time with more urgency as John approached.

The two younger siblings' eyes were locked in what would be an eternal battle if there were no immediate intervention. Sam opened his mouth to sling another insult her way, but before he could get anything out, Dean did the only thing he could think of to get him to shut up before John got in the car. He smacked the back of Sam's head.

"Ouch!" Sam hissed, instantly rubbing the point of contact. Now his anger was quickly shifted to his stupid older brother. He pulled back his own hand to retaliate and launched it in Dean's direction at the same time the driver door opened. By that moment, Sam was already committed to the action and his reflexes weren't good enough to try and reel it back in in time. However, Dean's well-developed hunter's reflexes allowed him to catch Sam's hand just before it made contact, gripping onto his wrist with a death glare.

John had seen enough by the time he sat in his seat and Dean released his brother's grip, trying not to make eye contact with their father. John placed the plastic bag on the seat and turned to Sam with a set jaw. "You acting up, boy?" he asked in his no-nonsense voice.

Sam felt his cheeks flush with a mix of embarrassment and frustration. Why was it always him who got in trouble lately? He wasn't the only one who was involved, but it seemed John only ever saw the middle child doing wrong. At least, that was how it felt to him. Before Sam could muster up the courage to reply, Dean jumped in, wanting to smooth over the situation. He added carefully, "We were messing around, Dad. Won't happen again."

But John Winchester's patience was gone for the day. He wasn't a man known for displaying much of it anyway, but he did have a small, some would say minuscule, reserve of patience for his kids. However, they'd blown through it like a bomb an hour prior when Kate and Sam had fought endlessly over who got to use the bathroom first. John Winchester wasn't having this again today.

John slowly turned to his eldest. "Was I talking to you?"

Dean gulped, knowing he'd overstepped. He replied quietly as he sunk into his seat, "No, sir."

Satisfied, John returned his attention to his longer haired son. "I'm waiting, Samuel."

Sam felt his insides churn at his full first name, and Kate was silently thankful that she hadn't been the one caught. He took a deep breath and replied, knowing there was no way out of it, "We were just playing around. We weren't fighting."

John's eyes narrowed as if he were trying to see inside Sam's head. He momentarily looked from Kate to Dean and then back at Sam. Seeing no other evidence to point out the contrary, he replied in a stern tone, "I see it happen again, and you'll be sorry." John let the threat hang in the air as he turned back around and started the car up, ready to drop them off so he could go about his day in peace.

Sam just sunk down in his seat, willing the car to get to school faster than ever. Nothing about this was fair.

School was just like any other day of the year for the Winchester kids. To one, it had been pointless, to the other it was boring, and to the last one, it was repetitive. When the Impala pulled up in front of the school, the three siblings headed for the car, with Kate rushing past Sam to beat him to it. Once she successfully reached her destination, she gripped the door handle and turned to her brother walking up behind her. "Beat you," she mocked with a grin.

Sam shrugged, trying very hard not to be mature and not take her bait. "I wasn't trying."

Still content that she won, Kate hopped into the car. "Hey, Dad."

John gave her a welcoming grin back. "Hey, munchkin." The old and familiar nickname made her smile. Once the other two were settled in, he added, "I got another errand to run before we head back. Shouldn't take long." He had been out and about all day, trying to restock their entire supply, and it always took a few stops to get everything done. His plan was to have everything finished by the time school let out, but the lunch stop at the bar didn't help anything. One last place for ammo and he'd be able to put the errands behind him.

The father was pleased, albeit shocked, that there were no protests about the after-school pit stop, especially after he'd made them get up earlier that day to do just the same. Maybe they'd learned their lesson this morning after all.

John had been inside the store for about ten minutes when Sam decided to get his math homework out and start working. If he was going to be forced to sit in this car for who knows how long, at least he could get some work out of the way.

About ten minutes later, John returned to a silent car, each kid doing their own thing whether it be homework or staring at the window to people watch. There was just something about silence that was like music to his ears.

However, all silence must come to an end.

About five minutes from home, John was unable to avoid a pothole in the road and ran over it, causing the car to bounce harshly. As a result, a few pencils and folders fell out of Sam's backpack that was sitting beside him on the seat. Kate couldn't help but groan quietly that now his crap was invading her space and touching her. That jerk. Although it defied logic, she just knew that he did it on purpose.

Without saying anything, she harshly shoved everything back on Sam's side of the imaginary divider in the backseat. Sam finished writing his answer and then looked to his left at what she was doing, acting as if it were his fault that it happened. His lips formed a determined line as he shoved his folders back ever so slightly, so they were hovering in the middle. He'd tried not to get down to her fighting level per usual, but if anyone knew how to push his buttons just the right way, it was his freaking little sister. And he couldn't let her win like she always did.

Well that just couldn't be. Kate shoved on the folders again, but Sam quickly stepped in and pushed right back. For an infinite moment, they were both pushing on a folder in a silent battle of "get it away from me." John happened to glance in the rearview mirror and could see the set determination on their faces as they were doing whatever it was they were doing. He knew that it would eventually blow up, that was how it worked with these two, so he said a simple warning to his middle child, already holding him to a different standard than his youngest. "Sam," he called out sternly.

Sam's hair flopped as he looked up at his dad, aggravated that he had only said his name when there were clearly two locked in this battle. Sam's sudden loss of concentration allowed Kate's full force to shove the folders into his side as he let out a small yelp from the suddenness of it. Now pushed over the edge, Sam no longer cared that his father was noticeably watching. He picked up the folders, gripping them with both hands and then brought them down to smack Kate's leg with a very loud whack!

It had happened so fast that nobody had time to react, except John, who had already managed to pull the car over on the side of the country road. He cut the engine as Dean turned around to see what the hell was going on. Kate was rubbing her leg and glaring at Sam, who looked guilty holding the damn folders. But at least the two of them had enough sense not to speak. Because when John Winchester pulled over the car, there was no going back. They knew it was bad.

"Sam. Out."

It was two words. Two words that gave Sam his fate. Of course he was the one who was going to get his ass whipped on the side of the road. His sister could get away with murder, or more likely yet, he'd be blamed for it.

"Now."

John instantly got out of the car, slamming the door behind him in sheer frustration. Dean's worried eyes quickly went to his little brother. Even he knew how bad this was—and the worst part was he couldn't fix it. He gave Sam a quick look of pity and said, trying to give him some kind of lame ass pep talk, "Just take it like a man, Sammy. We, uh, we won't watch, okay?" Because the only thing worse than getting an ass kicking on the side of the road was having your siblings be in the front row.

Sam glared from Dean back to Kate, now enraged that this was all happening to him. He didn't say a single word before exiting and dragging his feet toward his dad, who was waiting about fifteen feet in front of the car.

Once Sam was standing squarely in front of him, John reached down and harshly gripped his chin to make his son look him in the eye. The father didn't waste any time before verbally ripping into him. "How many damn times do I have to tell you to stop fighting with your sister? It's like you purposefully want to disobey me, boy."

Sam opened his mouth to add that it wasn't him who had started it but the deathly look John gave made him snap his jaw back shut.

"You're going to be thirteen next month, Samuel. You're a grown man and have responsibilities to this family, and yet I can't trust you not to get under her skin. How the hell do you expect me to leave you two alone when we're on a hunt if you can't take care of your sister, huh? You're acting irresponsible and I won't have it anymore."

Sam's eyes darted to the ground at how inadequate he was now feeling, but a rough jerk from his grip made his eyes quickly rebound to his father. Sam knew he was supposed to take care of his sister, but he wasn't an adult so his mind didn't quite function that way. The little brat knew how to get at him like nobody else in this world. But that wasn't what his father wanted to hear. He knew exactly what he was supposed to say, and so he did just that, to not dig his hole any deeper. "I'm sorry, sir. I'll do better next time."

John's eyes bore into him for what felt like an eternity. He released his grip harshly and held a finger up to his son's face. "Damn straight you will." And then he ran the same hand down his face to try and calm himself down before he lit into his son. He slowly looked to his right and left, taking in the abandoned road they were on. And suddenly it hit him—he had a much better punishment to fix this. "Don't you dare move," he threatened before taking off back toward the car.

Sam bit his bottom lip to keep it from quivering. Whatever John was going to get from the car, it couldn't be good.

Once Sam had closed his door to go meet his fate, Dean whipped his head toward his sister. "Seriously, Kate?! Can't you two keep the peace for more than five minutes?"

Kate couldn't meet her brother's eyes, knowing she was at fault, too, but that didn't mean she wanted to admit it. "He's the one always bothering me."

"Yeah, well, you just make it worse."

She crossed her arms at the accusation and looked out the side window. "No I don't."

Dean scoffed, "Think about it next time, Kate. Sam's out there because you two can't learn to play nice. Next time it's probably going to be you, so you better start acting right."

At the mention of "out there," Kate couldn't help but look out the windshield and see John firmly gripping Sam's chin. Her chest filled with a new wave of guilt. She knew what it was like to be on the receiving end of the Riot Act and wouldn't wish it on her worst enemy.

The two sat in silence as they watched it all unfold in front of them, Dean determined that they'd look away if it started to go south.

However, something happened that neither of them expected. John started walking back to the car, leaving Sam standing where he was.

Fully expecting John to go to the trunk, Kate was surprised when John opened her door instead.

"Out."

And her fate had now been decided.
