Ten year-old Dean sat cross-legged on his bed on a Friday afternoon, staring at his math worksheet. Why can't my homework just do itself? Dean thought. I don't get what I'm supposed to do with this long division.

"Dean!" Dean heard his name being called from downstairs. "Dean!"

It was obviously John. Dean went down to see what was up.

"What is it, Dad?" Dean said, coming into the room. "Did something happen?"

"I need to go on an emergency hunt in a forest ten miles from here. It shouldn't take too long. If all goes well, I'll be back in a few hours, but I need you to watch your brother while I'm gone."

"Sure, Dad," Dean said, never one to ask lots of questions. "I'll do that."

"I don't need to be looked after!" Sam cried out, indignant. He was six years old, for God's sake.

"Yes, you do," John said simply. "Not because you're a baby, but just because you're not old enough to stay home by yourself. So, be good, okay?"

"Fine," Sam said quietly.

"Good. Now, I have to go. Dean, remember, keep an eye on Sammy. And no nonsense. I'm serious, Dean."

After John left, Sam turned to Dean. "So, what do you want to do, Dean?"

"I want to get back to my math homework…"

"Come on, Dean, Dad's gone. We can do whatever we want now."

"Except that we can't since I have a whole math worksheet to finish. Besides, we can't do anything fun because Dad made it pretty clear that we are not to get into any trouble while he's gone. Remember last time?"

Sammy cringed. Of course he remembered. That was when he and Dean started a game of catch in the motel living room. They ended up breaking a lamp and getting kicked out of the motel. John's yelling was still ringing loud and clear inside both of their heads.

"Well, we don't have to do that, again," Sam shrugged. "Let's just go outside for a little bit. Then you can go back to doing your homework."

"Sammy, that's not a good idea…" Dean started, but was unable to continue further. The thought of going outside was tempting.

"Come on, Dean… One hour?"

"Fine!" Dean agreed. "But you better not whine for five more minutes when I say that it is time to leave."

"I won't!" Sammy smiled. "I'll just get my coat and then we'll go out!"

Sam and Dean got dressed and then walked to the nearest plaza, where there was an arcade, a playground and a McDonald's.

"OK, Sam," Dean said once they got there. "What do you want to do now?"

"I want to go on the playground!" Sam cried out. "Come on, Dean!"

"Fine," Dean said, trailing behind. He had a bad feeling deep down in his stomach that something was going to go wrong. Things always went wrong when he disobeyed his dad's orders.

But nothing seemed to be going wrong. Sam and Dean played on the playground for a long time before it was time to go home. Dean was constantly checking on his watch, making sure that they were not gone for more than an hour. At that moment, however, Dean heard his name being called. He noticed a girl from school, Natalie Jensen, coming towards him.

"Hey, Dean," she said. "Are you here with your little brother?"

"Yeah," Dean smiled. He had always liked Natalie.

"Well, I'm here with my little sister, Angela. Do you want to go get ice cream at McDonald's while they play together?"

"I do…" Dean said. "But I'm supposed to be watching Sammy."

"I can stay here by myself!" Sammy cried out. "Come on, Dean, we don't have to go home just yet!"

"No, you can't," Dean argued. "Did you not hear what Dad said earlier?"

"Well then, how about we take them with us? They can get ice cream too."

"Yeah!" Sam cried. "Let's do that!"

It was decided, then. The four of them went to the nearest McDonald's and got ice cream. They sat down in a booth with their cones and started talking. Well, Dean and Natalie did, anyways. Sam and Angela started getting bored.

"Dean?" Sam called. "Dean, Dean?"

"What?"

"Can Angela and I go to the kids play zone?" Sam asked, glancing at the Ronald McDonald play zone.

Dean glanced at Natalie. "Sure," she said. "I mean, we'll be right here. Just don't go anywhere else."

"Well, I guess it's okay, Sammy," Dean said, glancing at his little brother.

"Yay!" Sammy cried out and ran off towards the playground. Dean and Natalie went back to talking.

"So, Dean?" Natalie asked. "What kind of T.V. shows do you watch?"

Natalie and Dean talked for a while, spending some time discussing each other's interests and laughing about some of the funny things that happened at school. Dean had almost forgotten about the fact that he and Sammy were supposed to be starting the walk home pretty darn soon until one of the store's workers came up to him and tapped him on the shoulder.

"Excuse me, son, but is that your brother over there at the playground? He keeps calling for you."

"Yeah, that is," Dean said, glancing at the playground and seeing Sammy, sitting on the side crying. "Did something happen?"

"I'm afraid it did," the employee shook his head. "The little one had fallen off a slide. We think that his arm could be broken."

"What?" Dean burst out. "Is he alright?"

"He's fine, but we do need to take him to the hospital as soon as possible. Is your mom or dad at home? Because we need to reach one of them."

Dean listened to all of this, in shock. He glanced at the playground a second time and then noticed that there was a cluster of people around his little brother, talking to him gently. He also noticed that his left arm was twisted into a crooked shape, something than an arm should never look like. Dean quickly got up and ran towards his brother. Natalie and the McDonald's worker followed him at his heels.

"Sammy? Sammy? Are you alright?" Dean asked over and over again.

"Deannn…." Sammy moaned. "Hurts."

"Son, you're going to need to step away. We need to get your brother into an ambulance," Dean noticed that all of a sudden, a paramedic appeared on the scene. "You can ride to the hospital with him, okay?"

"Okay," Dean said, not knowing what else to say. "I will."

"We're going to come too," Natalie said, taking Angela's hand. "I'll call my mom from there."

"Okay, then," the paramedic said. "Let's go, kids. We'll all call your parents when we get there. But do not worry. Little Sammy here is going to be just fine. They'll put a cast on him and then he'll be good as new."

"I hope so," Dean said, starting to cry. "I hope so."
