An hour later, Dean and Sam were running through an obstacle course, drenched in their own sweat. Their father had put together a challenging course togehter-it included running the tires, doing fifty sit ups, running windsprints, and escaping from a locked trunk. By the time Dean was finished with his windsprints, his lungs were on fire.. He was coughing again, more than ever; He was feeling lightheaded, and all he wanted to do was lie down-but he couldn't, or his father would just tack on more challenging events.

After he had managed to open the locked trunk and escape-his final challenge-he promplty walked over to a tree, leaned behind it, and threw up.

"You okay, Ace?" John asked, handing his son a water bottle. He looked over his son-Dean was a bit pale, but he chalked it up to exhaustion. He decided that he would let them rest for the night once they were finished with the next part of the challenge.

"Yes, sir," Dean answered, rinsing out his mouth. "It must have been something I ate. Don't worry, I'm ready to move on."

"You sure? Because you can come home and we'll finish the rest of the course later," John offered. He typically didn't let his sons chicken out-but Dean looked sickly, and Sam was coughing too.

"No thank you, sir," Dean answered. He didn't want to seem weak in front of his father or his brother. "I'll be fine."

"Are you sure?" John asked.

"Yes, sir," Dean answered. He wiped the sweat from his face, plastered on a smile, and asked, "So, what's the next part?"

After a five mile run that felt more like a fifty mile run, Dean and Sam reached a solid rock wall. It was at least fifty feet tall, and jagged-it looked threatening. Dean knew what his father was thinking, and he didn't like it a bit.

"You're climbing it," John told his sons, reaching in his bag for the safety equipment he brought.

Dean looked at Sam-the poor kid looked terrified. He was terrified of heights-had been ever since he was little.

"Come on, I'll hook you up," John told his sons. "Dean, you first."

Dean stepped forward and pulled on his harness. He tightened it, and made sure he was prepared.

Dean looked up, ready for his father to check his knots-but he didn't. John was busy helping Sam tie his knots and tighten the harness. Dean figured that he would be alright-he had tied these knots hundreds of times-he would bee fine.

"Okay, Ace, let me clip you in," John attached Dean to his belay cord. "Watch out for your brother up there, okay?"

"Sure thing, Dad," Dean looked over to Sammy, who was trembling. His face was white as a sheet-he looked like he was giong to pass out.

Dean walked over to his brother, determined to calm his nerves. "You okay?"

"I hate heights, Dean," Sam answered, peering up at the rock wall. "What if I fall?"

"You're not going to fall," Dean assured his sibling. "Dad has you hooked in tight."

"Are you sure?" Sam queried, looking over at his big brother.

"Of course I'm sure," Dean answered, his voice confident. "I've got your back up there, baby brother."

"THanks, Dean," Sam replied. He was a bit more willing to climb up the wall now-he trusted Dean.

"You guys almost ready?" John asked. They only had a couple moe hourss until dark-he didn't want them getting lost in the woods. "If you want to have time to do some belaying, you're going to have to start."

"Yeah, Dad," Dean answered. He flashed Sam a reassuring grin, and then took the first step up the rock wall.

It was slow going, but soon they were halfway up. Dean decided to stop for a minute-he couldn't stop coughing, and it was hard to breathe.

"Dean? Can I try belaying?" Sam asked. Once they were off of the ground, he had become less frightened-he was almost daring.

Dean thought it would be perfectly safe for Sam to attempt it. So he nodded, and said, "Sure, Sammy."

Sam leaned back and kicked off of the rock wall quickly, with far too much force-and without warning his father, so he could feed the line.

Within seconds, Sam was freefalling, and John was struggling to grab onto the line.. Dean watched in horror as Sam fell down two stories, screaming the entire way.

"SAMMY!" He screamed. He couldn't see or hear his baby brother any more-was Sam dead?

But then, he heard sobbing, and he breathed a sigh of relief. Sam was concious, and responding-he was awake.

"Dean, Sam's going to be okay!" John shouted up at his eldest as he kneeled by Sam's side. John had managed to grab the line when Sam was about six feet from the ground; he wasn't able to stop the kid from falling, but it was enough to stop him from hitting the ground at full impackt. He looked at his son-his arm was sticking out at an angle, and his leg looked like it was broken.

"Daddy, it hurts!" Sam cried, reaching out for John. John almost froze-Sam hadn't called him Daddy since he was four years old.

"I know, Sammy, but you have to stay still, okay?" John reminded his youngest. John didn't want to risk paralysis if Sam aggravated a neck injury.

"Dad, I'm coming down!" Dean yelled, panicked. Sure, his brother was awake, but he was also in pain.

"Sam, do you want Dean?" John asked.

A tear rolled down Sam's face, and he said, "Please."

"Alright, Dean!" John shouted up at his eldest. "Go ahead!"

Dean kicked off of the rock wall. He was fine for a moment-he started swinging back to the rocks, like he was supposed to. But then, all hell broke lose.

Suddenly, the knot that Dean had tied came undone, and he crashed into the rocks.

"DEAN!" John screamed. Not again!

But Dean was falling. Just as far as Sammy had, with just as much force-and there was no way that John could help him.

Dean was screaming in agony as he crashed into rock after rock. He could taste blood, and the rest of his body was on fire. His last thought was, I'm sorry, Dad.

And then he crashed into the ground, and everything went black.
