Because this is it. This is the chapter where it happens.

*dramatic music*

Sam ran through the hallways of the palace, pushing doors open and ducking down corridors until he found the door he'd been looking for. Narrow, dusty, and wooden, it led to the lake behind the castle and the mountains beyond.

"Sammy, wait!"

Dean couldn't catch him. No one could. He'd hurt them. He couldn't do that to Dean. Not again. If he left, Dean could have the life he wanted with Lilith. He ran down the steep stone steps to the enormous lake.

How am I going to get across this?

Sam thought back to the lonely hours in his room. Once Dean had started going outside to work with Bobby, he'd been able to sneak into the library and collect books. He'd done hours of research on the element of fire, of curses and magic, trying to find a way that he could fix himself, but he found nothing. However, in his days of carefully turning pages, trying to avoid turning the delicate paper to ashes, he had learned about the elements of fire he did control. Not only could he make flames, he could evaporate water. He'd never tried with something this big, but maybe he could make it shallow enough to cross. Carefully, he placed his foot on the surface of the lake. He expected a hissing, perhaps steam, but instead, shiny black stone spread from where he had touched the surface. It looked familiar.

Obsidian. Volcanic rock.

Well, it made sense. He'd seen it on one of the books he'd read, but hadn't paid it much thought. He wanted to fix the curse, not make it stronger.

Sam carefully placed his foot on the rock patch. It held. Concentrating, he ran, creating stepping stones. He didn't see how the obsidian kept spreading

"Sam!"

He didn't look back. Even if he wanted to.

It was quiet in the forest. The kind of quiet where you could think as much as you wanted to. And Sam did think. He thought about the hours alone in the castle. He thought about the blame in his father's eyes that never really went away. He thought about the sound Dean's voice made through his door, and how hard it was to not open it. He thought about how he lived in fear of losing control, of forgetting that he was a monster and he'd hurt anything he touched.

Sam realized he was near the top of the North mountain. He'd probably been walking for hours, but he hadn't noticed. It was probably past midnight. He dully noted that the trees behind him were glowing with fire. The normally snowcapped mountain was simply bare rock. And there was only one reason that it was like that.

A trail of destruction.

Sam smirked.

That sounds about right.

The fire was kind of…beautiful. In a strange way. For the first time in a long time, Sam thought about the days he spent with Dean before the accident. Dean would always watch Sam's fire displays with awe and amazement. Back then, Sam never thought he was a freak.

He stared up at the stars

The flames glow bright on the mountain tonight
Not a snowflake to be seen
A kingdom of isolation,
And it looks like I'm the king

With a dawning realization, Sam realized that he wasn't just angry at himself. He was angry at his father for blaming him for something that wasn't his fault. And he was hurt. Hurt that he was forced to shut himself away from his family and life. He was tired of observing life through his window.

The fire is burning like this swirling storm inside
Couldn't keep it in, heaven knows I tried

He had tried. Ever since he was little, he'd tried to lock it away. But he couldn't. Not anymore. Maybe his father was wrong.

If he tried hard enough, he could come back to his family. If he tried hard enough to conceal it, to shut it away, maybe he'd be fixed. Like his father wanted.

"Can't you control it, Sam?"

"Conceal it, don't feel it. Don't let it show."

"Can't you fix him?"

"Oh, Samuel. What have you done?"

Don't let them in, don't let them see
Be the good boy you always have to be
Conceal, don't feel, don't let them know

Sam looked at the single glove on his hand. He hated the gloves. They reminded him of what he had done. With the gloves, he could never be anything but a freak.

No one was here for him to hurt. He didn't need to wear them here.

He pulled off the glove, throwing it into the sky, letting the wind blow it away.

Well, now they know…

Sam carefully waved his hand, creating a flickering flame, and then another.

Let it go

Let it go

He thought about his brother and him working together to rescue Kevin, the AP student. Slowly, he concentrated, drawing his hands up and creating a blaze. It only lasted for a few moments, but it was blindingly bright. For a moment, Sam saw something in the fire, but it didn't last long enough for him to properly make out what it was.

Can't hold it back anymore

Sam felt his fear lessening now, and it was showing. His flames were larger, brighter.

Let it go, let it go
Turn away and slam the door

He wasn't evil. The fact that he could create fire didn't make him evil, any more than his long hair or tallness did. It was who he was.

I don't care
What they're going to say
Let the fire burn on,

Sam shrugged off his jacket, leaving it behind on the ground, smiling faintly

The heat never bothered me anyway

He ran now, not out of fear, but out of joy. He hadn't felt this free since he was a little kid.

It's funny how some distance
Makes everything seem small
And the fears that once controlled me
Can't get to me at all

It hit him that he could do whatever he wanted on the mountain. No one else was here, so he couldn't hurt them.

It's time to see what I can do

Sam almost tripped, glancing down. There was a ravine between him and the top of the mountain. He concentrated, thinking staircase. Maybe this would work. He wanted to see the view from the mountain peaks, the fire of the sunrise. He pushed outward, the image of stairs in his mind.

To test the limits and break through

A stairway, grander than the one in the castle foyer, appeared in front of him. It appeared to be made out of glowing coals.

No right, no wrong, no rules for me

Sam carefully put his foot on the first staircase, and watched delightedly as the coal swirled away, revealing flawless obsidian underneath.

I'm free

Sam ran up the stairs, which grew as he moved, swirling in clouds of black, gold, red, orange and blue.

Let it go, let it go
Like a phoenix, I will fly

He leapt off the stairs, laughing in pure joy

Let it go, let it go
You'll never see me cry

He was speaking to his father, to his brother, to everyone.

Here I stand

Sam slammed his foot down, creating an enormous crystal-shaped patch of obsidian that spread from where he stood

And here I'll stay
Let the fire burn on

It wasn't an accident completely. Maybe he'd always known he could do this. Maybe it was always there. Just waiting for him to acknowledge it. To stop pushing it away. But when Sam brought his hands upward, he knew exactly what he was going to do.

The castle grew around him, pure black, glittering glass, glowing embers. Flawless, beautiful, perfect. Sam's arms fluttered around him, creating walls, windows, arched doorways.

My power flares through the air into the ground
My soul is spiraling in sparkling embers all around
I won't be devoured by the inferno or the blast

I'm never going back,
The past is in the past

Sam ran his hands through his hair, streaking it with colors of his fire, ruffling the locks he'd worked on flattening for hours.

Let it go, let it go
And I'll rise like the break of dawn
Let it go, let it go
That perfect boy is gone

An idea occurred to him. Sam waved a hand over his plaid shirt and dress pants. In a cloud of sparks, they vanished and were replaced by a pure white tailored suit that fit him like a glove.

Sam glided across the floor to the balcony, with a sweeping view of the sunrise that reflected the castle he had made. He wasn't the disgraced prince anymore. He wasn't the freak. He was someone new. His own person.

Here I stand
In the light of day
Let the fire burn on,
The heat never bothered me anyway

A/N

Okay, so the white suit is because our favorite supernatural moose looked fabulous in it and we didn't see enough of him in it. Not because he's evil. Because he's not. I hope you like this. I worked really hard on it. I wanted to do it justice.

Enjoy. I love you guys.

If you could review that would be great.
