And there you stand, opened heart-- opened doors

Full of life with the world that's wanting more

But I can see when the light starts to fade

The day is done and your smile has gone away

She can pretend all she likes, but she can't fool him; he knows her too well. While the rest of the family might find this normal behavior, but Derek knew better. She was trying to act normal like nothing was wrong. She'd kept up her study habits, hung with Emily. She had smiles for everyone. For all the world, it seemed as though Casey was coping, moved on even.

But Derek had seen the side she kept hidden from everyone else. He heard her crying in her room at night, when she thought everyone else was asleep. She would tear up at the slightest reminder of him, and leave the room before anyone would notice. She was quieter now. She didn't fight back when Derek pranked her, in fact she wouldn't react at all. No insults, no attempt at a revenge prank, no splitting his name into two distinct syllables, the way only she could, making Derek's blood run. Her spirit was gone; She wasn't Casey anymore.

Let me raise you up

Let me be your love

Derek would never admit it, but it hurt him to see her so broken, so lifeless. To see his strong, vibrant Casey reduced to tears over him. Where did he get off, anyway, kissing Casey's cousin? Someone who could never measure up to Casey herself? Every time he thought about it, Derek wanted to tear Truman limb from limb. But always, he managed to squash that particular desire; Casey needed him, and he couldn't be there from a jail cell.

It was never anything big, but it was enough to get her to smile. A real smile, not the fake one she gave the rest of the world. Making her favorite tea. Getting her books from the library. Even letting her sit in his chair. At night he would stay with her, and they would just talk. He even tucked her in.

"I thought you didn't do PDA, or feelings in general," Casey had commented one night.

"You're the exception, Space-Case," he'd told her, his trademark smirk on his face.

You're always the exception.

May I hold you

As you fall to sleep

When the world is closing in

And you can't breathe,

May I love you

May I be your shield

When no one can be found

May I lay you down

Derek didn't know when it started. When he started to realize that he loved Casey. Whether the emotion had built up over time or if it had been there from the very beginning, just waiting for him to acknowledge it.

All I want is to keep you safe from the cold

To give you all that your heart needs the most

Love was a new feeling for Derek. The only time he had ever come close to feeling it was with Sally. But with Sally, he just had to be himself, and everything flowed from there. With Casey, everything was different. He found himself studying, trying to improve his grades, laying off the more volatile pranks in his arsenal, throwing the occasional comment his way. Derek found that he was changing. For her. Changing into someone who was worthy of her, someone she wouldn't be ashamed of. Someone Casey could be proud of.

May I hold you

As you fall to sleep

When the world is closing in

And you can't breathe,

May I love you

May I be your shield

When no one can be found

May I lay you down

All that's made me

Is all worth trading

Just to have one moment with you

So I will let go

Of all that I know

Knowing that you're here with me

For your Love is changing me.

"Derek?" Casey said one night.

"Yeah, Case?"

"I just wanted to thank you. You've been really nice lately and I know it won't last-"

"You're welcome Case. Just don't mention it to anyone, it'll ruin my reputation."

Casey laughs, and Derek smirks, fighting off the urge to kiss her. She needs a friend right now, and that's what he would be.

"Good night, Derek."

"Good night, princess."

May I hold you

As you fall to sleep

When the world is closing in

And you can't breathe,

May I love you

May I be your shield

When no one can be found

May I lay you down
