I don't own Percy Jackson or When You're Gone by Avril Lavigne.

I always needed time on my own
I never thought I'd need you there when I cry
And the days fell like years when I'm alone
And the bed where you lie is made up on your side

He'd never needed anyone. He'd never needed the father that had abandoned him, he'd never needed the mother that had died when he was young. At one time he'd needed his sister, but that didn't matter now, because she was gone. Just like everyone else in his life. And he'd never cried. Not for her, not for his father, not for his mother. Crying didn't help. People left, it was part of life.

So why did he feel like there was a hole in his heart when he looked at her side of the bed?

When you walk away
I count the steps that you take
Do you see how much I need you right now

Why did he count every step she took when she left him? Why did he think about her every second of the day? Why did he care so much?

When you're gone
The pieces of my heart are missing you
When you're gone
The face I came to know is missing too
When you're gone
The words I need to hear
To always get me through the day
And make it ok
I miss you

He would lie in bed at night thinking about her. Her face would swim in front of his eyes, her electric blue eyes lit up in a smile. He would hear her voice when he closed his eyes, telling him the things he needed to hear to get through the day. And maybe he was ready to admit that he missed her.

I've never felt this way before
Everything that I do reminds me of you
And the clothes you left, they lie on the floor
And they smell just like you
I love the things that you do

When it rained, he would go into the closet and pull out the t-shirt she'd left behind. Thunderstorms were their special time, when they would go out and sit on the balcony of his fourth floor apartment and watch the lightning. Now he brought the t-shirt and watched the lightning with it. It smelled just like her.

When you walk away
I count the steps that you take
Do you see how much I need you right now

And as the lightning flashed through the darkness and the thunder shook the sky, he would remember the day she left. The way she gave him a kiss on the cheek before whispering that she was sorry in his ear. And sometimes he would scream at the sky, asking if she knew how much he needed her. But the thunder drowned out his voice.

When you're gone
The pieces of my heart are missing you
When you're gone
The face I came to know is missing too
When you're gone
The words I need to hear
To always get me through the day
And make it ok
I miss you

And across the city she was sitting in her best friend's apartment, watching the rain pour down the window, mirroring the tears that streamed down her cheeks. She would see his face, hear his voice, and wonder why she ever left.

We were made for each other
Out here forever
I know we were, yeah
All I ever wanted was for you to know
Everything I'd do, I'd give my heart and soul
I can hardly breathe I need to feel you here with me, yeah

And finally she ran from the apartment, barefoot, to the tree they used to sit under in the park. By the time she got there, she was soaked to the bone and her hair was sticking to her neck. But she sat under the tree and sobbed.

When you're gone
The pieces of my heart are missing you
When you're gone
The face I came to know is missing too
When you're gone
The words I need to hear
To always get me through the day
And make it ok
I miss you

And when he came to the same tree on the same stormy night and found her crying there, he didn't say anything. He just sat down next to her and put his arms around her until she stopped. And when she stopped, she wrapped her arms around his neck and asked if she could come back. And when he nodded and told how much he'd missed her, she almost started crying again.

Because they both knew how much they needed each other.

This was a request from Daughter of Wisdom and Music. I feel like this is much happier than I usually write, and I probably could have made it sadder, but I guess I was in a good mood. If there is a song you'd like me to do, I'd be happy to.
