JK owns the characters, and OneRepublic owns the song.

Hello world hope you're listening
Forgive me if I'm young or speaking out of turn
But there's someone I've been missing
And I think that they could be the better half of me
They're in the wrong place trying to make it right
But I'm tired of justifying

Tonks sat in her apartment in Hogsmead, looking out the window at the full moon. Remus was out there, a werewolf among a pack. Was he okay? Was he bleeding in a ditch somewhere, having faced the wrath of Greyback?
She missed him.

Remus looked up at the moon, half full and turned on the spot.
He didn't know where he was going, just away from the pack.

He ended up in the Shrieking Shack, looking out the window towards Hogsmead, he saw a light on in one of the rooms above Hog's Head. He knew Dora was stationed in Hogsmead, could that be her light in the window? He shook himself and walked away, wishful thinking.
He missed her.

So I say to you come home come home
'cause I've been waiting for ya for so long
And right now there's a war between the vanities
But all I see is you and me
And the fight for you is all I've ever known
So come home

Dumbledore was dead. And now the kids knew why she hadn't been herself.

Tonks definitely didn't feel like herself. Her patronus was different, she couldn't morph, her habits had changed. It seemed like that when Remus left, he took part of her with him.
She had to get out of the castle, and away from him.

I get lost in the beauty of everything I see
The world ain't half as bad as they paint it to be
If all the sons and all the daughters stop to take it in
Well hopefully the hate subsides and the love can begin
It might start now yeah
Or maybe I'm just dreaming out loud

"Tonks?"

"What now Remus?" She asked, looking up at him from her sitting position. After her outburst in the Infirmary, she had run off to the grounds for some privacy.

He found her anyway.

"I, uh, oh I don't know how to start."

"You can start off with walking away," she snapped, and to her horror, her voice broke.

He sat down next to her, "I never meant to..."

"Rip my heart to shreds? Cause me to fall into such a deep depression, I don't think I'll ever get out? Fall in love with me?"

"Stop it Dora! Don't you see this hurt me too?"

"Did it? Doesn't seem like it, Remus. Or is this another one of your excuses?"

He clenched and unclenched his hands into fists, and let out an aggravated sigh. "I'm such an idoit," he muttered.

"Yes you are."

The air around them lost its tension.

But until then come home come home
'cause I've been waiting for ya for so long for so long
And right now there's a war between the vanities
But all I see is you and me
And the fight for you is all I've ever known ever known
So come home

"If I say sorry, will you forgive me?"

Tonks snorted, "It might take a little more than that."

"What if, I promised to tie myself to you forever?"

"Pardon?"

"Dora, what if I asked you to marry me? To be with me forever and ever?"

"I...uh, well um, that might work."

Everything I can't be is everything you should be
And that's why I need you here
Everything I can't be is everything you should be
And that's why I need you here

"I need you, Dora, and I honestly thought that if I left, you could move on. I didn't realize how deep our relationship had become."

"Until you left."

"Until I left. Believe me, I knew I loved you, I didn't know how much though. Why does distance make us wise? I don't know. All I know now is that I need you."

She gasped, and the air suddenly electrified.

So hear this now come home come home
'cause I've been waiting for ya for so long for so long
And right now there's a war between the vanities
But all I see is you and me
And the fight for you is all I've ever known ever known
So come home come home

The second she closed the door, Remus pushed her against the door, kissing her passionately. "I like your choice of flat."

"Eh, I didn't really need anything big, I'm on patrol most of the time anyway, I only come to sleep really."

"Mhmmm, that means the bed isn't made doesn't it?"

"Well...I was thinking that the couch is so much more convenient anyway."

They fell back onto the couch with bursts of breathless laughter.

"Welcome home," she whispered before kissing him again.

Hmm, I thought this turned out pretty well, I'd had it on the back burner for a while, and I thought I'd finish it today. I hope you like it! Its my first songfic, so it might not be up to snuff...but oh well. PLEASE PLEASE review! I keeps me motivated and I update sooner :)

Thanks!
