Stay.

All along it was a fever
A cold sweat hot-headed believer
I threw my hands in the air I said show me something
He said, if you dare come a little closer

Isabelle watched as Simon walked out of Magnus's apartment to go and find Clary. An empty feeling spread over her, making her toes feel numb and her heart heavy. Immediately she scolded herself. Why should she care so much if Simon went over to Clary's? He wasn't going to do anything with her, that ship had long sailed far away into the distance. But Isabelle couldn't shake off the horrible feeling of loss. She was being ridiculous, she would see Simon tomorrow. That was soon enough, wasn't it?

An hour went by and Isabelle still felt restless. She felt sick without him, like she'd caught a fever as soon as he'd walked out of her door. She found herself worrying about him. Had he made it to Clary's alright? Of course he had! He was a freakin' vampire for crying out loud! What was he doing at the moment? Was he missing her as much as she missed him?

Isabelle sat up in astonishment. She missed him. She actually missed the damn blood-sucker even though it had only been an hour since she had last seen him. The obscurity of it all was astounding. Isabelle actually missed him, cared if something should happen to him. She had never felt this way and for the first time in her life Isabelle wondered if she maybe was able to love after all.

Round and around and around and around we go
Ohhh now tell me now tell me now tell me now you know

She'd laughed the first time she'd met Simon. The mundie had turned up at the Institute with a stupidly obvious look of pure awe displayed all over his face. It was as though a miracle was happening right in front of him; though from a mere mundie's point of view stumbling into their world was probably considered something of a miracle. Isabelle smiled as she recalled their first encounter of eachother. She knew she was considered beautiful but the look Simon had given her as he'd walked into the kitchen made her almost believe it. Isabelle giggled as she remembered Jace and Simon's conversation. Jace had offended her cooking and Simon had defended her by saying he was hungry and would like some. Jace, being Jace,had made an inappropriate innuendo that Simon was just saying that because he wanted to sleep with her. The whole thing had been very humorous to her, especially when Simon had turned bright red.

Isabelle's smiled faded. Simon had been special even then. She'd just been too blind to see it. Sure, he had changed, being a vampire had seriously improved his eyesight and he was extremely good looking now. But maybe he always had been. This saddened Isabelle for some reason. Stupid Simon. He had changed everything.

Not really sure how to feel about it
Something in the way you move
Makes me feel like I can't live without you
It takes me all the way
I want you to stay

Isabelle hugged her knees, trying to will herself to sleep. She knew it was all in vain though. She wouldn't sleep until Simon was in her sight again. The whole thing was kind of sad really. Why would she even loose a wink of sleep over him? Yes, she supposed she loved him even though the idea was still a little hard to get her head wrapped around.

It was true though. Isabelle loved everything about Simon. His laugh, the way he smiled the way he moved, carefully as though everyone around him was breakable. She loved the way her name sounded from his lips, his sarcasm and terrible jokes. He made her laugh and living in a world like hers that was pretty rare. She loved Simon, t-shirts and all. Isabelle jolted up in bed and advanced to her cupboard. T-shirt. She had one of Simon's t-shirts. After a minute of digging she found it. Isabelle put it on, loving how it still smelled of him. Maybe this would help her sleep. It's funny how something little can make you feel better. Isabelle sighed and closed her eyes. It was no use though; Simon's face was printed on her eyelids. The emptiness washed over her again. This was hopeless. It was as though Isabelle simply couldn't function without Simon. She hadn't depended on anyone since, well, never. But lying alone in the dark Simonless made her realise just how much of her heart Simon had taken up.

It's not much of a life you're living
It's not just something you take, it's given
Round and around and around and around we go
Ohhh now tell me now tell me now tell me now you know

Not really sure how to feel about it
Something in the way you move
Makes me feel like I can't live without you
It takes me all the way
I want you to stay

Simon had been the one who opened up her heart to start with. The stupid idiot had just come barreling into everyone's lives uninvited and ruined everything. Only he hadn't. He had fixed everything. Isabelle hadn't realised truly what love was, her views of it had come from her Mother's own heartbreak- that you could never trust a man because they will just use you and toss you aside like yesterday's trash. She had lived every word; never getting close to anyone. Then Simon came along. It was so cliché it was painful.

But she was glad he had turned up. She had never really had a definite religion but she thanked God for Simon every day. He was her salvation in every way possible. It was Simon who she had given all her love to, and he hers. Realising this just made her want Simon even more. Next time Isabelle saw him she would tell him this.

Ohhh the reason I hold on
Ohhh cause I need this hole gone
Funny you're the broken one but I'm the only one who needed saving
Cause when you never see the lights it's hard to know which one of us is caving

The emptiness inside of her grew. A massive abyss occupied the place where her heart used to be. It was kind of funny really. Even though Simon was the one who had technically died and become a vampire, Simon who had been rejected by his own Mother, Simon who had been cursed, it was Isabelle who had needed to be saved. He had saved her. She had helped him in her own way too she guessed. It was one of the reasons she loved Simon. He knew when she was caving and with a few words and a hug, made it all better again. It was bizarre. But weren't all relationships?

Not really sure how to feel about it
Something in the way you move
Makes me feel like I can't live without you
It takes me all the way
I want you to stay, stay
I want you to stay, ohhh

Isabelle lay on her bed, her eyes tired and barely open. A door opened from downstairs, its hinges making a high-pitch squeaking noise. Isabelle's heart started to beat. Simon. Soft footsteps could be heard from outside her door. The door slowly opened and Simon stepped inside.

"Izzy?" he whispered, climbing into bed next to her. Isabelle smiled, relieved he was here. She turned to face him, admiring the way his curls glowed in the faint light of the room. He smiled down at her and wrapped his arms around her waist.

"Simon." The words were out of her mouth before she could stop them. She blushed faintly at how stupid she sounded.

"What's up Izzy? What do you want?"

Isabelle looked up at Simon, his worried face arousing her emotions. She answered him.

"Stay."

Simon bent down to kiss her forehead. "Always."

Author's Note: Hey guys. This was just a random fic I felt like writing so viola! I love this song and it reminded me, as many things do, of Isabelle. Enjoy and please review!
