A/N: This is an idea that hit me when I was rereading the Mortal Instruments Series for a book project (don't you hate it when people laugh at your choice of books?) and I hope you like it.

Disclaimer: I own nothing that has to do with the Mortal Instruments Series, except for Blake, and this specific idea.

Chapter 1

Pandemonium

Outside of the club named Pandemonium, teenagers stood in line to get in. The music could be heard from inside, so loud that people in the cars on the street cringed at the sounds. Every time the door opened or closed, those waiting in line could see bright colored strobe lights and see the fog that came from the dry ice.

"Look, it's foam, see?" Jace watched as the kid tried to get his way in, his costume that of some stupid vampire hunter or something. His hair was dark colored, didn't even shine when one of the stray lights hit it. While his hair was strange, his eyes were stranger with their bright green color. It was unnatural, like grass – or anti-freeze. In the corner of his eye, Jace watched as his friend drooled over the boy.

"You think you could lose any more fluids, Blake?" The dark haired girl jumped at the sound of both his voice and her name. While Jace was handsome with his fair hair, golden eyes, and tanned skin, Blake was dark haired, brown eyed, and pale. How the two had ended up hanging out together, neither of them knew, but they'd been friends ever since they could remember.

"Jeez, Jace, you need to learn to stop protecting me and start looking at other girls besides me." She got this look on her face, the one when she made up something funny. Then she smirked, "Unless you're playing for the wrong team? Then I totally understand, and I really think it's better. I mean, we can talk about shopping and cute little animals, and other boys!" He shook his head and used the music that was coming from inside to drown out the sound of her voice.

She was like a sister to him, and that meant she came along with all of the annoyances too. But, soon enough, they got inside and it was too loud to hear anything, much less the girl beside him.

Humans. Why were they so easily tricked into believing lies? He thought to himself, running a finger along the razor sharp blade that the bouncer had thought was harmless foam. A few suave words, a little glamour on the blade, and I got in without a hitch. Silently, he laughed at himself, although it wouldn't have mattered in there. The music drowned out any sound that could be made.

He doubted even a siren could go off in there and be heard.

As he moved through the crowd, he kept on looking for the most delicious one out of the bunch. That was when his eyes came upon the wonderful yet vicious red head. Her flaming red hair was irritatingly familiar, yet he couldn't recall where from. Her green eyes pulled me in even more, reminding me of the ones I made with the glamour on my eyes. Her skin, although pale, was flawless. In the middle of her chest was a bright red pendant that seemed to pulse. It was definitely real – real and vital. The red head motioned with her eyes for the boy to get closer.

Closer, he could see the flaws. Her skin held freckles on her face, and he could see that her mascara was smeared, most likely from sweat. Her hair was slightly crazed from dancing and moving around in here for a long while, and there was a scar on her inner right ankle. Her strappy heels only partially covered the scar.

She kept on moving backwards, motioning for him to follow her. When they stopped, her back had hit a door that said NO ADMITTANCE on the front, and she smirked for only a moment before she, with a quick motion, twisted the knob and entered the room. He followed not long after, unknowing of the three figures following him.

Jace and Blake sat at the 'bar' – since it was an all ages club, there was no alcohol at the bar – and Jace was trying his hardest not to laugh at Blake. She was still gawking at the dark haired guy with the unnatural eyes and strange costume, and it made Jace want to laugh. He had never seen his friend react like that to a guy. "You might want to think about going over there before you lose enough water to make you go into a coma." Once again, she jumped in surprise, this time wiping the back of her hand across her mouth to make sure he was lying. He laughed as she did it.

Then he went off into his own little world, watching everyone else from the perfect seat. He watched as an Asian couple with multicolored hair made out in the corner, seemingly unnoticed. Many of the people on the dance floor were dancing awkwardly, trying to move like the people in music videos by failing miserably. And then he saw the girl.

From the look of her, she was a year or two younger than himself, but the outfit made her look older. Her hair was a flaming red, when you took away all of the strobe lights and fog, flaming red curls that went down to mid back. They weren't tight set curls, but more like wavy curls that made her look even better than the girls who straightened their hair every single morning when they got up. Her eyes were a striking green, but they were a naturally bright green unlike the boy with the vamp hunter costume. Her skin was pale and she had freckles, and she was beautiful. But her beauty wasn't artificial; she just was.

But when he looked at the vamp kid that she was watching, he felt his hopes deflate like a balloon. What did that girl see in a nerd like that? While the dark hair worked in his favor, his eyes and strange costume worked against him. "Oh, you finally found one you like. Finally! Oh, wait, she's taken already, and the hot guy with the vamp hunter costume. Too bad for us." But her voice made it seem like she wasn't too upset.

Jace had just rolled his eyes and turned to look out at the crowd when he saw the dull glint of some kind of knife in the hand of a dark haired girl that was following the couple – the nerd and the red head. When he turned his head, he found the dull glint once again from too other points in the crowd, from two guys. "Blake, go get the bodyguards, I see knives."

Suddenly, the girl got serious and quickly hurried off towards the front. When Jace got down from his seat a moment later, she hadn't made any progress towards the front.

When the guy followed the girl inside the room, he was too occupied with the girl in front of him to worry about the click of the door behind him. He didn't even notice.

"What's your name?" He purred, and he nearly growled when he saw the smile come to her face. What he didn't know at the moment was that it was a smirk. "Clarissa Wayland. Now, are we going to talk or is it going to be something else entirely?" She quickly moved forward, using her fingers on her left hand to hook the belt on his jeans. But, as she did it, he watched as her long black sleeve was pushed back. On her wrist was something silver with little symbols on them, unable to be read if he weren't what he was, or a Shadow…hunter. "No!" His eyes widened for a moment before he was pushed backwards with a tremendous force and something closed around his wrists.

A moment later, his ankles were bound too, and he saw another girl – this one dressed similarly to the red head, but her hair was as black as ink and her eyes were the color of charcoal. Her skin was flawless, unlike the freckled face of the red head. They both wore pendants that pulsed with the sound of their hearts. At the moment, each had smirks on their faces. "Oh, Isabelle, so lucky that you appeared. I almost lost my virtue to some random stranger. Thank God that you appeared when you did."

The demon hissed and writhed as the gold burned and chafed his skin, the gold that made both of the whips making him harmless at the moment. "Clary, enough, let's just finish him off." The girl let a pout come to her face, but her eyes twinkled with mischief. "But why dear Alec? It's so much fun. And I'm guessing you already know what we are, demon." When she turned back to him, his eyes held nothing but disgust and revolt.

"Damn you Shadowhunter!" It hissed, and the smirk once again graced her face as she put her heel lightly on the side of his knee – easy with how he was laying – and looked him in the eye. "Got you."

When Jace entered the room, he didn't know what to expect. A bloody body on the ground, eyes forever open in fright? Or the three surrounding the two with malice in their eyes? But what he saw was nothing like what he was thinking. Are they crazy? he thought to himself, did she just call him demon?

"Got you." The one he had found was named Clary whispered, hardly loud enough to hear, and put her heel on the side of his knee. A moment later, there was the sound of something piercing skin as her heel went through it. The heel was sharpened to a point like a knife, and it easily made its way through skin and sinews, all the way to the bone.

"What the hell!" Once it escaped Jace's mouth, he knew he had said it too loud. The four had heard him. "Oh great, a mundie! Alec, I told you that you didn't put the runes on correctly." The one named Isabelle turned to the one with ink black hair similar to hers and he blushed slightly before he straightened himself. "None of the other mundies were able to see us out there, so I doubt that it was my fault Isabelle." She crossed her arms across her chest and put a pout on her face.

"Whatever the hell you're talking about, I don't care. But you can't just torture humans like that; it's just barbaric." The red head – Clary – smirked as she approached Jace, looking him over appraisingly. "Yeah, you can't just torture humans like that. Isn't that right Simon?" The one with dark brown hair was smiling at her as he nodded.

"So, how about you get out of here and forget you ever saw anything, because I think that no one will believe you anyway. No one else can see us; well, they can see you. They can't see the five of us, since there's a little bitty glamour over us. So, before the demon finds a way out of the bindings, I suggest you get out of here." This time, she gave him an annoyed look, and Jace had to fight the urge to glare at her.

"There's no such thing as demons." He said reproachfully, trying to mean it with these crazy people but failing. "Oh, so I'm just killing some innocent mundane for no reason at all, with this?" When she pulled it up, he nearly gulped in fright. A girl with a knife – a crazy girl with a knife – wasn't who he wanted to be in front of at the moment.

"I suggest you get out of here before you get one of us killed mundie, and I'd prefer it be you over me so…" she trailed off and let him think about it, and Jace didn't doubt that she would let him get killed instead of her. "So, you leaving or what because I –" She was cut off as she started, unable to finish her sentence as the boy jumped from where he was and pulled her to the ground.

The two were a blur of black and her flaming hair, and Jace caught sight of the blade a few times too. But when he blinked, he found that the demon was on top of her, straddling her as his razor like claws shined with blood. A moment later, though, they were a blur once again, and Jace was staring at the black haired girl in amazement. "You're not going to help her or something?"

The girl bit her lip and shook her head. "It's too dangerous. When Clary gets in a fight, it's all too quick to try and help with the my whip; I have as much a chance of hitting the demon as hitting her, and I don't think I don't want to hurt her." He rolled his eyes as they traveled back to the fight before them.

It all stopped suddenly, with Clary on top of him, her hand on the hilt of the blade that she had shown Jace only moments before. It was where his heart was, but not deep enough to kill him, but it sure was a pain. "Now, this isn't deep enough to kill you but it sure will be if you don't tell me something I would like to know in the next few seconds." The demon hissed and tried to throw her off, but he was pinned.

"Fine, fine! I'll tell you something. I know where Valentine is, I can tell you everyone who works for him. Just get this forsaken blade out of me before–" And this time, the demon was cut off as the blade went in hilt deep. "God forsaken demons, they'll say anything to save their own skins."

There was a gurgle and a hiss before the body started folding in on itself. Within seconds, there was no body, none of the black blood, not a trace that there had even been a body right there in front of them. "Stupid mundie, you could've gotten Clary killed!" The one named Alec said, obviously angered by his actions. He stepped forward a couple of steps before with his hands on the hilt of another blade before Clary put a hand on his shoulder.

"Alec, I'm fine." The voice that she had used all evening had gone to be replaced by a kinder and gentler one obviously reserved for him. They were together, of course they were. Just Jace's luck. Although, he doubted he would even considering going out with her after that episode. They were just crazy, and so was he for believing all of that had happened.

When Jace looked over the red head, he saw that her right arm was severely cut, scratches like that of a cat going from her wrist to her elbow. "Just draw me an iratze and I'll be fine Alec. And quickly, please. This stings like hell." The end was more playful and sarcastic, more like what Jace had heard before. He guessed that she was trying to come over as the one giving the orders instead of the damsel in distress.

Alec took out a long wand like item and put it to Clary's skin, and then it went deeper. Wherever it had been, dark black lines were left like a trail. But, once he was done, it almost seemed to burn as the claw marks started to disappear. "Thanks Alec." He gave her a polite nod, an ugly look to Jace, and then stepped back. "Oh, and I doubt that the guards will take you seriously if you can't produce a body, mundie."

When Jace opened his mouth to reply, he was cut off by the sound of the door opening and Blake's voice. "Jace, you in here?" He turned around to find the dark haired girl staring at him with wide eyes. "Where are they?"

He turned around for only a moment and saw Clary's smirk and a wave before she disappeared along with the other three. "Um, I think it might have been a trick of the light. No one's here." The guards looked at him disapprovingly before they threw them out for troublemaking.

"I can't believe you." Blake said as they tried to hail a cab. "Sorry Blake, I really thought I saw something back there." The girl shook her head as she threw her hand up at a passing cab. It went by without noticing.

"Not that Jace. I don't believe you, let's put it that way. You looked like you saw a freaking ghost back there, not some trick of the light. And it was like you were staring at something as you were telling us it was a trick. There was something there, and you're just not telling me." Jace rolled his eyes, putting his hand out as a cab drove up. It stopped to let them in.

And as Blake told the driver the address, Jace swore that he could see a glimpse of flaming red hair as they drove off.

A/N: Now, those of you who read my other stories, I'm sorry for taking time out of writing Could Have Not Should Have so that I could write this. It just came to me and I had to write it. But I promise that as soon as I can, I'll put up the next chapter of Could Have Not Should Have.
