Disclaimer- Just looked in the mirror, and I'm not Cassandra Clare, which means I don't own Mortal Instruments!

Clary's head was spinning. It had all happened too fast. One minute she was sitting talking to the High Warlock Caelan Solstice, though it had involved more yelling than talking, and the next her boyfriend, or should that be ex-boyfriend, was holding her at knife point. Too stunned to speak, Clary could only gasp. Too many thoughts were whizzing through her mind, too quickly for her to process or make sense of them all: why was Jace here? Why did he have a Seraph blade? How did he know where she was? Did he find out what had happened with Simon?

"J…" Clary stuttered, still unable to speak, her eyes frozen in fear of the almost unrecognizable blonde standing before her. The golden eyes that all day shone with kindness now flickered with flames of anger. The hatred in his eyes, it almost reminded her of the old Jace, though that look she had only seen in his eyes when…In fact, she had never seen him like that, not even when he was face to face with Valentine. If he had ever looked that angry, she hadn't been there to witness it.

"Don't speak, Fray," Jace spat, making to effort to hide the malice in his voice. The shining blade was so up in her face it was nearly blinding her so she looked away, but that put her at more risk of an injury so she had no choice but to look at her attacker or the weapon of choice. "I know what you did."

"What?" Clary uttered, for she had nothing else to say. There was nothing she could say, as she was worried that one false move and Jace would kill her. Or maybe that was a bit too extreme; he wouldn't go so far as to kill her, would he? Jace wouldn't even kill Valentine. Then again, that was the old Jace, and this Jace she hardly knew at all.

"I know exactly what you did. The real reason why you broke up with me."

"What? What reason?" Clary tried to play dumb in hope that he'd believe that there was no other motive than the ones she gave him.

"Simon told me everything," Jace sneered. Simon? That explained a lot. But why? Why would Simon tell Jace the truth? Jace must have noticed the horrified look on her face when he added "oh yes, bet you didn't think I'd find out?"

Clary gulped. "I don't know what you're talking about."

"Don't play dumb, Fray. I know why you did it."

"Why then? If you're so all-knowing."

"You sold me out for a piece of gossip," Jace spat. "Someone offered you information in exchange for a date with you. And you, being you, accepted, you broke up with me for a piece of gossip, like some bit of info was more important than your boyfriend. The man who loves you more than anything else in the world." The way he said it, Clary couldn't help but feel guilty.

"Please," Clary panted, "I can explain."

"Go ahead," Jace scoffed, but he released the sword from her throat so she could breathe. She pressed her finger against the spot where the point of the blade was, luckily there was no damage done.

Clary tried to explain how Simon had made her break up with Jace in exchange for the high warlock's address, but she left out the story of why she needed it. Unfortunately, Jace didn't believe her.

"Why did you need his address? Why was he more important than I?" Jace snapped, giving Caelan a look of disgust. Clary had forgotten he was there, he had been that quiet. The dark-eyed warlock sat on the purple bean bag on the other side of the room, he'd moved to shut the door after Jace, and was watching her intensely with extreme curiosity, not with fear or concern, which showed how much he cared. He looked at her like he was anticipating her next move, whether she would retort, tell the truth or escape. It was almost like he was testing her, to see whether she truly was 'grateful'. Though she wasn't sure how nearly getting killed helped anything.

"You wouldn't believe me if I told you," Clary admitted sadly, but it was true.

"Maybe I would," Clary could have sworn his tone was softer then.

Clary took a deep breath in, closed then reopened her eyes and then she—

Screamed.

Standing in the doorway was none other than Simon Lewis.

"Simon?" Clary exclaimed, half-surprised, half afraid. He was grinning a shark-like grin that made his fangs seem more prominent and visible, more menacing. His alabaster skin stood out against the dark walls, his eyes as black as night. The only thing ruining the image the complete vampire image was the leather jacket and baggy jeans he was wearing. Underneath his jacket was not a t-shirt with a witty slogan, but a sports-brand t-shirt. Simon had hated sports, obviously he didn't now.

"Clary," Simon said firmly. "What a pleasant surprise."

"Shouldn't that be what I should be saying to you? Seeing as you weren't supposed to be here." Clary snapped, trying to hide her anger, but to no avail.

"Oh that's right," Simon mused, "you're here to see the High Warlock aren't you?"

"Yes, the one you gave me the address for."

"Wait, you gave her the address?" Jace spoke up, with a hint of annoyance in his tone. "I thought you said it was a Downworlder?"

"And what are vampires?" Simon smirked. "Yes, it was me. I set Clary up, made her break up with you in order for a meagre piece of information she could've gotten from anybody."

"Clary," Jace breathed, looking towards the redhead. "Tell me he's lying."

Clary hesitated, but then decided that it was better to hurt Jace with a truth than to protect him with a lie. She owed him an explanation.

"No, Jace, he's not. He's telling the truth," Clary whispered softly, as if she were breaking the news of a death to someone. Though to her, telling him this was like that.

"What?" Jace blurted. "How could you do that? I don't believe you!"

"You had no trouble believing me before," Clary pointed out, though she didn't think it would help the situation.

"That's because Simon told me, and not you. I knew Simon was capable of deceit, but not you. When Simon told me, I knew there was a chance he could be wrong, so I came here just to check. But now coming here and finding you in the company of this, Downworlder," Jace gestured to Caelan, who was leaning back in his beanbag, amused at the argument, like he'd planned it himself, and he probably had, "I knew he was telling the truth, however ironic it is!"

Simon nodded smugly. "It's awful, isn't it, Jace?"

"Don't try to be sympathetic, vampire," Jace spat 'vampire' as if it were the filthiest word he knew. "If it wasn't for you then none of this would have happened."

"If it wasn't for me?" Simon repeated furiously. "If it wasn't for you being such a pathetic, spineless little prissy then maybe Clary would have liked you more and would have stuck with you!"

The expression on Jace's face morphed from disgust to extreme rage. Clary found it hard to believe how quickly his mood had changed. He'd entered the room angered, then to disbelieving, to disheartened, to annoyed then to fury.

"At least I'm not a filthy freak of nature," Jace retorted. Clary didn't want to know where this argument, though it seemed to be dwindling into an insulting match, would end. A fist fight? If Simon were an ordinary vampire, it would have been a tough call to decide the winner. But Simon was not an ordinary vampire; the Mark of Cain lay upon his white forehead, cleverly concealed by a sweeping fringe of dark brown locks of hair. Jace wouldn't be able to lay a finger on him without exploding into dust, for whoever tried to slay Cain would have vengeance taken upon them sevenfold.

"I'm the freak of nature? Then what are you? At least I embrace my nature, unlike you, who cowers at even the mention of a demon."

"Not true!" Jace shouted immaturely, and then caught himself. "But unlike you, my nature doesn't include sucking the blood from innocent flesh."

"How is that any better than you? You kill demons. In fact, how is that any better than mundanes who feast on the flesh of murdered animals? Before I was a vampire I was a vegetarian you know, but now I have no choice but to feed on blood. And, I didn't have a choice in it, it was you lot who got me Turned, remember?"

A pang of guilt struck Clary like a bullet. She remembered Simon being adamant about becoming a vegetarian when he was ten, despite his mum's warnings about protein deficiency and other problems. Ever the stubborn one, Simon protested that vegetarian diets, if eaten well, were in fact healthier than meat diets, and he could eat vegetarian diets. His mother gave in, and he was so happy afterwards. Now he wasn't technically eating meat, but still, feeding on their blood counted. Simon must have had daily battles with his conscience for ages afterwards. Clary hadn't even considered that. Still, it was better than the alternative, which was starving. And having him Turned was a much better alternative to dying, which would have happened if she allowed it, which she would never have done. She even put the Mark on his head to prevent him from dying.

"It saved your life!" Jace protested, as if he could read her mind. "If you didn't, you'd be dead."

"In case you haven't noticed," Simon chuckled, "I am dead. So bang goes your logic, angel boy."

"Angel boy, ooh, I'm so scared!" Jace sneered.

"You should be," Simon hissed, baring his fangs and twisting his face into a growl. He wasn't going to bite him was he?

"Bring it on, rat boy!" Jace countered, holding out his gleaming Seraph blade, the shining almost blinding Clary.

"Both of you, STOP!" Clary yelled, jumping in between them with both of her hands up, hoping they'd stop and listen and not go in the for the kill while she was between them. "Listen to yourselves! You're fighting each other for nothing. It's me who's in the wrong, not you two. It's me who you should be arguing and fighting with. Besides, Jace, there's no way you could beat Simon."

Simon smiled, "No offence, but Jace couldn't beat anyone."

"I mean, because you've got the Mark," Clary said impatiently, no longer caring that the dark-haired warlock was observing them. "Nothing to do with Jace's physical strength, which would be far greater than yours if you weren't a vampire."

Simon rolled his eyes, but said nothing.

"Look, Jace, I'm sorry, but I had to do this, and I wish I could tell you why, but I can't. Simon, I'm sorry for leading you on, I only agreed to date you because I thought if I got to the warlock everything would be set back to normal, and that meant not dating you," Clary winced.

"What do you mean, back to normal?" Jace questioned.

"Is it okay if I tell them?" Clary asked the warlock, who was fiddling with a strand of charcoal hair. He looked up at her with wide eyes and said "hmm?"

"Can I tell them the truth?"

"Clary, you aren't seeing this guy are you?" Jace demanded.

"No," Clary shook her head, then turned back to face Caelan. "Can I?"

Caelan sighed. "That's up to you; I can't make all of your decisions for you. It won't alter the spell in any way, shape or form, but it would make a difference in me judging your character."

"What do you mean?"

"Again, I can't tell you everything that would make it harder for you to make your own decisions and then you wouldn't be acting like your true self, and then the spell would never be reversed."

"What spell?" Jace and Simon asked.

Clary looked at them, then back at the warlock and knew exactly what to do.

Woohoo! I updated within a week! Unfortunately I won't be able to update until at least Monday because I'm very busy this weekend. One of my plans is my best friend's (she's called StrifeMe on here, check her out!) birthday party, which is cosplay themed and I'm going as Isabelle!
