"How can you not even give me a steele?" Clary's voice echoed back at her from the high ceilings of Valentine's office. "Is it because you think I will use it against you?"

Her father's dark eyes snapped up to meet her own, angry though his voice was placid. "Because I know you will." Then, looking back at his papers, he let slip a wicked smile. "Besides, you have your brother for protection. What need do you have for weaponry?"

Clary's eyes slid to the bastard in question, lounging across the study. He'd been lost in a book, dark leather boots propped up on the coffee table in front of him. Realizing he'd been mentioned, his black eyes slid from the pages, to Clary, and then to their father, curious. She gave a humorless laugh.

"And that is probably the biggest reason I'm asking for armaments. That demon is more likely to throw me to his brothers then protect me."

"The answer is no, Clarissa."

"He'd probably lead me into danger just so he could watch!"

The cold smile on the demon's face was confirmation. Valentine, however, had clearly had enough. His hands slapped down onto the desk, echoing the sound throughout the study. His gaze snapped up to Clary, narrowing slightly. He might be her father, but that didn't mean she was safe from him.

"Jonathan, please show your sister to her room."

She opened her mouth the protest, but the demon was already up and moving toward her, faster than anyone should be able to move. His smile would have made the devil proud. Not bothering to be gentle, he grabbed her upper arm and began to drag her into the hall. She struggled of course, not that it mattered. Jonathan was so frighteningly strong, all he had to do was tighten his grip and she was wincing from the pain of it.

It didn't take long for him to march her up the manor stairs and down the hall of bedrooms. Once at her door, he shoved her inside and followed at a casual pace, locking the door behind him. Clary stumbled back against the post of her large bed and watched him as he moved slowly to her bookshelf. His slender fingers ran across the line of covers, pausing on one of her drawing books.

"Alright, little doggy, you've done your job." Clary swallowed, fighting to keep herself calm. "Get out of my room."

He let his head tilt back, eyeing her from the side and dropped his hand from the shelf. "I think we should talk."

"I have nothing to say to you." She frowned, watching him turn around to face her. It really was amazing how much he looked like Valentine. Tall and slender, but muscular from a lifetime of training and battle. He had a striking face, elegant almost, and pale. It was the eyes though that always got her. Black, soulless, and empty. They were the only warning that he was not what he seemed. The rest was all attractive and inviting. She supposed it was fitting. The devil had been God's most beautiful angel once.

"You don't seem to like me much, little sister." He said this with a slightest hint of humor, while Clary felt the slow boiling of anger at his title for her.

"You've given me little reason to," she replied tightly. Jonathan moved very slowly around her, like a wolf stalking its prey. His obsidian eyes were on everything else in the room, but she knew that he could strike in seconds, like a snake, should she anger him.

"Ah, this again." He shook his head and paused at her easel. She grit her teeth when his fingers lifted to stroke the half-formed line of a boy, rising from a battlefield. "He is always at the root of things isn't he?"

He meant Jace, she knew.

"Does it hurt to know he was murdered? That he choked on blood and your name when I drove my dagger into his heart."

"Stop." Clary said very softly, hardly able to breathe now that Jonathan was so close.

"It's pathetic really. What little time you had together was spent in shame and regret. Does it hurt to know you could have had your angel all along?"

"Stop it, Jonathan." She spoke now with an exhaustion that reached to her very bones. The demon, however only smiled, glancing down at the signet ring that hung from its silver chain around her neck. The one Jace had given her before running off to play hero. How she hated him for that now.

"Very well, little sister. Shall I pretend for you then? Shall we imagine I am your lost Jace?"

The fury that swelled up in her as that thing spoke his name made Clary's head light with fury. Her fists tightened in the sheets beside her and she grit her teeth, speaking through them.

"You disgust me." She spat, taking cruel satisfaction when his smile melted to cold irritation. He did not like hearing such things, which is precisely why she said them.

"I heard about the way you convinced the Clave to join your cause," he said, leaning against the post of her bed and gazing down at her. His smile was dark. Dangerous. "You showed them the one they loved most. Appealed to their hearts." He rolled his eyes. "It was smart, I'll give you that, but a dirty trick."

"I needed them to realize what they were fighting for." She protested. Jonathan arched a brow, skepticism written across his face.

"You needed them to fight, period, and that was the easiest way to get it. I respect that, though it was a waste of time. Doing what you must, no matter how cruel."

"It wasn't cruel, I…" He was smiling at her again and the look made her nervous. She watched silently as he pulled a steele from his belt and pushed up his sleeve.

"What are you doing?"

"Malachi showed me the mark." He replied, slowly tracing the lines of a rune on the inside of his wrist. "It makes me wonder what else you can create. I can think of a thousand suggestions, but I'm sure we'll explore that soon enough."

Clary's eyes skipped from his face to the mark slowly forming on his skin. She recognized it too late as the mark she'd created to rally the Clave. It would make him into the person she loved most. Instantly her heart began to pound and she turned her face away.

Jonathan chuckled to himself and moved down onto the bed with his knee. Clary squeezed her eyes closed, telling herself to breathe. He was cruel, terrible. God, of all the things he could do to her, of all the torments. Of course he chose this. He knew it was the one thing that could still tear her to pieces.

"Look at me, Clary."

She shook her head, crawling backwards until she hit the headboard, and even that was not far enough away.

His voice! Oh, sweet angels, his voice!

A soft, animal sound of misery escaped her lips as she felt him crawling toward her over the mattress. He straddled her knees, fingers slipping around her chin to force her head straight again.

"Don't be ridiculous Clarissa," he sighed. "Open your eyes and look at me."

"Why are you doing this?" She cried, keeping her eyes tightly closed. His grip on her jaw was growing tighter as he lost his patience with her.

"I'm helping you," he insisted, but she could hear the smile in his voice. "Do you not wish everyday for him to return unharmed. I have heard you weeping here in this room, Clary. Calling out his name."

She slumped forward against him, burying her face against his throat. It was a mistake though because the moment she did she was filled with the scent of earth and sunlight. Of Jace.

"Please stop." She murmured, but Jonathan only chuckled, lifting her up again.

"Then look at me," he murmured. "Think about it, Clary. Who will hold you now that the angel-boy is rotting in the ground? Without this, without me, you are alone."

She shook her head, but the truth was there. How cruel that even the monster could see it. She had it, that one thing every girl dreams of. The things she's taught to hope for from childhood. She'd found love. Real, painful, infuriating, all-consuming, wonderful love. Now she had nothing but her fanatical father and his twisted, heartless son. So, knowing that it would break her heart, she opened her eyes and looked up at him.

Sweet god, he was beautiful. She had almost forgotten. Sure, his face was always in her head, but recently it had come to her in flashes. Golden eyes. A wicked smile. Tousled, blond hair as it caught the sunlight. Though she tried to hold them, the images seemed to slip further and further away, and soon she feared she would forget his face altogether. Yet now it all became a single, breathtaking image. Her fingers trembled as they reached tentatively out to brush the line of his jaw. It was Jace, down to the last scar. Every detail perfect, even his smell.

Jace covered her fingers with his own and smiled down at her. It was hard to breathe, hard to think. This was Jace, her beautiful, strong Jace, alive.

Suddenly, he was pulling her closer to the center of the bed and wrapping his arm around her back. Clary let him, unable to speak as he traced the line of her lower lip with the calloused tip of his finger. How she'd missed those hands, elegant and tapered, like a pianist. She drew a shuttering gasp as he dipped forward and brushed his lips over hers.

Her mind knew this was a lie, even if her body screamed differently. There was something about the kiss, something wrong. She knew this was not her Jace, but it had been so long since he'd held her. For just a moment, she could live with the lie.

Clary's fingers went to the back of his neck, the other hand to his chest. He smiled again in that dazzling way that made her heart ache, breathing her name against her lips. She blinked away tears as they slowly laid down onto the mattress. Jace trailed his long slender fingers down her side, then slipped them beneath her shirt.

"Do you love me, Clary?" He asked it into her throat, kissing a trail downward.

"More than anything," she replied, closing her eyes. The hollow pit in her chest was growing. Demanding that she face reality. Jace was dead, Simon imprisoned for Valentine's experiments, and the Lightwood children had vanished after the last battle. She was alone, and this would not change. Looking back up at him, she silently screamed that it wasn't true. Her world was right here, braced above her. Unbuttoning her shirt.

"Do you want me, Clary?" he asked, gazing steadily down at her exposed self, pale and too thin after so long living with neglect.

"Always," she murmured.

"Prove it," he grinned, "Show me."

Without a word, Clary took his hand and placed it over her breast. He made a soft sound at the back of his throat when she led it south.

"Jonathan!" The cry came from the hallway outside her room.

The air around Jace seemed to ripple and warp like waves of heat, and the glamour melted away, her heart sinking with it. All that was left now was a monster. Jonathan glanced back over his shoulder at the door, cursing under his breath.

"Valentine requests your presence at the Hall of Records. You can deal with the traitor bitch later."

The demon sighed, looking down at Clary as if in regret, then rolled off of her and the bed.

"Yes," he said softly, "Yes I can."

He left her then in quiet sobs, unable to move. Clary was broken and lost.

Hello all. for the moment, this is just a one shot, but if anyone thinks I should continue it, I have a few ideas for the plot.

When I read the books, I knew from the beginning that Jace would end up NOT Clary's brother. (That's just how things work out in books with happy endings) so, I was waiting patiently for the realJonathan Morgenstern to show up and when he did...-deep breath-

Right from the start, "Sebasian" was fascinating. At least for me. Then after the whole Demon-blood thing was brought to light I was completely hooked.

His character is tragic in a way, ruined for his fathers ambition and spurned by his mother for what Valentine made him. It's sad, but I think he might have been one of my favorite characters. I was disappointed that there was so little interaction between Clary and her REAL brother.

It was very obvious that Jonathan envied Jace's relationship with Valentine, being that he was the son his father wanted, and yet the affection went all to Jace. I see him now as wanting to claim what was Jace's, which extends to Clary.

Seeing as he kissed her (which only proves my "wants what's Jace's" theory) I don't think it's a stretch that he would take it further. He IS a soulless, demon bastard.

But that's kinda why I love him. :3
