"I never had to fake caring about Jace."
She saw something flash in his eyes then, a dark jealousy, and she wasn't even sure who he was jealous of. He put his lips against her cheek, close enough that she felt them move against her skin when he spoke. "You screwed us over," he murmured. His hand was around her left arm like a vise; slowly he began to move it down. "Probably literally screwed Jace over-"
She couldn't help it, she flinched. She felt him inhale sharply. "You did," he said. "You slept with him." He sounded almost betrayed.
"It's none of your business."
He caught at her face, turning her to look at him, fingers digging into her chin. "You can't screw someone into being good. Nicely heartless move, though." His lovely mouth curved into a cold smile. "You know he doesn't remember any of it, right? Did he show you a good time, at least? Because I would have."
She tasted bile in her throat. "You're my brother."
"Those words don't mean anything where we're concerned. We aren't human. Their rules don't apply to us. Stupid laws about what DNA can be mixed with what. Hypocritical, really, considering. We're already experiments. The rulers of ancient Egypt used to marry their siblings, you know. Cleopatra married her brother. Strengthens the bloodline."
She looked at him with loathing. "I knew you were crazy," she said. "But I didn't realize you were absolutely, spectactularly out of your goddamned mind."
"Oh, I don't think there's anything crazy about it. Who do we belong with but each other?"
"Jace," she said. "I belong with Jace."
He made a dismissive noise. "You can have Jace."
"I thought you needed him."
"I do. But not for what you need him for." His hands were suddenly on her waist. "We can share him. I don't care what you do. As long as you know you belong to me."
She raised her hands, meaning to shove him away. "I don't belong to you. I belong to me."
The look in his eyes froze her in place. "I think you know better than that," he said, and brought his mouth down on hers, hard.
For a moment she was back in Idris, standing in front of the burned Fairchild manor, and Sebastian was kissing her, and she felt as if she were falling into darkness, into a tunnel that had no end. At the time she'd thought there was something wrong with her. That she couldn't kiss anyone but Jace. That she was broken.
Now she knew better. Sebastian's mouth moved on hers, as hard and cold as a razor-slice in the dark, and she raised herself up on the tips of her toes, and bit down hard on his lip.
He yelled and spun away from her, his hand to his mouth. She could taste his blood, bitter copper; it dripped down his chin as he stared at her with incredulous eyes. "You-"
She whirled and kicked him, hard, in the stomach, hoping it was still sore from where she'd punched him before. As he doubled up, she shot by him, running for the stairs. She was halfway there when she felt him grab her by the back of her collar. He swung her around as if he were swinging a baseball bat, and flung her at the wall. She hit it hard and sank to her knees, the breath knocked out of her.
Sebastian started toward her, his hands flexing at his sides, his eyes shimmering black like a shark's. He looked terrifying; Clary knew she ought to be frightened, but a cold, glassy detachment had come over her. Time seemed to have slowed. She remembered the fight in the junk shop in Prague, how she had disappeared into her own world where each movement was as precise as the movement of a watch. Sebastian reached down toward her, and she pushed up, off the ground, sweeping her legs sideways, knocking his feet out from under him.
He fell forward, and she rolled out of the way, bouncing to her feet. She didn't bother trying to run this time. Instead she grabbed the porcelain vase off the table and, as Sebastian rose to his feet, swung it at his head. It shattered, spraying water and leaves, and he staggered back, blood blooming against his white-silver hair.
He snarled and sprang at her. It was like being slammed by a wrecking ball. Clary flew backward, smashing through the glass tabletop, and hit the ground in an explosion of shards and agony. She screamed as Sebastian landed on top of her, driving her body down into the shattered glass, his lips drawn back in a snarl. He brought his arm down backhanded and cracked her across the face. Blood blinded her; she choked on the taste of it in her mouth, and its salt stung her eyes. She jerked up her knee, catching him in the stomach, but it was like kicking a wall. He grabbed her hands, forcing them down by her sides.
"Clary, Clary, Clary," he said. He was gasping. At least she'd winded him. Blood ran in a slow trickle from a gash on the side of his head, staining his hair scarlet. "Not bad. You weren't much of a fighter back in Idris."
"Get off me-"
He moved his face close to hers. His tongue darted out. She tried to jerk away but couldn't move fast enough as he licked the blood off the side of her face, and grinned. The grin split his lip, and more blood ran in a trickle down his chin. "You asked me who I belong to," he whispered. "I belong to you. Your blood is my blood, your bones my bones. The first time you saw me, I looked familiar, didn't I? Just like you looked familiar to me."
She gaped at him. "You're out of your mind."
"It's in the Bible," he said. "The Song of Solomon. 'Thou hast ravished my heart, my sister, my spouse; thou hast ravished my heart with one of thine eyes, with one chain of thy neck.'" His fingers brushed her throat, looping into the chain there, the chain that had held the Morgenstern ring. She wondered if he would crush her windpipe. "'I sleep, but my heart waketh: it is the voice of my beloved that knocketh, saying, Open to me, my sister, my love.'" His blood dripped onto her face. She held herself still, her body humming with the effort, as his hand slipped from her throat, along her side, to her waist. His fingers slid inside the waistband of her jeans. His skin was hot, burning; she could feel that he wanted her.
"You don't love me," she said. Her voice was thin; he was crushing the air from her lungs. She remembered what her mother had said, that every emotion Sebastian showed was a pretense. Her thoughts were clear as crystal; she silently thanked the battle euphoria for doing what it had to do and keeping her focused while Sebastian sickened her with his touch.
"And you don't care that I'm your brother," he said. "I know how you felt about Jace, even when you thought he was your brother. You can't lie to me."
"Jace is better than you."
"No one's better than me." He grinned, all white teeth and blood. "'A garden enclosed is my sister,'" he said. "'A spring shut up, a fountain sealed.' But not anymore, right? Jace took care of that." He fumbled at the button on her jeans, and she took advantage of his distraction to seize up a good-size triangular piece of glass from the ground and slam the jagged edge of it into his shoulder.
The glass slid along her fingers, slicing them open. He yelled, jerking back, but more in surprise than pain; the gear protected him. She slashed the glass down harder, this time into his thigh, and when he reared back, she drove her other elbow into his throat. He went sideways, choking, and she rolled, pinning him under her as she yanked the bloody glass free of his leg. She drove the shard down toward the pulsing vein in his neck-and stopped.
