“Jace was very pale, with hectic spots like fever on his cheekbones. "But it was Valentine. I saw him. In fact, he had the Sword with him when he came down to the cells and taunted me through the bars. It was like a bad movie, except he didn't actually twirl his mustache.”

“But it was Valentine. I saw him. In fact, he had the Sword with him when he came down to the cells and taunted me through the bars. It was like a bad movie, except he didn't actually twirl his mustache. - Jace Wayland”

“It was like a bad movie except he didn’t actually twirl his mustache.”-Jace to Maryse about Valentine, pg.122-”

“And when Jace was ten years old, Valentine killed him. Michael,I mean.""That sounds like something he would do," said Luke. His tone was neutral, but there was something in his voice that made Clary look at him sideways. Did he not believe her?"Jace saw him die, " she added, as if to bolster her claim."That's awful," said Luke. "Poor messed-up kid.”

“Just take the weapon you hold in your hand and drive it through his heart," Valentine's voice was soft. "One simple motion. Nothing you haven't done before."Jace met his father's stare with a level gaze. "I saw Agramon," he said. "It had your face.""You saw Agramon?" The Soul-Sword glittered as Valentine moved toward his son. "And you lived?""I killed it.""You killed the Demon of Fear, but you won't kill a single vampire, not even at my order?"Jace stood watching Valentine without expression. "He's a vampire, that's true," he said. "But his name is Simon.”

“My father didn't take the sword for me. he took it for him. I doubt he even knew about the trial.""How awfully convenient for you, regardless. And for him. He won't have to worry about you spilling his secrets.""Yeah," Jace said, "he's terrified I'll tell everyone that's he's always really wanted to be a ballerina." The Inquisitor simply stared at him.”

“Actually," Clary said, "I think he stayed because of me."Jace's glaze flicked up to hers with a flash of gold. "Because of you? Hoping for another hot date, was he?"Clary felt herself flush. "No. And our date wasn't hot. In fact, it wasn't even a date. Anyway, that's not the point. When he came into the Hall, he kept trying to get me to go outside with him so we could talk. He wanted something from me. I just don't know what.""Or maybe he just wanted you," Jace said. Seeing Clary's expression, he added, "Not that way. I mean maybe he wanted to bring you to Valentine.”
