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

She saw Valentine's eyes as the sword hurtled toward her; it seemed like eons, though it could only have been a split second. She saw that he could stop the blow if he wanted. Saw that he knew it might well strike her if he didn't. Saw that he was going to do it anyway.

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

Why can't I go to Idris with you, then? Because it's not safe for you there O and it's safe for me here? I've been nearly killed almost a dozen times in the past month. That's because Valentine has been concentrating on the two Mortal Instruments that were here. He's going to shift his focus to Idris now. We all know it-- We're hardly as certain of anything as all that. And the Clave wants to meet Clarissa. You know that, Jace. The Clave can screw itself.
