“Hey, Clary. You take care of yourself," he said. "I know you can." He paused. "And take care of Jace, that poor, helpless blond."
Jace made an obscene gesture, which actually did feel familiar to Simon, so he knew that was their thing.”

“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."
