“He looks," Simon had once said to Isabelle, "like he's thinking about something deep and meaningful, but if you ask him what it is, he'll punch you in the face.”
“What about Isabelle?" Simon asked. "Where is she?" The humor, such as it was, left Jace's expression. "She won't come out of her room," he said. "She thinks that what happened to Max was her fault. She won't even come to the funeral." "Have you tried talking to her?" "No," Jace said, "we've been punching her repeatedly in the face instead. Why, do you think that won't work?" "Just thought I'd ask." Simon's tone was mild.”
“Simon?" she asked. "I have a stupid question.""What is it?""Did you sleep with Isabelle?"Simon made a choking sound. Clary swiveled slowly around to look at him."Are you okay?" she asked."I think so," he said, recovering his poise with apparent effort. "Are you serious?""Well, you were gone all night.”
“So--what's it like, being a vampire?""Aline!" Isabelle looked appalled. "You can't just go around asking people what's it like to be a vampire!""I don't see why," Aline said. "He hasn't been a vampire that long, has he? So he must still remember what it was like being a person." She turned back to Simon. "Does blood taste like blood to you? Or does it taste like something else now, like orange juice or something? Because I would think the taste of blood would-""It tastes like chicken," Simon said, just to shut her up."Really?" Aline looked astonished."He's making fun of you, Aline," said Sebastain”
“Where's Simon?" Clary interrupted.Isabelle wobbled. "He's a rat," she said darkly.Did he do something to you?" Alec was full of brotherly concern. "Did he touch you? If he tried anything-"No, Alec," Isabelle said irritably. "Not like that. He's a rat."She's drunk," said Jace, beginning to turn away in disgust.I'm not," Isabelle said indignantly. "Well, maybe a little, but that's not the point. The point is, Simon drank one of those blue drinks- I told him not to, but he didn't listen- and he turned into a rat.”
“Really? Are you going to ask him to be your partner?" Isabelle asked. "It's like cotillion, this partners business, except with killing.""So, exactly like a cotillion," said Simon.”
