“Oh, he's rude to everyone," said Isabelle airily. "It's what makes him so damn sexy.”
“What happened to my clothes?""They were covered in blood and poison. Jace burned them.""Did he?" asked Clary. "Tell me, is he always really rude, or does he save that for mundanes?""Oh, he's rude to everyone," said Isabelle airily. "It's what makes him so damn sexy. That, and he's killed more demons than anyone else his age”
“Who's Magnus?" Max inquired"He's a warlock," said Alec"A sexy, sexy warlock," Isabelle told Max."But warlocks are bad," protested Max"Exactly".”
“Oh, its big enough,” he said patronizingly, “but somehow I was expecting…you know.” He gestured with his hands, indicating something roughly the size of a house cat.“It’s the Mortal Cup, Jace, not the Mortal Toilet Bowl,” said Isabelle.-Jace & Isabelle, pg.349-”
“She warned me about Mr. Herondale, though, said he’d likely be rude to me, and familiar. She said I could be rude right back, that nobody would mind.”“Someone ought to be rude to him. He’s rude enough to everyone else.”
“Isabelle waved a hand. "No need to worry, big brother. Nothing happened. Of course," she added as Alex's shoulders relaxed, "I was totally passed-out drunk, so he could really have done whatever he wanted and I wouldn't have woken up.""Oh, please," said Simon. "All I did was tell you the entire plot of Star Wars.""I don't think I remember that," said Isabelle, taking a cookie from the plate on the table."Oh, yeah? Who was Luke Skywalker's best childhood friend?""Biggs Darklighter," Isabelle said immediately, and then hit the table with the flat of her hand."That is so cheating!”
“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.”
