“"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"”

“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.”

“I am not doing this in front of everyone," Simon announced.
“It’s not spin the bottle, Simon,” said Clary. “It’s just food. Not that you’re food, Alec,” she added when he glared. She held her hands up. “Never mind.”

“It wasn’t sexy," he said.
“It was a little sexy,” Simon said.
He felt much better, having fed, and couldn’t help but poke at Alec a bit.
“It wasn’t,” said Alec.
“I had some feelings,” said Simon.”
"Do feel free to agonize about it on your own time.”

“Alec's trying to get Magnus to take him seriously, but he's never told our parents about Magnus, or even that he likes, you know -" "Warlocks?" Simon said.”

“Simon bristled. She wasn’t his Isabelle, not anymore. He wondered if she ever truly had been. Isabelle didn’t seem like the type of girl to belong to someone. It was one of the things he liked best about her.”

“Clary wondered how many boyfriends she'd turned into rats by accident.

“I told you to wait,” he snapped at Alec.
“Don’t you ever do anything I tell you to?”
“Technically you didn’t actually say anything,”
Clary said. “You just gestured.”
“Gesturing counts,” Jace said. “I gesture
very expressively.”

“Magnus, we’re going down to the lake," he said. "Do you want to come?"
“Why?” Magnus inquired.
Alec shrugged, “Clary says it’s pretty,” he said. “I mean, I’ve seen it before, but there was a huge angel rising out of it, and that was distracting.”

“I don't care," Clary said. "He'd do it for me. Tell me he wouldn't. If I were missing-"
"He'd burn the whole world down till he could dig you out of the ashes. I know," Alec said.”
