“Magnus, standing by the door, snapped his fingers impatiently. "Move it along, teenagers. The only person who gets to canoodle in my bedroom is my magnificent self."
"Canoodle?" repeated Clary, never having heard the word before.
"Magnificent?" repeated Jace, who was just being nasty. Magnus growled. The growl sounded like "Get out.”

"There's no need to clarify my finger snap. The implication was clear in the snap itself.”

“Malachi scowled. "I don't remember the Clave inviting you into the Glass City, Magnus Bane."
"They didn't," Magnus said. "Your wards are down."
"Really?" the Consul's voice dripped sarcasm. "I hadn't noticed."
Magnus looked concerned. "That's terrible. Someone should have told you." He glanced at Luke. "Tell him the wards are down.”

“Magnus? Magnus Bane?”
“That would be me.” The man blocking the doorway was as tall and thin as a rail, his hair a crown of dense back spikes. Clary guessed from the curse of his sleepy eyes and the gold tone of his evenly tanned skin that he was part Asian. He wore jeans and a black shirt covered with dozens of metal buckles. His eyes were crusted with a raccoon mask of charcoal glitter, his lips painted a dark shade of blue. He raked a ring-laden hand through his spiked hair and regarded them thoughtfully. “Children of the Nephilim,” he said. “Well, well. I don’t recall inviting you. I must have been drunk.”
