“Clary glanced past him and asked, "Where's Magnus?"
"He said it would be better if he didn't come. Apparently he and the Seelie Queen have some kind of history."
Isabelle raised her eyebrows.
"Not that kind of history," said Alec irritably. "Some kind of feud. Though," he added, half under his breath, "the way he got around before me, I woudn't be surprised.”

“You could dress it up with a sequined headband,” Magnus suggested, offering his boyfriend something blue and sparkly. “Just a thought.”
“Resist the urge, Alec.” Simon was sitting on the edge of a low wall with Maia beside him, though she appeared to be deep in conversation with Aline. “You’ll look like Olivia Newton-John in Xanadu.”
“There are worse things,” Magnus observed.”

“It’s me,” he said, and cleared his throat. “I could understand if you didn’t believe me, but I swear on the Angel, Iz, it’s me.” Alec said nothing, but his grip on Jace’s hand tightened. “You don’t need to swear,” he said, and with his free hand touched the parabatai rune near his collarbone. “I know. I can feel it. I don’t feel like I’m missing a part of me anymore.”
“I felt it too.” Jace took a ragged breath. “Something missing. I felt it, even with Sebastian, but I didn’t know what it was I was missing. But it was you. My parabatai.”

“So it's true what they say about warlocks, then?"
Alec gave him a very unpleasant look. "What's true?"
"Alexander," said Magnus coldly, and Clary met Simon's eyes across the table. Hers were wide, green, and full of an expression that said Uh-oh. "You can't be rude to everyone who talks to me."
Alec made a wide, sweeping gesture. "And why not? Cramping your style, am I? I mean, maybe you were hoping to flirt with werewolf boy here. He's pretty attractive, if you like the messy-haired, broad-shouldered, chiseled-good-looks type."
"Hey, now," said Jordan mildly.
Magnus put his head in his hands.
"Or there are plenty of pretty girls here, since apparently your taste goes both ways, Is there anything you aren't into?"
"Mermaids," said Magnus into his fingers. "They always smell like seaweed."
"It's not funny," Alec said savagely, and kicking back his chair, he got up from the table and stalked off into the crowd.”
