“We're not dating," Alec said again."Oh?" Magnus said. "So you're just that friendly with everybody, is that it?”
“Did you think I was helping you out of the goodness of my heart? Or am I just the only warlock you know?” (Magnus)…“No,” he said now, “but you are the only warlock we know who happens to be dating a friend of ours.” (Jace)For a moment everyone stared at him-Alec in sheer horror, Magnus un astonished anger, and Clary and Simon in surprise. It was Alec who spoke first, his voice shaking. “Why would you say something like that?”Jace looked baffled. “Something like what?”“That I‘m dating-that we‘re-its not true,” Alec said, his voice rising and dropping several octaves as he fought to control it.Jace looked at him steadily. “I didn’t say he was dating you,” he said, “but funny that you knew just what I meant, isn’t it?”“We‘re not dating,” Alec said again.“Oh?” Magnus said. “So you‘re just that friendly with everybody, is that it?”-pg.241-”
“Sweet pea?'" Alec said."I was just trying it out."Alec shook his head. "No."Magnus shrugged. "I'll keep at it.”
“Fine." Magnus stood up. "But," he added, pausing by Alec's chair and leaning in close to him, "you are not trivial."Alec flushed. "If you say so," he said."I say so," said Magnus, and he turned to follow Isabelle out of the room.”
“Alec," Magnus said. He put a hand on his boyfriend’s shoulder; Alec was standing still, staring angrily at the floor. "Are you okay?"Alec looked at him. "Who are you again?"Magnus gave a little gasp; he looked — for the first time Simon could remember — actually unnerved. It lasted only a moment, but it was there. "Alexander," he said."Too soon to joke about the happy memory thing, I take it," Alec said.”
“How many other people?" Alec asked. "Roughly."Magnus shook his head. "I can't count, and it doesn't matter. The only thing that matters is how I feel about you.""More than a hundred?" Alec asked. Magnus looked blank. "Two hundred?""I can't believe we're having this conversation now," Magnus said.”
