“Even if you haven't had the exclusivity conversation, they're still going to be mad if they find out you're dating someone they know and you haven't mentioned it. It's a dating rule." "Well, how am I supposed to know that rule?" "Everyone knows that rule." "I thought you were supposed to be on my side." "I am on your side!”
“Some burns," Clary said. "Nothing that matters""Everything that happens to you matters to me.""Well that certainly explains why you haven't called me back once. And the last time I saw you, you ran away without telling me why. It's like dating a ghost."Jace's mouth quirked up slightly at the side. "Not exactly. Isabelle actually dated a ghost. She could tell you--""No," Clary said. "It was a metaphor. And you know exactly what I mean.”
“OR am I the only warlock you know?""No... but you are the only warlock we know who happens to dating a friend of ours.”
“I am with you. I'm not going anywhere.""Is there anything special you want to see? Paris? Budapest? The Leaning Tower of Pisa?"Only if it falls on Sebastian's head, she thought. "Can we travel to Idris? I mean, I guess, can the apartment travel there?""It can't get past the wards." His hand traced a path down her cheek. "You know,I really missed you.""You mean you haven't been going on romantic dates with Sebastian while you've been away from me?""I tried", Jace said, "but no matter how liquored up you get him , he just won't put out.”
“Don’t you even care where I’m going?” he said. “What if I were going to Hell?”“I’ve always wanted to see Hell,” Cecily said calmly. “Doesn’t everyone?”“Most of us spend our time struggling to stay out of it,” said Will. “I am going to an ifrit den, if you must know, to purchase drugs from violent, dissolute reprobates. They may clap eyes on you and decide to sell you.”“Wouldn’t you stop them?”“I suppose it would depend on how much they would give me.”
“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-”
“You don't get to decide," she said, "where I go, or when.""I know." His voice was ragged. "I've always known that about you. I don't know why I had to fall in love with someone who's more stubborn than I am.”
