“Mother." Alec's voice as he interrupted his mother was firm, implacable, and notunkind. "Father. There's something I have to tell you." He smiled at them. "I'm seeing someone."Robert Lightwood looked at his son with some exasperation. "Alec," he said."This is hardly the time.""Yes, it is. This is important. You see, I'm not just seeing anyone." Wordsseemed to be pouring out of Alec in a torrent, while his parents looked on inconfusion. Isabelle and Magnus were staring at him with expressions of nearly identical astonishment. "I'm seeing a Downworlder. In fact, I'm seeing a war—"Magnus's fingers moved, quick as a flash of light, in Alec's direction. There was a faint shimmer in the air around Alec — his eyes rolled up — and he dropped to the floor, felled like a tree.”
“Instead of replying, Alec reached down and took Magnus's hands. Magnus let Alec pull him to his feet, a questioning look in his eyes. Before he could say anything, Alec drew him closer and kissed him. Magnus made a soft, pleased sound, and gripped the back of Alec's shirt, rucking it up, his fingers cool on Alec's spine. Alec leaned into him, pinning Magnus between the table and his own body. Not that Magnus seemed to mind.'Come on,' Alec said against Magnus's ear. 'It's late. Let's go to bed.”
“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.”
“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-”
“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.”
“Where's Magnus?" he said. AS he looked toward the kitchen, Clary saw a bruise on his jaw, below his ear, about the size of a thumbprint. "Alec!" Magnus came skidding into the living room and blew a kiss to his boyfriend across the room. Having discarded his slippers, he was barefoot now. His cat's eyes shone as he looked at Alec.”
