“All right," he said.
Magnus whipped toward him in the dark, all coiled energy now, all cheekbones and shimmering eyes. “Really?”
“Really,” Alec said. He reached out a hand, and interlinked his fingers with Magnus’s. There was a glow being woken in Alec’s chest, where all had been dark. Magnus cupped his long fingers under Alec’s jawline and kissed him, his touch light against Alec’s skin: a slow and gentle kiss, a kiss that promised more later, when they were no longer on a roof and could be seen by anyone walking by.
“So I’m your first ever Shadowhunter, huh?” Alec said when they separated at last.
“You’re my first so many things, Alec Lightwood,” Magnus said.”

“Emma’s gaze went from Alec to Jace, curious. “Do you worry about him?” she asked Alec, surprising a laugh out of him.

“All the time,” he said. “Jace could get himself killed putting his pants on in the morning. Being his parabatai is a full-time job.”

“If you’re not doing okay, you should tell me," Jace said. "We’re all under stress, but we have to keep it together as much as we-"
Alec whirled on him. There was disbelief in his eyes. “Doing okay? How would you be doing?” he demanded. “How would you be doing if it were Clary that Sebastian had taken? If it were her we were going to rescue, not knowing if she was dead or alive? How would you be doing?”
Jace felt as if Alec had slapped him. He also felt as though he deserved it. It took him several tries before he could get out the next words. “I-I would be in pieces.”
Alec got to his feet. He was outlined against the bruise-colored sky, the glow of the broken moons reflecting off the ground; Jace could see every facet of his expression, everything he had been keeping pent up. He thought of the way Alec had killed the faerie knight in the court; cold and quick and merciless. None of that was like Alec. And yet Jace had not paused to think about it, to think what drove that coldness: the hurt, the anger, the fear. “This,” Alec said, gesturing toward himself. “This is me in pieces.”
