It wasn't exactly like he could blame Clary for liking Jace. But “I'm hiding my feelings for the guy you thought was your brother so you don't doubt that my feelings for you are genuine” was a little different than “I'm hiding my feelings for the guy I didn't tell you isn't actually my brother and by the way his kiss is the one I desire most.”
Clary has never been any good at putting things back together. When they were in middle school and she accidentally knocked over Simon’s Lego Millennium Falcon, he’d already known to say it was fine repeatedly and usher her out the door instead of accepting her offer to help him rebuild it; if he’d let her try, the wings would have ended up upside down and there suddenly wouldn't have been space for the engine. Her heart is in the right place, usually, but it doesn't often translate to her hands. So when he hears through the shadow world gossip mill that Alec's parabatai rune disappeared briefly, it doesn't take more than one look at Jace’s face to know that she’s been fucking around with the threads of fate again. And, well. She's never been that great at sewing, either.
“Some ground rules, please,” Magnus began. “Simon, I know you're friends with Isabelle, but please stick to defending her character within your own head. Raphael—” he glanced at him— “don't be deliberately provocative. Understood?” Raphael nodded once in acknowledgement while Simon bobbed his head up and down. “Well then,” Magnus said, extending his arms in a grand gesture, glass in one hand, “let us vent.”
There's a graveyard that shakes with a coup d’etat and a voice in his head saying blood is stronger than love, so he waits with the blood and does not look at the horror in their eyes and does not remember, does not let himself think.
Most nights they stay up later than they meant to, laughing. “It's like a slumber party every day,” Simon says, and Jace smirks and says, “I don't know what kind of slumber parties you went to,” and Maia says, “More than you. I thought Shadowhunters weren't allowed to have fun.”
