Jace + Simon
Jace wasn't sure what to say. He wasn't even really sure why he was upset, or at least as worked up as he was. It was nothing they hadn't discussed already in various incarnations. And Simon hadn't pushed and Jace had thought he was fine, open to a little teasing from his brother-in-law, even. But obviously that wasn't the case, and this was the kind of surprise Jace hated.
So he said nothing as he led the way to the dance floor, one hand trailing behind him with Simon's clasped in it. He said nothing as they found a spot and he stepped close to his boyfriend. He said nothing as he rested his cheek against Simon's and tried his best to relax, despite the music being the complete opposite of a slow dance. Finally, when the pressure in his chest had eased enough that he felt like he could truly breathe again, he said, "I'm sorry."
