Jace couldn't help but breath a sigh of relief, as relaxed into his arms. Holding her was everything in that moment. It made her real. Made the fact that she was here, real. Something he hadn't been able to let himself believe until that moment.
He leaned his face into her hand, eyes closing briefly to savor the moment. Before he reached up to entwine their fingers, turning her hand so he could kiss the palm. "I am now that you're here." He replied, a rare genuine smile on his face, as he gazed lovingly into her eyes. Before briefly mirroring Clary's actions, by cupping her face with his hand, and then puling her in to kiss her.
