When he'd first noticed the soft golden light filling the room, he'd thought it was Meja. Jace actually enjoyed spending time with her, despite the fact that a part of him wished there was some way for him to punch Magnus for what he'd put Alec through. What he was still putting his brother through. Granted it wasn't quite the Alec, Jace had grown up with but it was still his brother. No matter what universe his parabatai was from. He looked up when he saw a shadow falling over the piano as whoever it was came closer and his fingers paused for a moment before he kept playing.
He'd never expected it to be Mark standing there but he gave him a small smile as he started playing again. "I didn't realize anybody else was still awake."
