Justin nodded, "Well, I'm glad you came. It means a lot." He might not have seen Clary for awhile before the art show, but it was nice to know that she would come to support him regardless.
When she bumped his shoulder, he glanced over at her and shrugged, "I don't know. Billy is in New York and I miss him so fucking much and I'm worried." As far as Justin knew, Clary wasn't aware of what was going on with Billy and his dreams and Teddy. He didn't know that Billy had been talking to her this entire time about him and Teddy and how Billy felt about them both.
