Even after nearly a full lifetime, Dan still hated elevators. His feet hesitated for a moment too long before stepping forward to join Bev. Once on, he leaned against the hand rail and tried to keep his mind off of it. The hesitance was definitely PTSD from his childhood rather than any present Shine related thing.
"I know because of my Shine," he said softly, looking towards the floor. "I haven't really been out of my room much beside when Richie asked me to join him and Eddie or when Los wanted someone to explore with." So he has been more social than he typically would have been, but it was always at someone's request rather than his own desire.
