Daemon was sitting near to the back of the coronation, dressed in loose yellow robes. He had yet to be born when his uncle was crowned king, and this was actually his first time seeing the Iron Throne in person. He was far more interested in the titanic seat of iron and steel blades than he was in the coronation itself, and he had toned out the High Septons droning some time ago. 

He finally looked around the room, trying to determine who was who in the mass of nobles attending the coronation. The Lannisters were unmistakable of course, and he thought he recognized the Starks near the front as well, but he was unsure about the rest. He was mentally making notes about who could be potential allies in Kings Landing but at the moment he didn't see anyone who he knew might be sympathetic to his cause.

His attention returned to Rickard Arryn and the High Septon when a murmur rumbled through the room and his eyes were drawn to the silver crown the High Septon was about to ceremoniously place atop Rickards head. He concealed his feelings of disgust at the ornate silver crown, viewing it as all but a direct insult to the crowns of the Targaryen kings, but despite his fury he remained outwardly calm, eyes eventually being drawn to the Lannister lord and someone he was conversing with, assuming the other man must be a highborn lord as well, due to his seating location.
