Stephen had taken his time before the party. He knew that Adrian needed time to settle after he put the collar on. So they stayed at Hogwarts, while he dressed and got ready, while Adrian stayed in a corner, kneeling on a pillow. By the time they arrived at the party, Adrian was calm and into his role.
They had settled on one of the couches. He was talking to Sean who kept glancing over to Adrian, obviously shocked by the change. Stephen had to admit that he was surprised too; he hadn't expected Adrian to do so well, to completely shut out the rest of the world. However, that allowed him to turn his attention to the other guests.
He had to admit that he liked this, liked being able to do something other than check on Adrian the entire time. However there was only so much chit chatting. "Do you want to go downstairs?" he asked Sean. When the other man nodded, Stephen motioned to Adrian, waiting for him to move before standing.
