Sirius turned when he heard the door opening, and it was good they'd managed to get all the important things said before Jamie and Remus had come to look for them. "Probably another dancing lesson." Sirius smirked at his brother's question.
He chuckled as Remus and James joined them. "I wasn't aware you were keeping him captive." He grinned at his friend. "I suppose we're lucky you decided to come out on your own, and Reg and I didn't have to go looking for you." He reached out and pulled James to come and sit with him when he was close enough.
