Severus turned around from where he had been looking out of the window. "Faustus is downstairs trying to find a way to beat Violet in which it isn't obvious that he's cheating in between answering letters from Harry in which I believe the irritating Gryffindor is trying to subvert my son." He arched an eyebrow. "And at night he sleeps in his own bedroom and knows better than to disturb me unless it is absolutely necessary." He'd always included nightmares into the definitaion of absolutely necessary but Faustus' nightmares had tapered off of late.
He walked over to where Draco was sitting and slid a hand into Draco's hair. "Then you were talking about the lack thereof. Which is largely your fault. Faustus does know about us after all. There is little need to keep it a secret from him," he said as he leaned down and kissed Draco.
