Ethan groaned and threw his arm over his eyes. He didn't know what time it was, except that he recognized he'd not gotten near enough sleep. He rolled over in the bed and watched with an appreciative eye as Rupert moved around. Minutes later Rupert was pulling on his robe and leaving to answer the door. And then he could hear Rupert saying Buffy's name.
Oh, bloody hell, Ethan thought to himself. He dragged himself out of bed, and dug around for his trousers, finding them kicked halfway beneath the bed. He pulled them on quickly. After all, he'd prefer not to be naked when faced with the Slayer. It wouldn't do to scandalize the girl, not with their history.
He pulled on one of Rupert's jumpers, which was much too large for either of them, but was very comfortable. It was some time before he stepped outside of the bedroom.
((Posting it this way, so that Giles and Buffy can talk some before Ethan walks in.))
