Severus looked up with a small smile when he saw Isadora and Iridia enter. His normal instinct would have been to close the book, so as to give her his full attention, but seeing as the title of this particular book was more than a little embarrassing, he decided not to. Instead, he left the book open in his lap, but he folded his hands together atop the pages.
"Not at all," he answered, with a slight shake of his head. "How are you and Iridia?" He wasn't sure if it was proper to etiquette in her world to ask after the health of one's dæmon, as well, but he thought he would, just in case. If she laughed at him for it, he would know better the next time.
