"It's just butterbeer, good Lord!" Killian said with a laugh, spinning around as Adara tried to use him as a human shield. ""Sides, you've known them all long enough, you can't be that surprised they took you seriously." Mavis and Nola, romantics even before Mavis and Killian had started dating, seemed to have taken the union as a reason to engineer more of them. Poor Adara, Killian thought as a twig caught on her clothes. He couldn't imagine living with Mavis and Nola, true -- the one sleepover had been chaotic enough.
"What's wrong with Duncan?" Killian asked, shifting slightly so that he was blocking Adara from the view of passerby. "He's, like, fine, for a Slytherin. One of the better ones, really." Killian was fairly neutral on the subject of Duncan, less neutral on the subject of the other boy's friends, but clearly, Mavis had thought there was something there. Or there was potential for something there. Something, anyway.
Killian didn't actually like Duncan all that much.
"Hard to get?" Killian repeated, wrinkling his nose in return. "That's awful misogynistic of him, isn't it?" He frowned, glancing over his shoulder. Ah, well, everybody knew he was with Mavis, right? "You're explaining this to the girls if they ask," he settled on saying, stepping back so Adara could emerge from her new home in the bushes. "Right. Let's go on a vaguely intimidating walk. Should be easy, right? I'm pretty scary looking." A dry, sarcastic joke, but Killian's expression was warm.
