The feast was drawing to a close and Killian couldn't remember which shift he had gotten. The other Gryffindor prefect couldn't remember either (typical, Killian thought), so he was dashing across to the Ravenclaw table. Billie would know, she had a good memory for these things. Too bad she was sitting with Rowen, but Barbie was there too. Ki gave the ballet dancer a little wave. "Hi, Billie," Killian began, slightly breathless, "I forget, was it you two or our two going to get the sleeping bags --"
.. the muggle-born, Morgana save us….
Killian's jaw was still open, but the sounds coming from his throat stopped mid-syllable. He blinked, once, slow, then turned his face away from Billie to his least favorite Ravenclaw. His face was frozen, still in the awkward-but-good-natured expression he had when he went to ask Billie his question. It was in stark contrast to his voice, which was suddenly icy-cold. "Sorry, Reinhardt, I didn't catch that. Did you have something to say to me?"
I said, here comes the muggle-born, said Rowen, a smirk on her lips. Would you prefer I use a different noun?
Something hard in Killian's heart snapped. He glared at her for a moment, then -- "Right. One, it's an adjective. Two, get up." He stepped back from the bench, gesturing to the space in between the tables. "Get the hell up. We're settling this. Now." A pause, and then -- "Hall on the left. Come on."
He didn't particularly care who overheard, but he was not broadcasting his voice. He watched just long enough to confirm that Rowen was indeed getting up before striding away himself, long legs carrying him quickly through and out of the Great Hall.
When he turned the corner, Killian slipped his wand into his hand. "Did you think I'd forgotten, Reinhardt?" His lips were moving without much concern for what he was saying. "Or did you forget when you were running your mouth?" He pointed his wand at her. "Draw your wand. If I win, you're going to shut the hell up. Forever."
