Misha/Bella
Misha had been standing at the snacks table, doing a bang up job of ignoring the students who tried to spike the punch. It was only once he had seen the third mickey of hard liquor go into the same punch bowl that he stepped in and suggested the fifth year Ravenclaw put the bottle away. After all, school dances were always more fun with a buzz, but no one liked a sloppy drunk.
At least his assignment was something to distract him away from fuming about his little sister's costume. Misha had assured his mother before he left for the year that he would keep an eye on her "without smothering her". He knew what she meant, stand back and let Marina live her own life but be ready to step in if there was a threat of real harm. Misha knew her current state of dress was nothing unusual for the dance, not with Enjolras dressed as some kind of French prostitute, and Misha himself in a very revealing Dionysus costume. It still drove him up the wall though and he had to force himself not to stare at Marina, as she hit the dance floor.
Instead, he began to scan the crowd for another familiar face.
