Keiran was tired. Not because of schoolwork or Quidditch practice - or even brooding, which he was very good at. Instead, he was tired because of one Jack Dyllan. She'd been pulling all manner of pranks on Keiran and at least one other Slytherin on the house team, at least to the captain's knowledge, and now there was word of her getting into a physical fight with Matt Lestrange as well? It was frustrating, if only because it was distracting. And this was not a year that the team needed any distractions.
As worried as Keiran already was about his final year -- NEWTs and career goals and everything else -- he still had hopes of going out with a win. He wanted the house cup. He wanted to destroy Gryffindor, if only for the bragging rights over Jack herself. And the odds of that happening would go even further down if she kept messing with him and his team.
So after dinner one day, he positioned himself in the doorway, arms crossed, and stepped aside just in time to block her path out of the door. If she was going to make a fool of him, he wasn't going to sit back and have this conversation in private. He knew he might not manage to make less of a fool of himself, but he wouldn't look like a coward that gave in when someone pushed him.
"I understand," he began cooly, expression blatantly unimpressed, "that you think you're quite funny." For someone who called Jack a friend, Keiran wasn't trying very hard to seem, well, friendly.
