Arcturus' face fell a little at that last question. He remembered when he had first arrived, how certain he had been that it was all just a great misunderstanding and that his father would be along to collect him in a matter of weeks, if not days. But there was no sense in burdening someone else with his troubles, and so he just gave a curt nod. 'A while,' he confirmed. 'Although the school only opened last month, so you needn't fret about being new, and they won't put you in with the first-years, either. I'll show you around the place, if you like.' There were no prefects at the Preyan magical school, or else he'd have left such things to them. Under the circumstances, it didn't do any harm to be helpful.
He brightened up a little as he turned back to the matter of the broom. 'Most people can fly where I'm from. Not all of them can fly well, but that's another matter. I fly well,' he added with a small smile. 'I was on the House Quidditch team back home, and that's the greatest flying sport there is.'
With that, he shuffled forward a little on the broom and maneuvered it closer to where the other boy stood. 'There's a cushioning charm,' he explained, gesturing towards the space he had made behind him, 'so it's far more comfortable to sit on than it looks. Give it a try, and I'll fly nice and sedate like we're off to a tea-party if you like.' A fractional pause, and then, before his new acquaintance could respond, 'I'm Arcturus Black. I ought to have said that first, I suppose! You can call me Black, everyone at school does.'
