Re: Arcturus and Cassian
If Arcturus thought about this explanation for a little longer, he might realise who the ‘bunkmate’ had to be. He doesn’t, though. He hears it, and assumes that it must be another boy, because boys and girls sharing the same room goes so far beyond the boundaries of what’s proper that it’s unthinkable. The dormitories at Hogwarts are large, but are always divided that way.
‘I suppose you can bring him along, if you’re vouching for him,’ he replies, not sounding too concerned about the matter. ‘There will be plenty of room. Just make sure he knows what to expect.’ He softens the abruptness of this last statement with another small smile.
