Well, currently the teachers are occupied with bring order, keeping students from hurting themselves or others and preventing Satori from being killed so Colette can't exactly ask any of them. So what better way to get the details then to ask another student. Not to mention, maybe Mar's appearance would help in Colette focusing her mind on the Nag rather then her thirst? That could be a stepping stone for her to controlling her blood lust, couldn't it?

OR did I misunderstand what you meant?
