Sasha simply nodded, though he was highly doubtful of any secret wizarding college. After all, what motivation would they have for keeping it secret from other wizards? Even if they wanted to keep their, presumably, less-then-traditional interests out of the mainstream, wouldn't they still try to find a way to recruit Hogwarts students?
At the very least, Professor Trishna would have known, and said something, to Sasha. Sasha had to believe he would have heard of it.
But, Fauna started excusing herself and Sasha nodded, pushing himself to his feet. "I - of course. I've kept you too long. I - I'm sorry. About everything."
At about the same time, a self-contented looking Giada appeared in the study, bearing a tray of afternoon refreshments. However, the elf's ears drooped slightly as she saw their guest preparing to leave. Just as quickly, her ears pricked back up and she set the tray on the desk and conjured a cloth napkin and a disposable coffee cup and bundled together some of the crackers and cheese and poured the tea into the cup.
"For the road, Fraulein," Giada offered, with her heavy accent as she extended the refreshments to Fauna. "Giada knows he won't eat them." She cast a despondent glance in Sasha's direction, prompting an awkward blush.
Sasha sighed and shrugged, taking a few steps towards the study door. Remembering the purpose of the visit, he nodded towards the rolled parchment. "Hopefully, that will settle everything. Just let me know if I need to supply anything else."
