Mairen looked up at Isadora's entrance, half expecting the Ravenclaw to be frustrated that she had to meet with the redhead. For all the older woman knew, Isadora actually was annoyed with her, but was hiding it fairly well. The one who perhaps really should have been frustrated, though, was Mairen herself. She wasn't sure how to explain things without actually writing it out. She supposed it could always be burned in Keiran's office after their meeting ended and Isadora went back to class. Avery would be willing to help her with that, Mairen knew. So it was probably the best bet she had, considering Non-verbal magic had never been a skill of hers. Figures. Anyway, she couldn't use any sort of spell to write it out for her, so that would have to be done by hand.
She shook her head at the second question, biting her lip as though it mattered in some way or other. It wasn't like it held back any secrets or words, considering Mairen couldn't form those. Or, vocalize them, at any rate. She turned and walked around the desk, searching for a pad of paper. Opening a drawer, she found files and quickly shut it back, uninterested in getting into trouble by messing with them. Instead, she went for the long drawer underneath the center of the desk, and found a yellow pad - probably brought in by Keiran himself. A pen, too, was there so she took it up in her hand. Surely Isadora wouldn't begrudge her necessary quirk. After all, the girl had seen her at the wedding, unable to even say her vows.
Not that they necessarily mattered at that point, mind, considering he was gone. Mairen figured that hers would always be true, even if she didn't understand Scorpius's take on things.
Still, she passed Isadora an apologetic look, supposing she should have written it out before the Ravenclaw arrived. Deciding it would be better to go piece by piece and explain more thoroughly, she wrote out her first point.
I know a secret, and I could get in huge trouble for telling you. In fact, your family would get in trouble, too. But it's about a murder of someone who deserves to know what happened to his father. It could take Ana Levski down for good. I want to tell you, but it's absolutely required that you not tell anyone until we figure out what to do. I can't solve this on my own, and I don't really have a family to talk to outside of yours, so...
Her writing slowed on the last sentence, but she knew it needed to be said. Otherwise, why would she have gone to Isadora in the first place, right? So she passed the pad towards the younger girl, clasping her hands tightly atop the desk. Her lips curled in briefly, but she forced herself to relax as she waited for some sort of agreement or refusal.
