As she watched him walk over to the door and shut it, Marlene could not help the reflexive tensing of her shoulders. It was a small gesture but a closed door could mean a multitude of things. While she trusted Professor Ogden, Marlene really had little reason to have much trust in anyone here at Hogwarts right now. She knew full and well what possible recourse could be in line for her if certain truths got out. A shut door could mean a lot of different things, but most of all it as closing out the outside world. If he was keeping her in or others out, really she had no idea.
But she kept the rest of her posture as composed as she could possibly manage. Nadine had commented growing up that really what Marlene should go into was acting, she was remarkably good at it. "No, of course." she agreed easily, letting her eyes linger on the closed off escape for a moment longer.
Marlene watched him curiously as he pulled out two chairs. For a moment she stood there, not really sure what to do. Did this mean this was going to be a long chat? That would lead her to believe it was not about her grades. But after that moments hesitation she relented and took her seat, setting her bag down next to her. As she listened to the question she quickly masked her face in confusion to cover up the panic that rose up first. "Have my grades gone down?" she asked, sounding every bit sincere in the question.
