"You were at all the trials, Albus," Professor Reynolds snaps, "You know the truth of the accusations as well as anyone."
He regards her, expression unreadable, then inclines his head. "Professor Severus Snape was indeed accused at the time," he says, gently, "But I found the evidence exonerating him rather convincing. I do not believe he is a threat to students."
"Does," Professor Reynolds takes a deep breath, "Does he have a bloody Dark Mark - "
Headmaster Dumbledore replies, voice still pitched to be soothing, "You know as well as I do that the Mark was placed even on those who were controlled or coerced, Fay."
Professor Reynolds' expression is incandescently furious. "You..." Deep breath. "I won't detract from this complaint," she says, voice tight, "By delving into this particular disagreement at this time. The complaint submitted, taken on its own, regardless of anything that did or did not happen prior to nine this morning, represents unprofessional and inexcusable behavior on behalf of anyone representing this institution, let alone instructing its children."
Headmaster Dumbledore folds his hands in front of himself, calmly. Almost serenely. "Prior behavior is rather illustrative, however, when considering anything that might be done about a complaint, and Professor Snape has a rather exemplary record. Furthermore, he has the right to explain his side of events to me. I will speak to him this evening, after the last of his classes." He turns to look at the other students. "Do any of you have anything to add - ?"
The others all nod, adding at the very least, "Ellie's not lying" or "Anathema never lies, even if she did something wrong." (That last from Lisa, one of their dorm mates.)
Professor Reynolds watches through all this, expression stony.
Headmaster Dumbledore nods through their recounting, then: "Well, this is quite a mess," he says. "I promise I'll see that it's all straightened out. Why don't you all go and get some sunshine though?" He chuckles. "You seem to have a surprise free period, after all, and this is quite a lot to be worrying about."
