Q, who meant he understood that the matter would have to be discussed (and that makes him really nervous!) swallows again. "I can understand that," he allows with a small smile. "Hogwarts can be very confusing, even when you're used to it." He frowns. "Which house became extinct?"
"Well," he begins slowly, "since no muggle could have triggered the spell and it didn't hurt anyone," he looks at the chair with askance, "or it hasn't yet any way..." Q shrugs. "I still think it's some sort of prank. Or some kind of test. I just wish I could figure out who did it." He waves a hand at the room. "None of my wards were triggered, so unless John has very well hidden depths..." a sudden thought occurs to him. "You reckon we should test the rest of the furniture?"
Many, many apologies for the delay. It has been a bad day at black rock. :(
