Of course,being used to his fellow witches and wizards, apparition wasn't entirely that uncommon, a rarity of course but he was hardly startled by the strange bloke appearing out of thin air. Instead he merely scowled at the bloke, taking in his strange clothes rather then his words. No wizard or witch in his time would have, willingly, participated in such a prank by children, which meant perhaps the students weren't behind it at all?
The thought churned in his head a moment before he lowered his wand from the other man. A step, at the very least, towards being civil, considering that he'd done nothing to him besides attempt to placate him.
"What manner of magic is this place, friend?"He questioned softly, frowning a moment. Perhaps he'd finally gone mad like Helga often teased him about.
