"My wand's not in your face, it's in my hand," Gerard pointed out pleasantly, and leaned in a little harder. "And I'm just asking a few questions, keep your fucking robes on. Don't give me that 'I'm not doing anything' bullshit. You're doing something, I can feel it."
Still -- it wasn't a malignant something, even though the guy was glaring up at him furiously. In fact, whatever magic it was that had boiled up around them was already settling, going dormant. And when Gerard inhaled carefully, he didn't smell blood, or rot, or anything suspicious, really. Just coffee -- good coffee, Gerard blinked, momentarily distracted -- and the scent of warm weather, and garden dirt, and Floo powder.
Huh. Maybe the guy was telling the truth. Gerard warily eased back a fraction; the guy might not be pure evil, but he still looked like he wanted to break Gerard's nose. "New professor of what? Can anyone back that up?" he asked finally. Gerard wasn't about to take his eyes off the guy until he knew for sure what was going on, but if he was a professor, then probably someone would know him. If not, well, Gerard wasn't above Stunning and dragging him to Schechter for corroboration.
