He blushed a little bit, "I promise, the door didn't slam on purpose. I'll never forget the outrageous Bat Bogey hex you shot at Mintumble when she thought it would be hilarious to sneak up and tap you on your shoulder when you were working on a fraggin' autopsy." He shook his head. He had a healthy sort of fear for Cassandra. "Not that I'd sneak up on you anyway, or anyone, it's just not something I find funny," despite being the son of a renowned jokester, scare-laughs just weren't funny to him.
He shrugged, looking more deeply into it, "I know one when I see one. I got pretty extensive antidote and poisons training when I started here, but not much otherwise. That one's pretty distinctive though. Who'd you go to for that? There are only a handful of Ministry-approved potionsmasters who do that, let alone so well."
He cocked his head to side and gave her a penetrating look, "You of all people know better than to ask that. Unless a person's willing anyway. Why would I want anyone to know what I smell in that? What do you smell?" He didn't ask it combatively, just thought it was a good moment to turn the question back on her, curiously. Truth was, he smelled an... odd... combination whenever confronted with Amortentia, and he'd never smelled anything else like it, not on a person or in general.
