Vincent , Genesis & Slytherins
Vincent snorted at such a dumb statement, "Course they do it professionally, Flitwick's got all them trophies, don't he? You can make a lot of money doing it too if you're good enough." He took in the potatoes on his fork and pointed it toward the staff table, "Plus, Uncle Amycus used to coach a whole slew of the best back in the day."
Having grown up around people who looked to professional dueling as a career option he thought it was stupid that someone wouldn't be aware of the lucrative element of the sport. Course, he was completely oblivious to and uninterested in knowing Genesis' lack of background in the wizarding world. Far more content just thinking she was dumb and he was smarter on the subject.
