Harry smirked. "Well if we could cover them all that would be a good thing, but whatever else potential Dark Wizards there are haven't created much trouble for us lately. Why don't we focus on the one who has?"
He leaned back as Percy started working, nodding every now and again. "I'd say the same," he said. "It's one of the hardest professions out there as far as I understand," he said, wincing as Percy went on to remind him his past mistakes.
"You don't think a time turner and telling my younger self to shut up would help, do you?" Shrugging, he smiled a bit. "Not much to do about that now, though, and yes, the most popular would probably be a good idea. See if you can find someone who has been in business longer than the others, or has a long tradition in the family or has been known for making wands suitable for the Dark Arts," he said. "Anything that makes one or two of them stand out. Anything that might attract Riddle's attention."
He didn't expect much more than that either, though there was the hope that they'd get more information - or a chance to catch him, or kill him, which ever suited the situation.
He frowned. "I'm not sure," he said. "Besides I didn't say it was a victory," he added with a smirk, though clearly he saw it as such. "To be honest I don't know how much I could share without giving away information that I am sure Voldemort would love to get his hands on. Though maybe." He sighed "I don't know, I have no clue what I could include or not."
