Harry would bring his hand to his chin... Hmm, good info he's gotten here, and the man would also take out a small vial and get a bit of Ryuji's blood from the wounds. If his boss breaks him out and takes him back, that bit of blood can lead him right to their hideout.
"Well, this is all very nice to know. But I'm sure my good friends Chicago PD have more questions for you Mr. Terriost, it'll be nice meeting them for you no doubt about that!"
Of course, one wonders why Special Investigations is out here rather than somebody else. But well Harry's not going to complain, he has an island in Japan to look into soon. And with that, the man would drag Ryuji out to a cop car, they'd quickly handcuff the boy and call up an ambulance.
Gunshots put him in need of medical care after all, and while Harry's in no danger of legal issues,
he'd feel pretty bad if this idiot bled out after being no threat. Either way, the Wizard comes back in and looks over at Yumina.
"So... What exactly were you gonna do if I didn't show up? I mean, this is kinda my city so it wasn't a totally unsafe bet. But geez you could have gotten really hurt on your own. How much gunfire do you think you'll live through Yu? Trust me, not much is the answer."
Despite his words being perhaps a bit harsh, the man's tone betrays his concern. He feels vaguely responsible for her safety at this point, and he would be pretty damn disappointed in himself if she gets hurt trying to play detective or something.
