Ben just cupped Fionn's shoulder for a moment and gave him a half-smile. Naoto dashed off for God knows why and left the two alone for a silent moment. Naoto could stand to calm down a little. You don't get anywhere racing around. Ben gave their boss a nod and followed suit. Instead if running off he strolled through. He moved slowly but he scanned thoroughly, pausing at alleys to look down them. His expression didn't change much as he followed Naoto. He only followed his trail, really. He wasn't keeping pace not did he want to. As he passed a thin street he did actually find four audience members, disoriented and confused. For the sake of immersion and since he was feeling nice he explained to them that due to the sheer size of the crowd, Prospero missed a few times as he teleported people home. He had been 'sent' out to track down the missed 'ports.
Once he finished explaining that, he sought Fionn. He wasn't far off and he seemed friendly enough. It would be wise to build bridges within the group, if it was only one. "Fionn, I'll stick with you. We'll be more successful with a tandem effort." Ben said as he walked over. "I don't recall you sparring with Sonya the other day. You should have spoken up." Considering they'd only just met there wasn't a whole lot to discuss. But a mutual respect and/or fear of Sonya could almost be ensured. With such terrifying resources why did the Vongola even need kids like them? They weren't hitman they were high schoolers. They couldn't shoot a man, they could barely defend themselves. Granted, Ben had never tried to shout a man but he'd never had to grapple with the psychological effects of ding so, either. It could come naturally, he supposed. Perhaps that's why they were chosen? Because somehow the Vongola knew they were cold-blooded killers? That felt like something he himself should know before others.
