Prospero looked around and saw that the strange English girl seemed to be paralyzed with fear. The magician guessed that if he didn't know any better and had just watched two people appear out of thin air and seen a crowd disappear, plus heard the word 'Mafia' over and over again he'd be a little worried too. If nothing else, that red-haired woman was enough to put fear in just about anyone's heart. He puzzled over it for a moment and decided that as long as she was in a state of heart attack-inducing terror he probably wasn't going to get a very good tour of the town. Plus while he tried to be stoic and keep cool externally, seeing someone obviously isolated and scared pushed on his empathy-buttons a lot more than the masked boy was willing to admit. Thus, as one of the few English speakers in the group and the only one who didn't have his head totally up in the clouds or...wherever that Michael guy's brain seemed to be, he decided to take action.

"Hey um...don't worry so much, okay? These guys are really just ordinary middle-schoolers mostly I think and all the disappearing stuff was a really fancy magic trick! The red-haired bruja's pretty..yeah..but the good news is we're all kinda running from her at maximum speed, y'know? Um, anyways she made me the official translator and I'm totally not a bad guy who'll make you disappear, honest! If you want I'll even give you an autograph! Oh um, the black haired chica says she's ready to go when we are by the way, so let's get this magical mystery tour on the road, yeah?"

Prospero hadn't spoken English in a little while, or for that matter really interacted with people in a context outside of talking to fans, interviewers, businesspeople managing him and various mafiosi and underworld types on his quest for vengeance, but he was pretty sure he did a good job reassuring the English girl, yup! Now for the American tourist and the black-haired girl! He was gonna make so many friends and then being a dark avenger dedicated to perfection wouldn't be so lonely! Yeah! He started switching between Italian and English as he chatted with them, or tried to chat anyways. He was more than a little rusty. First he turned briefly to Michael, smiled and winked before talking in a more energetic, excited and childish manner than usual.

"Where in the U.S. are you from?~ I feel like haven't been there in [i]foreeeever[/i] and I can't place your accent but it's nice to meet another American!~ What brought you to my show? I'm in a good mood so autographs are free! I'll sign anywhere you want, 'kay?~" His plan of attack here was basically to use the sort of behavior that worked with most of his fans. As far as he could tell, this guy was just a civilian tourist anyways. He turned to Jakki,and switched to Italian while keeping the same mannerisms 

"So I think we're ready to go!~ Much more importantly what's your name and what's the nature [i]exactly[/i] of your relationship with Naoto Alato?" The fact that he'd accidentally phrased a question about which Guardian she was in a way that probably seemed much more embarrassing and personal never crossed his mind.
