[Mello refuses to react further, keeping his expression hardened in defiance. He does not move when the other man intrudes upon his space, for often that is a tactic he himself employs — claiming personal space to unnerve another, if only slightly, so that he can play out his hand. Instead, he meets Sherlock's stare without even the slightly hint of discomfort, a smirk of his own coming to play upon his lips. He recognizes this game — knows it all-too-well as one of his own — and believes that if the seeds of this encounter are to bloom into something akin to a battle, he will win.]

All those inferences, and yet you can't figure out why I set this up?

[Though Mello supposes he does know, and is testing him — trying to see what answer he'll produce, maybe see how well Mello can play, or what move he'll use next. He therefore allows his question to remain rhetorical, choosing to respond properly.]

I thought you might be of some use to me.

[And perhaps he wasn't far-off in that assessment, as he has clearly encountered a man whose abilities might just rival his own. Only time will tell if that is the case, but Mello, too, recognizes the similarities.]

You didn't answer my question. Is it because you're afraid of what I might see in you?

[He's still wearing that grin when he reaches inside his pocket to pull out the only chocolate bar that has managed to come with him to this city, but he doesn't unwrap it. Instead, he holds it up to the other man.]

Tell me...are you an addict?

[They all are — people like them. L allegedly had his sweets, Matt has his video games, and Mello has his chocolate. They may not be standard addictions, but it is the mark of a true gifted individual — at least in Mello's opinion, having grown up around gifted children and witnessed addiction in its myriad forms.

He partially unwraps the chocolate and takes a bite.]
