[Compared to the antisocial wonder himself, this kid is "outgoing." Especially on a relative level, and especially from L's somewhat warped perspective.

Still, his talent is a sound and reliable one, and once that crowd is gathered, he knows it can make up for any charisma they might lack.

He briefly and crisply explains what's going on to the crowd, and many of them immediately dismiss it as impossible to remember the position in the deck of every single card... but that's a good sign. They're expecting a really amazing trick, and the truth is that it isn't one, and he genuinely can remember. It works on two levels, because long after they're parted from their money, they'll still be wondering how he did it.]

My assistant and I are accepting tips... but if you want to place bets, we'll pay you back double what you put in if I'm wrong about the card.

[Well, now people seem really interested. To the kid at his side, L lowers his voice and says]

I could keep calling you "my assistant," but what is your name...?
