[Sokka looks shrewdly at Skulduggery. There's an eerie trust for the detective that he can never quite explain, but the trust is there. Though doing it will in part violate the trust Hiro has placed in him. Though technically, that was all a ploy to keep him from spilling to Zanru, not Skulduggery, so... maybe it can still work?]

Aaaaalright.

[He holds up a hand and starts counting them off on one hand.]

There's Krei. Alistair... Alistar, something or other. I don't really know him that well. Haven't talked to him all that much. Seems pretty busy and snobby.

Then there's Callaghan. Robert I guess is his first name? Again, don't know much about him. Though the guy's voice doesn't sound like him. Doesn't sound like any of 'em though, but that's not saying much.

And then there's... mmm, Tadashi? Probably not since he's the kid's brother. And the kid got banged up himself by this guy.

So... I guess those two are my first guesses.
