[ While Stiles speaks, he takes the opportunity to look him over again. Before he'd sought out evidence of a warrior in his stance and visibly searched him for weapons, beyond whatever it is he has tucked away in his pocket. Now he looks for more.

Defensive, with a guarded expression. Slim, not skinny, and tense with an energy that he seems to be holding back just in standing there. Jumpy, perhaps. Taller than Sasuke himself, though not by enough that he could mark it as significant. Young. Younger than him? That'd be his guess, at least. ]

... your mouth is still bloody. [ The rest of his point doesn't need to be vocalized to be made, not if Stiles is as sharp as his pitch makes him sound. "Spit it out before you say you haven't done anything ridiculous." ]

If we share the same goal and you contribute, I have no reason not to work with you. If you slow me down or don't offer anything meaningful in return for protection, I'll take you back aboveground and leave you there. [ And in this, he is as fair as Uchiha Sasuke can possibly be. And fairer than a good many other residents of Kenos would be. ]

Give me your name and identify the leads you have so far.
