Vash the Stampede. Nice to meet your acquaintance, kid. ( big, big grin on his face as he moves his hand from left to right in a kind of 'hi' wave, as opposed to a standard handshake most people are probably used to. but he doesn't wanna get his hand smacked away because he sure gets the sense that this teenager is a little broody, as... most teens are. he remembers going through puberty. something like that. )

What's your name? You looking for your friends? You can describe them to me. Maybe I saw them around here somewhere. ( because he's definitely met a few people already. this city's a strange one. there aren't any original inhabitants here, as far as he can tell. and he can definitely surmise that this young one's not native to this city either. why else would he be looking lost, upset, angry? all of the above? )
