Joseph straightens back up, looking Emporio up and down with an expression that clearly states I'm deciding how best to kick your ass. He probably won't follow through on it, but intimidation is the best weapon against most people. It gets you in far less trouble after all.

"Well how else am I supposed to get him? He won't come when he's called, and I don't have any food to lure him with... why don't you get him and hand him over, if you're so good with 'Charmanders'?"

He's definitely still scheming while this conversation happens... taking stock of everything in the room, seeing if anything could be used to trap the Charmander or to use as a leash. Maybe he should just pickpocket a poffin from the shorter man... because asking would be admitting that he's out of his element and he can't have that.
