[ Hisoka is purposely trying to bug Tanjiro to see if he has any bite to him. If his friend is seemingly "threatened" or in a threatening situation, will that innocent air about him change? He can't tell. He really can't tell much through a screen so can only toss out bait here and there.

"Hello? Hello? Who are you?" His actions and words try to figure these things out. Inosuke was easy to figure out, but this one ... is he really a dud? He might be? But maybe not? Hm. ]

It's Hisoka, yes. [ His head cants to the side as he smiles. ] It's hard to tell. I'm going to say that he probably doesn't. Something tells me that he just doesn't think long enough to make sure he's saying the right name.
