Sasuke doesn't recognise the person standing outside the empty house on immediate sight, though there is something familiar enough about the face that he can probably assume that he knows the guy. Then again, given what part of the village this is, he usually not only knows but is in some degree related to the people wandering around.

Not that this one's doing much wandering. Was he looking for someone, maybe?

"Hey," he calls down from the roof he's been travelling across, dropping down with another curious look -- trying to match a name with the face. "That family moved about a month ago." Sasuke had been detailed to rally some of the younger cousins to assist with the move, to his considerable displeasure. "Who were you looking for?"
