Jack pretends to not really notice anything going on around him and strolls to a shelf of items near the door, still humming, but etching the face and garb of the man in his mind. He pokes at one of the items for a moment longer then with a brief, Nonchalant wave back at N'Kwane, trying to look as much like an uninterested shopper as possible, Jack steps out of the shop.
Once outside, he scans the street for the mysterious sleeper and will attempt to follow him at a distance to see where he's going... he can come back later for a closer look around, assuming he sees something he thinks significant.
