[...No, his reply doesn't quite make sense. Thanks for noticing. In fact, he's got some suspicious eyes going on until the wallet comes out, and they fade entirely when the cash joins it.]

Wait a second... Five... Ten... Carry the one... Twenty-- Oh, crap, you're loaded!! [Of course, realizing that comes part and parcel to blurting it out. Still, he hasn't seen that much money since.... he doesn't know, forever maybe. Close enough to it. So, yeah, he's looking at it with the gaze of a guy who isn't jealous solely because he can't count how many dollars he doesn't have.]
