He's got a feeling this guy is altered somehow and he's probably right, but Han assumes it's from some kind of drug. Which, they have in a galaxy far, far away. Matter of fact, that was, more or less, his first unfortunate job in the smuggling world.

One thing he doesn't want to do is startle a guy that's on something. Best to just play nice with those types. Least until you know what you're dealing with, though, he's glad to have his blaster. Just saying.

"Well, I'm Han." He says, with a little less attitude than he used on him before. "If you tell me your name, we can be semi-acquaintances."
