"If that's what you think, you haven't been paying close enough attention to my ass," John says, cracking an eye open to first squint at Lambert, then at Lambert's offensive cigarette bumming hand. Both eyes come open when he puts the effort into rolling them, but he does swing his feet back down off the table and lean over some, just enough to give himself easy access to the pocket with the pack in it. Both that and the lighter get handed to Lambert because he doesn't feel like digging one in particular out.

"Don't smoke the whole pack and try not to piss on any exposed wiring, all right? I have enough sister problems without yours tearing me apart because I let you die in the stupidest way possible."

The last part sounds like a joke. Yeah, it's probably a joke.
