Klaus finds himself joining the laughter, but he carries on for a minute after realising that John himself has stopped. His face falls a little, because he has no idea why anyone else would be as upset by his half-joking delivery...oh. Oh.

"Shit, you too?" he asks, incredulous. "You see them too?" That's the only reason he can think of for that particular reaction.

He takes John's next comment in stride, waving a hand. "Well, I mean, they did say we're in Hell so it's probably a moot point. I figure everyone here is a dead person. But that's not what I meant, which you telegraphed loud and clear that you know."

He could just drop this subject like it's hot, but he's never met anyone else who could see the ghosts and spirits before, so he can't help but wonder.

He waves his half-empty drink vaguely in John's direction. "Oh, I didn't outgrow them. I just drink to forget."

That's half true; he usually does much harder things than drink, but any port in a storm and all that.
