What?! [Gon shoots back incredulously, then raises his eyebrows.] It's not weird!!

—I mean, I don't think so, anyway... It's not like I've seen it before. But if it is weird, I don't think it's the same kind as the other place! Don't be mad at me!

[Gon's whining like a brat, but it's clearly in humor. he wants to joke and say it's too early for Killua to be getting mad at him, but saves it. because it's not, really. Gon's lucky they're hanging out at all, and he doesn't want to call attention to that and ruin the fun they're (he's) having.]

I know I said I'd take you to places I'd already been, but I thought it'd be a little fun to go someplace new together in this world, too...
