[ Even if Killua can't see it, Gon is smiling. Beaming and brimming with excitement over being able to come along. It's weird that he had to ask permission but he doesn't give that much thought.]

I don't think Hisoka would mind sitting alone. Not if both of us are there. [He's not being conceited, he just knows Hisoka. As much as he hates to admit it. Whatever, switching topics.] It'd be a lot of fun, Killua! Thanks for letting me come along.
