Well, that's more than enough for Koby to understand that the topic isn't Iggy's favorite. So he leaves it, moving onto something a little more pertinent (to him): "How much ocean is there, where you're from?" He's not used to a place with this much solid land, so he's gathering information.

There's a moment of hesitation, then -- because Iggy seems to be a genuinely nice person, and Koby wants to give him the benefit of the doubt: "I've never given it a lot of thought, so I suppose it's a little weird for me. But I'm not uncomfortable, exactly. It's just new."
