Yeah, that's exactly what I meant, Shinta. It's a huge risk to go alone, especially with the little knowledge anybody has of chimera ants. Yet it would also be a huge risk to allow the king to be born, creating a situation where the ant colonies could spread rapidly. Yet despite this a rock and a hard place situation Kite thought he has enough margin to take Gon & Killua with him, to teach them along the way. So, he's only 50% concentrating on getting to the ant colony on time, the remaining 50% spent on looking after the kids, advicing them, and granting them time to fight random ants. That's underestimating something he doesn't even fully understand, plain and simple.

Now, of course I understand that this is a shounen show and it would have been ridiculous to leave the main characters behind, so that was unavoidable. I certainly prefer this to the alternative of Kite telling the two to stay out of NGL, those two sneaking after Kite nonetheless, getting into trouble, Kite saving them and having no choice but to allow them to continue with him. In any case Kite himself seems to be noticing of late he has neglected to take something into account.
