User blog comment:MrPedroNorris/Could "Dark Continent" be Leorio's saga?/@comment-14902757-20151017235808/@comment-10528819-20151018021825

I can see what you are saying, the "purpose" part I would argue that Killua also don't have much, he wanted to leave his house, his father let him, and now he's traveling with Gon. However this didn't stop him from beeing crazily developed .I also don't think he will need ti squeeze much from Leorio, because so far on the series he's shown a strong trait, he is Kurapika's call back card, he's the one that tries to keep him from gettign total insane, and that's already stabilished. On the time part, first of all you can be right, and I hope you are, when in another answer you said he might not be serious and it beeing more than that, and two a saga can be really long if needed, specially with a money maker like Hunter x Hunter, only the Chimera Ants arc resulted in 2 seasons of adaptation so I don't think they would need to rush his development. Another point I have is, again in the Chimera Ants arc, Killua shared his time with other really interesting characters like Netero, the Ants, and still he managed to get enough time to all of them
