Does Killua have a crush on Gon? Watching the latest 3 episodes of Hunter X Hunter 2011 ( 114 - 116) I started to wonder. Does Killua have a crush on Gon? Or am I just mis interpretating his text lines?
Short answer: There is little or no canonical love from either Killua or Gon toward the other. If any kind of love is to be clearly deduced, it should be regarded as platonic or brotherly.

Longer answer: From childhood, Killua was deprived of the experience of having friends. He met Canary, a guardian of the Zoldyck estate, and wished to be her friend, but she disciplined herself to not have any personal feelings for her employers (Killua included).

Fast-forward to the Hunter Exam, and Killua meets Gon, quickly discovering that he wants a friendly relationship with him (attempting to sever the ties to his former life as an assassin). In this case, you have to understand that Killua doesn't know how to behave around friends. He does his best to be himself, but he doesn't want to push Gon away. Even in a relationship as simple (to you and me) as friendship, Killua doesn't know how to manage his feelings.

As a result, personally, I would say that Killua just shares a really, really strong best-friend relationship with Gon, and feels a personal need to protect Gon, which can appear romantic at times. Gon, being the nutty lil' boy he is, also tends to express his friendship in odd ways...



Now, taking all this into consideration... It doesn't honestly seem like there is any romantic relationship between them (though the mangaka seems to have thrown in a few choice lines to tease fans with).

In the latest episodes you mention, Killua does have some very odd lines.



He states that if he asks Gon what he means by "Let's go!", then he "won't be able to go back." This sounds a bit lovey at first, but I think Killua is honestly more worried about Gon, almost like a brother might be. He understands the rage Gon holds within, and is deeply worried that Gon might be headed down a spiral of destruction. With good reason:



Sadly, though, asking about something like that could almost seem like a betrayal; remember that Killua doesn't want to do anything that would endanger his friendship with Gon.

So while I think it's important to recognize that there is no canonical love in play (at least in the anime, I haven't read past the manga's equivalent of episode 115), I think their relationship is designed in such a way to make us ask this kind of question. Their relationship is far from simple, and that's probably one of the things that makes it so compelling.
