see i feel like this is such a good example of their relationship tho and shows how complex and nuanced it is ;-;

like theres a lot of things going on in here but some of the main parts are

gon wanting to ignore killuas injuries and how that in a way is a show of his childish selfishness. i think this gets brought up the most w this part

but also how gon flat out just takes killuas word for it. killua wants to continue and so does gon and thats literally all the two need. killua would do the same if the situation is reversed!! they trust each other in that way

but also how much killua loves being relied on by gon and how he really really desperately wants gon to love and trust in him. gon readily supplies this, which isnt a negative thing, but it ends up causing a LOT of trouble in chimera ant arc OBVIOUSLY that killua is willing to go above and beyond for gon
