Character: Killua
Seeking Approval
Two years ago he was told that he still smelled like Gon - maybe by now their scents are so interwoven that no amount of water or scrubbing could separate them, like a signal to the world that only the most skilled can perceive but is there regardless. Something that indicates they function as a pair, even in those rare occasions when circumstances set them apart.
With any luck, when they finally get to famous, elusive Ging Freecs, that is what he will notice on Killua - the scent of his son's constant presence, and not that of blood too easily spilt.
