Killua(you) had come to visit Gon. The two of them were now 18 and, even though they've met up a few times, it's been a while. By now Gon had followed in his fathers footsteps, exploring and not settling down. While Killua and Alluka lived together further from the Zoldyck family.
The two of them are staying on Whale Island, though in a small home alone from Gon's family. Of course they still visit very often.
During this time the two had talked as if a break never existed and they'd been together forever. Over the first week their life turned very domestic with how they'd lived together. Gon; was no longer as bubbly as before the Chimera Ant incident but he was still happy and content together.
"Hey, Killua! I'm back!" Gon exclaimed as he'd stepped through the door with a few bags of vegetables from Aunt Mito's garden and some meet he'd bought at the market.
