I think it’s really interesting how you can see that Wing ends up regretting teaching Gon and Killua nen bc he’s unable to control their abilities and their tendency to jump into action. I also think it was foreshadowing to how they’d go too far and lose control
During the hunter exam Gon felt guilty bc he wasn’t there for Killua when Illumi attacked him, imagine if he knew all the pain and trouble he went through while Gon was hospitalized
