The medic's not the only to state that Gon is 12, chapter 220 as well, every time this kid's age has been stated, it's always been 12, same for the anime adaptations and tankobon, it's literally stated nowhere that he's 13 or 14. If Togashi wants him to be 12 for life then so be it, so him and Killua being 14 via the timeline belongs in the Trivia at best.
