User blog comment:FinalFlash18/Happy Birthday ....../@comment-48285-20140505172603

I saw this one pic on Tumblr that was Gon, Killua and a birthday cake that had "12" on it (like, the number candles). And Killua said, "Dude, I swear, you were, like, 12 last year". So, happy birthday, Gon! May you forever be age 12. Along with Killua, of course.
