Okay but can we take a moment to talk about how truly traumatic Leorio’s past really is? Like, I know we all talk about how terrible the other three’s childhoods are:
Killua living with a physically and emotionally abusive family, Gon with his father abandoning him, Kurapika’s clan being killed.
But I think we tend to forget that Leorio had just as much of a tragic background as the others. He watched his friend die. Right before his very eyes.
And then that hard reality sets on him; he could have survived if they had money for medicine. It was an entirely curable sickness. But all he could do was watch as his friend collapsed. And let’s just think for a moment; Leorio lived in such an impoverished area, there were probably bound to be other people he knew who suffered from the same sickness or a different illness that could have been saved from that miraculous money antidote.
So Leorio could have seen far more death in the course of his childhood that we may not even know about.
This becomes even more of a pressing issue for Leorio, especially concerning Gon. Because seeing Gon just laying there, practically charred skin and bone wrapped up in medical tape, physically and emotionally kills Leorio. Not just because it’s Gon and he feels so connected and attached to Gon, but because it brings back those memories. Of when he couldn’t do anything but watch someone die. And he thinks “Not again. I will not stand by and watch someone die again. I will find some way to heal Gon. I will invest every single piece of fame, fortune and time to bring Gon back.”
And when Gon enters through that door in the middle of the election, Leorio is so happy; so overwhelmed to see Gon alive and well. He’s so, so ecstatic that for once,
someone was finally saved.
