It does fuck me up a little that in episode 147 of Hunter x Hunter not only do they change the ending back to Reason (a song about Gon and Killua's friendship from Gon's perspective), but they also edit the song differently than how they did for the GI arc, so that as we see Gon and Killua sadly turn away from each other and walk away, it starts slow and ever so sorrowful with these fucking lines
I’m right here, by your side, I’m the closest I can be
And I’m fine, I’m content with this arrangement for now
Please tell me gently the rest of your dreams
That you started telling me one day long ago.
Like what the fuck. What the hell dude. Why would the anime directors do this to me, specifically.
