Well that can't be true. Even without 4kids, there has to be a fair number of scenes on just a visual level, right? I haven't seen it all through since the 90s so I could be wrong, but don't mistyfags have a point when they say Ash showed interest? And just how much was changed in intent, exactly - when in the second film they're still making dropping moments like Misty reacting to someone kissing Ash?
It's all fairly loose stuff, yeah, and I see no reason for anyone to be upset both characters moved on - especially in Japan - but I'm not convinced it was all headcanon. The japanese version, that is.
