Just remember that, if you want to take the version(s) you want to construct the 'canon' you are happy with, then everyone else who takes a similar approach can do the same.
I.e. some people will take, for example, Alto, gender identity issues and all; others will see Ranka as a far more mature and reliable person; still others will see both the good and bad sides of Sheryl. And they aren't wrong to do that.
That's not my own approach though, so I'll leave you guys and gals to it.
