A Rey parentage reveal is needed at some point, after what was set up.
As I said for “last Jedi living in nowhere”, just because it was thrust upon by TFA it does not mean it is not a rehash.
I see TFA and the ST as less a direct sequel and more a continuation further down the line with a new generation.
Well regardless of how you see it, the truth is that TFA is more of a soft remake than sequel.
