I like the idea of removing Leia knowing Rey’s heritage, given that there’s no way she would know unless it’s another one of her weird “Somehow I’ve always known” moments which just raises more questions about why she did absolutely nothing with this information.
Exactly! If Leia knew Palpatine had offspring it’s hard to believe it wouldn’t raise a flag.
"Hey… wait a minute, It all makes sense now! Palpatine’s behind it all!”
