So Rey currently claims with Finn that she saw both Kylo and herself on the Sith throne in her vision. This is wrong. Only Rey is seen on the throne in both the theatrical release and Ascendant. And the vision in Ascendant, in my interpretation, represents the two dark paths she could end up on (either with Kylo or the Sith).
Luckily this can be corrected by simply removing Finn’s line: “Ren?”
It’s obviously a Force vision Rey had off-screen we didn’t see.
