With Ahsoka’s nod to the Mortis gods, I was thinking about that place, and how cool a location it was for the final battle in that “Duel of the Fates” script. It’s one of many things I wish weren’t dropped in the process of making Episode 9. I had a brain wave though about incorporating the Father/Son/Daughter mythology into the script that could have made for an interesting resolution, as well as addressing some common complaints about the ST.
Instead of dragging Palpatine’s corpse back, use Anakin as the final ‘boss’. The confrontation on Mortis ends with Anakin Skywalker appearing to Rey and Kylo. Anakin has become the ‘Father’, intent on bringing balance to the force, and to achieve this he needs a Son (Kylo) and a Daughter (Rey). Both have been ‘destined’ to fulfill these positions and have felt the weight of external forces pulling them throughout their lives. Rey defies prophecy, choosing to leave and help the galaxy directly rather than watch from a distance.
