It only doesn’t make sense when strictly compared to the comics, but it isn’t, imo, that much of a stretch to believe that Bail Organa and Padme couldn’t come up with a story of her survival that would keep them safe from the Emperor/Darth Vader.
According to Leia her birth mother died early in her life anyway, so it doesn’t bother me.
My ending goes like this:
-Birth of Twins/Darth Vader
-Bail/Kenobi/Yoda discuss next steps
-Ahsoka and Rex finish burying the Clones
-Yoda goes to Dagobah
-Bail and Padme go to Alderaan
-Kenobi goes to Tatooine
-Vader finds Ahsoka’s lightsaber
-Obi-Wan’s warning to the Jedi plays over the credits
I might consider an alternate ending, but I plan on pairing this with my own version of RotJ where we see Padme’s funeral while Leia’s talking about her mom being sad, pretty, and dying.
I’m touching it up, but since the last workprint of the ROTS: New Canon Cut seems to be the final version, this edit will probably only ever also get a polished workprint. Hopefully before the end of 2020, or as a January release.
