Why would they rename the Resistance the Second Rebel Alliance? That’s pointless and confusing. As much as I would love to see a new generation of Jedi, Lucasfilm clearly doesn’t care for that. Why would Leia be killed offscreen?
They already renamed it and called them the Rebels in TLJ and a track on the soundtrack is “The Rebellion Is Reborn”… so blame Rian on that one. How else would you handle Leia? They said she would not be in the movie.
