The Force Awakens and The Last Jedi.
The end result was quite strong, with powerful sequences featuring Leia that greatly influenced the The Last Jedi, she almost believes that her son is lost forever, until Luke leaves one final message to her that no one is ever really gone, inspiring hope in her once again.
While Kylo and Rey mostly battled to a standstill, Kylo's experience and training eventually start to give him the upper hand. As Rey continues to lose herself in the anger that is her lineage, Kylo fights with a sense of calm, ultimately leading towards his own victory. Leia sensed the battle was about to be lost and knows that to reach out to her son one last time, she needs to sacrifice her life in the process. Leia used every ounce of force energy she had left to simply get to her son with one final word, his name. A scene that is very Chris Terrio in nature, hearing his mother say his true name as her life expires was enough to completely stun Kylo Ren. Not too unlike the Martha moment of Leia snapped Kylo Ren back to Ben Solo as her final act before death.
Eventually, it leads to a surprise cameo from Harrison Ford's Han Solo, greatly influenced by Leia's actions. The scene was powerful and emotional. Knowing Carrie Fisher has ed and every scene of hers in Star Wars: The Rise of Skywalker was archive footage from previous movies, a tip of the hat must be given to J.J. Abrams for figuring out a way to make Fisher's final word in The Rise of Skywalker be the most important one to the film.
Kylo Ren was almost immediately turned back into Ben Solo with the final words of his mother. Rey, still in pure anger, stabs him, Leia's legacy as a princess, general and Jedi is stronger than ever as the Skywalker saga comes to a close with Star Wars: The Rise of Skywalker.
