1. Scrap that whole luke and kylo thing. I would try and explore the Kylo Evil root more: Perhaps Luke was trying to hide that his father was Vader to his student, and that being han’s son he was being trained especially harsh, and kylo’s natural strong connection to the dark side of the force is corrupted by his emotions. Being connected to the dark side is not inherently a bad thing. As kyle katarn said there is no good or evil in the force, only how you use it. Troubled by his emotions, perhaps he had a vision of what is to come, that he foresaw one day he would kill (SPOILER) his own father.
Thus he was afraid, but didn’t dare to tell Luke about it, because he is scared that Luke would see him as a monster. A kin-killer. Little did he know that Luke’s father was the Dark Lord who tried to kill his son, in a way similar to his situation. When young Kylo approached Luke and asked him for advice, Luke simply told him the generic jedi stuff, controlling your emotions and all. He nurtured doubts about luke’s teachings, all the while feeling powerless in the flow of fate. He feel destined that he would kill his father. He wants more power, power to change the future. Like vader. Vader who tipped the fate of the universe, who brought balance to the galaxy.
Here’s when snoke comes in, who tempted him with power, to outperform all other students of Luke. To make his father PROUD, to SAVE his father, to CHANGE bis fate. All he needs to do, is to retrieve the sacred text from the temple, and steal them for snoke. He got drawn to the sacred text, and Luke was there to stop him, but as Kylo stood there at the entrance, Luke sensed nothing but SNOKE standing there. Clouded by Snoke’s decption and power, Luke drew his lightsaber thinking to defrat this unknown sith. Little did he know kylo was the one standing there, horrified, as his master drew his saber on him. Thinking that his master is trying to kill him for stealing and betraying his trust, as well as finding out his dark side and his vision, Kylo was forced to react, all the while screaming at Luke trying to make him stop, but Luke being the grandmaster bested him with little to no effort. As Luke went for the finishing blow, his sabrr seared across kylo’s face, perhaps blinding his right eye, Luke saw that it was his student. Horrified and shocked, Kylo took the chance and ran. And never came back. Now that leaves you wondering. What is in the sacred text? Is kylo destined to kill his father? Or does everyone, after all have a CHOICE?
It makes Kylo killing han scene a much deeper one. Kylo was simply fulfillimg his destiny. His vision he foresaw so long ago. He is sorry, but he knew killing Han would simply be a step closer to what he had seen. Did He stabbed him by choice? Or by fate? Was he in control, or was it simply kylo bowing down to his destiny?
2. Carrie’s flying in space was because of Kylo. Being force sensitive doesnt give you an invisible space suit. Nope. Not even when you are dying. At least not without training. As much as I love carrie fisher, this is just way out FAR. Make Kylo be the one who saved her. Perhaps he was still good in the inside. Perhaps he regretted killing his father, and he saved her mother by force lifting her to safety. This also shows Kylo’s POWER beyond the blaster scene in ep7. His demonstration of control of the force while flying in a star fighter, force lifting at extreme ranges and his concentration.
3. Snoke should not have died. Excellent actor and potential, wasted opportunity. I know that they don’t want another sidious, or some generic evil guy, but killing him off like that is just dumb and lazy plot writing. Snoke being so mighty and powerful should have known kylo’s intention. I would have added a scene where Kylo force leapt at snoke in the last second, attacking snoke with his lightsaber, while Snoke laughs maniacally while blocking it with the force (inspired by Vitiate cutscene in swtor the game against arcann) imagine how powerful he must be, to block lightsaber hits with sheer power in the force and hand. Then as Kylo was being defeated by Snoke, rey backstabbed him with her lightsaber, in which Snoke laughed and slowly faded away, his laugh replaced by that of KYLO. Heres my twist: snoke was the projection of KYLO. His connection to the dark side of the force is so strong, that he unconsciously projected this inner dark self, an alter ego. A projection of his dark side’s self. It explains why Luke sensed such darkness in him, and why he saw snoke in 1. Above. It explains the mysterious appearance of this master of the dark, since he exists as long as kylo exist. He has long struggled, Kylo being the struggled “apprentice” while Snoke being the “master”. But in reality, Kylo is the true “master” while Snoke was merely his evil consciousness talking to him and representing the face of the first order unbeknownst to hux and the others. As rey killed snoke, she in a way had cleared Kylo’s doubts and fears. He is no longer afraid. He KNOWS what he is now. Snoke is no longer a separate entity. He’s now a part of kylo. His consciousness corroded. He became the vessel of the dark side. A horrifying abomination. This also echos Rey’s scene in the dark hole, where she saw reflections of herself. She was trying to find, to search her parents and what she’s facing and struggling, but she found no answers. In fact, the hole showed her exactly what she was looking for. Her parents being nobody, and that she was facing herself as kylo is facing himself.
