I just discovered something mind-blowing regarding The Rise of Skywalker! They released some footage of Kylo Ren confronting Darth Sidious, which is in the following link. In that footage, we learned that Sidious truly IS Supreme Leader Snoke! To be more specific, Snoke was Sidious’s puppet and mouthpiece. In addition, Sidious had been communicating with Kylo Ren through the remains of Darth Vader’s helmet. Throughout the footage, as he was talking to Kylo Ren, Sidious’s voice changed between his own and those of Snoke and Vader, saying, “I have been every voice you have ever heard inside your head.” This shows that it was Darth Sidious the entire time who manipulated Ben Solo into turning to the dark side. It appears that Sidious has been grooming Kylo Ren to be his new Sith apprentice from the shadows, using Snoke and Vader’s helmet as proxies. After Vader “killed” him, Sidious saw him as a failed apprentice so he turned his attention to Ben Solo, who had just as much potential in the Force as Vader. With Vader’s helmet, Sidious was able to tug on Kylo Ren’s sentiment towards his grandfather. Through Snoke, Sidious was able to do test trials with Kylo Ren, teaching him basic dark side knowledge before he was ready to fully commit to him as his Sith apprentice. Also, even if something were to happen to Snoke, Sidious himself would remain hidden until he was ready to reveal himself. Now, Kylo Ren has proven he has something his grandfather lacked: the ability to kill and overthrow the master and usurp his power, which is the prime principle behind the Rule of Two. With this in mind, Sidious wanted Kylo Ren to kill Snoke to prove that he is capable of completing the Rule of Two. Afterwards, Sidious would leave Kylo Ren to his own devices to see what he would do once he gained real power. Clearly, Sidious liked what Kylo Ren became and has called to him through the dark side to officially become his new Sith apprentice. Just thinking of the lengths Sidious went through to orchestrate the formation of the First Order and discreetly grooming Kylo Ren into his new apprentice makes my mind blow! Up until now, we have only seen the puppets, but we will soon see the puppeteer. With these new revelations, I look forward to see the movie in its entirety to see what plans Sidious has for his new apprentice.
