To get rid of the issue with the force revival, would it sit better with anyone if Rey had never used it in the film, and then the power is used just by Kylo at the end to save her? This ties in with the idea that it is the type of manipulative “unnatural” power that only a Sith can have, and that Kylo uses the power he attained by doing horrific acts for some good in his final moments, somewhat redeeming himself.
I am always a fan of actually teasing and building to concepts that lead to actions, so to do so, I would have Snoke tease Kylo with this ability. In earlier posts, I have brought up how Snoke’s audio language could be changed and he could get new dialogue in the form of subtitles to tease the return of the Emperor. On top of that, you can also have Snoke tease Kylo once or twice about the ability of the dark force to reverse death.
Maybe you could tie this with Kylo’s longing towards the Vader mask, and portray early Kylo as wanting to revive his grandfather who in his own mind perverted by the Sith way he thinks could be a true father figure to him. Again, this idea could be pushed by a subtitled Snoke. This also recontextualizes “let the past die” to be a more literal theme for Kylo as he goes disenchanted with his Sith journey.
Anyways, the ability could be teased by Snoke maybe 2 times in Force Awakens, once in Last Jedi (before Kylo kills him), and then Palpy requoting his line from Episode 3 will feel like a continuation of this storyline. Then at the end, you get the payoff of Kylo having this ability that has been talked about since Ep3 of the saga, and he uses it to save Rey in his final moments.
Anybody like this idea? I’m just throwing stuff out there. I think it would be able to be pulled off without being too “fanedit-y” and cement a lot of the themes of Kylo Ren’s journey.
