Since there are discussions amounting to Rey Palpatine edits in other threads, I thought I’d post this idea here.
I’d say this is a mischaracterization of things, at least at this point in the other thread. The other idea more or less amounts to Rey Chosen One. The perspective I’m trying to favor over there is that Rey is simply the second chosen one created by the Force since Palpatine cheated death, and just like usual Palpatine is trying to use what the Force intended to destroy him for his own gain. Only this time, he’s lying that Rey and the Skywalkers belong to him alone. In that way, I’d say we’re employing similar tactics. The reveal in the hangar is later revealed to be a lie, in my case by Luke, clarifying that they were created by the Force only to destroy Palpatine. Then we get a second twist of the truth in that Palpatine claims he always intended for her to kill him, so perhaps what he said wasn’t a lie all along. But, in all likelihood, it is one since she overcomes him without using the dark side, claiming herself a Jedi and Skywalker (earning the latter in every way except exact genetic makeup).
I like what you have listed right now because it cleverly uses the concept of visions in such a way that they are supposed to happen one way or another. This is something Star Wars has never truly explained except by saying “Always in motion is the future”. However, I agree with Raditz that your choice of location for revealing the lie of Rey Palpatine might not work exactly as I’m not sure what you’re trying to say there, either. And, ultimately, it might be frustrating to some viewers to have a potential explanation for her abnormally high levels of power, only to have not a single part of it be true, and with no other suggested alternative. This is one reason why the dyad might benefit an idea like yours, because it would let her tap into the power of the Skywalkers. You’d just have to specify that it started because of Snoke mindlinking them, so Rey can still be a complete nobody and not be fated to be linked to an important family like the Skywalkers.
All that being said, the idea we have on the other thread can never be Rey Nobody in essence, because Rey, despite being made by nobody (the Force itself) and raised as a nobody by nobodies, is still somebody of extreme importance in the grand scheme of things. But I think removing the direct lineage to Palpatine makes things more palatable, and for those who preferred a direct link to him for whatever reason, they can still imagine that Palpatine did maybe have a hand in how the Force designed them, despite the conclusion of everything pointing to the contrary (ya know, the part where Palpatine finally admits she’s nothing but a scavenger girl).
