That would fly better with casual audiences, for sure.
All I’m saying is that if Bethesda, a AAA game producer, can put this exact same storyline (referring to a “daughter” of an evil man as a “clone”) in a main questline for Starfield, it should work in Star Wars, too. Then again, one of optional questions you can ask her character is “You’re a clone of a man, how does that work?” And she more or less responds that she is genetically engineered. Gee, if only there was a canon Star Wars term for a genetically-engineered clone (looking at you, strand-cast).
But throwing all these made-up words everywhere, from strand-cast to dyad in the Force, would be too overwhelming. This is a tough nut to crack, that’s for sure.
EDIT: What about this - “Because he no longer needed you. After his return, and your escape, he saw his clones/creations as a threat to his power. You’re based off his template. You… are a Palpatine.” This way we dodge using the goofy word of “strand-cast” but give its exact definition in case it starts being used more regularly in the TV shows. I mean, heck, Dr. Pershing gives an entire presentation on them in all but name to the Senate in Mando season 3 (at least I think that’s where he was).
DZ, if you like your line that much I’d recommend putting it back up at the beginning - “I pushed you in the desert because I needed to see it… I needed you to see it… who you are. Darkness is in your blood, Rey…”
