I shot you a PM, Hal.
I tried “You’re just a clone” with my Adam Driver model a while back. Due to the fact that it’s based on his TED talk, it doesn’t sound good quality-wise. Adam’s audio book doesn’t sound much like how Kylo speaks in the intro scene, either.
Plus, I agree with what somebody else said about this particular line. Without Palpy’s response “More than a clone, less than a man”, it would confuse the audience into thinking this dude is literally just a clone and not the actual Palpatine in a clone body.
I think poppasketti’s shot of the Palpatine clones in the vat says it all.
