I really don’t see a need to assign Palpatine any AI lines, at least for the Rey Palpatine version. I find myself as the naysayer at the moment about that aspect.
I agree that Rey’s parents still do need to be set up, but that dialogue for him sounds perfect for the Rey Nobody version of this.
I like the idea of Jannah attributing her company’s own awakening to Finn’s, like a ripple effect. Might just be a touch weird she does not react to him identifying himself or that she doesn’t recognize him on sight.
