The only thing I’m doing is to remove Finn’s line about R2 backing up his memory, so that it isn’t completely undermined before it even happens.
I like the idea from DOTF for R2 to tell 3PO about everything he had forgotten, though. But we don’t have the resources to cobble anything satisfactory to imitate it.
I think we would need to implement it as some kind of quick sequence of the Saga flashbacks. Though, I dunno if that’s doable.
