knew to do…kill of a hardened Jedi Knight. The difference here, though, is that she did not earn these skills. Rey’s ability to fight, fix machinery, or pilot a spaceship were never set-up or explained. She just already knew how to do all that stuff without any explanation to the audience as to how she knew to do it (Heck, she even knows how to swim in The Last Jedi despite having spent her entire life on a desert planet with no water). And when it comes to using The Force, the audience never sees her receive any training at all befor…
I can’t explain the swimming thing, that is a little weird. But, Rey spent her whole life on Jakuu having to defend herself, scavenge machinery of countless types, and I’m sure all the scavenging has given her a pretty good sense of how all the stuff works. It’s not explained outright in the movies, but it doesn’t need to be. It’s implied that she knows how to do these things because they were survival skills she needed on Jakuu. Her life before the start of A Force Awakens is a mystery, so how can we say she didn’t earn her abilities?
We don’t SEE Westley being trained by the Dread Pirate Roberts, we just take his word for it that he somehow has an immunity to the poison.
I’d like to point out that Finn ALSO uses the lightsaber without any training, but he doesn’t get any flack for that.
