Well you should probably learn the difference between character and characterization before you try and convince people that a bunch of random, convenient traits, were essential to understanding who Rey is.
Oh fuck off. You should try thinking a little harder. As I said there is nothing convenient about her understanding of multiple languages. What it does is show that Rey is someone who’s spent a lot of time learning about a lot of different things. But you can’t seem to understand that so I don’t know why I keep trying to explain.
