I found an interesting picture that I believe will show Rey’s new look at the end of The Last Jedi. In this picture, Rey has a significant scar above her left eye, a cybernetic left arm, and a hardened look on her face. This could mean that when she faces Kylo Ren again, he will severely hurt her both physically and psychologically at the end of their rematch. This is kind of reminiscent of when Luke Skywalker was physically and spiritually wounded by Darth Vader in The Empire Strikes Back. If this is what happens to Rey at the end of the film, it could be an interestingly dark development in her character as well as a faithful homage to The Empire Strikes Back.
