Rian Johnson has recent opened up a little about Luke and Rey in VIII:

“I don’t want to skip ahead two years,” Johnson says. “I want to see the very next moment of what happens.” How Rey and Luke relate to each other is the key relationship in Episode VIII, and Johnson says “a large part of the movie” will be spent addressing why Luke’s there and what he’ll do next. Like Luke, Rey has been pulled into a bigger world by connecting with the Force, “but part of what’s she’s dealing with is the realization that she has this power and this gift,” Johnson adds. “She’s taking her first step to coming to terms with this thing inside her that she never knew was there and is just starting to reveal its potential.” - Rian Johnson

I think it’s going to be very interesting seeing one of our deal with the weirdness and suddenness of having such powers. Luke and Anakin are just okay with being Force Sensitive whereas Rey being confused about The Force could make for a nice inner journey for Rey. Also I wonder what her opinion on things in the Galaxy will be once she fully comes to terms with her Force Sensitivity and get’s some training. Kylo feels as though Force Sensitives should rule over those who are deaf to The Force; perhaps Rey will come to the same conclusion.
