I agree, Trevorrow’s script at least had a moment where Rey acknowledged how she would be a different Jedi, when she says to the Force ghosts, “Our master’s were wrong. I will not deny my anger and I will not reject my love.” I think generally that was on the right track. Jedi can’t shun their natural human emotions, they have to acknowledge their feelings and handle them appropriately.

I wish it could come from Rey, but the only ideas I can think of to make a more explicit way to get this concept across would be to either, a) Give Luke some kind of dialogue that is along those lines when he gives Rey her pep talk, or b) have one or more of the Force ghosts (Luke, Anakin, Ahsoka) say something to Rey along those lines. Maybe we could do both to reinforce that idea. I think it would definitely make sense for Luke to be the one to have came to this conclusion, and pass that truth onto Rey. We would just have to dig around for lines that would fit in well with this idea. There might be a lot more weight to this idea than them just telling her to “Rise, rise, rise” over and over again.
