It seems as though Rey will go through some type of emotional and/or physical trauma in Episode VIII based on this interview.
Hopefully it’s both as it would make for nice character building but I hope they do something new if they’re going to physically injure her. Preferably something like her getting stabbed as that hasn’t happened to the other main protagonists yet.
EDIT:
When I say main protagonists I mean Luke and Anakin.
Really good news. Last question of the interview about love makes it clear that Finn and Rey’s friendship holds steadfast throughout ep. 8.
