Star Wars: The Force Awakens - 7 Big Questions About Rey That Need Answering
4. How Is She Linked To Other New Characters?
It’s a fair bet that all the new characters will be interacting with each other at some point, so beyond Finn and BB-8, what will Rey's relationship to the new cast be?
Outside of her mission, will she and Finn be friends, or is there a potential love story set to be told there? That’s not to suggest the character will be reduced to simply being a love interest, but it could be a developing arc if the writers and producers felt that a romantic subplot was necessary (which they often do).
In terms of BB-8, could he perhaps belong to Rey? It would make sense as to how he came to be on Jakku, and appears to be serving her and Finn in a similar way to R2-D2 and Luke et al in the original trilogy. Then there’s Poe Dameron - again their relationship could be friendly, it could be a more business-like, helping each other because they have to kinda deal, romantic, or maybe they're even siblings.
On the topic of siblings, one interesting theory posits that Kylo Ren and Rey will actually be brother and sister - and turning to the dark side, and she the light. That could be an interesting route to go down, but, like all of these guesses, it's really up in the air.
