Going on a tangent, it seems like there has been more speculation recently what we might find out about Rey’s origins in IX, because apparently there is more to that story in the film.
It seems the theories have been ranging from Kerri Russell’s character being her mom, stuff related to Palpatine, a lot of “Rey is a clone” theories for some odd reason, and I have a friend that is still adamant that Rey is a Skywalker.
I think we tend to blow the little hints we get about the movie out of proportion, so I have what I think is a modest theory:
Rey meets someone (maybe Kerri Russell’s character) who might know where her parents are. Maybe they’re not dead like Kylo thought. Maybe Zorri is the one who gave them a ride off Jakku, since people keep comparing her ship in the trailer to the one we see leave Jakku in Rey’s forceback vision. So, Rey ends up having a choice to either continue her mission with the Resistance, or find the parents she has wanted back all these years. But in the end, she lets that desire go and chooses to her new found family, Poe, Finn, Rose, etc.
Knowing my luck it will probably be some big reveal, but I honestly would be happy with something rather modest.
