Rey and Kylo(Ben) have the same force connection as Luke and Leia.
Rey and Ben are same age.
To say that she was just traded off would fit in with the Luke and Leia separation type thing. To protect.
It would make sense to hide her- like Luke.
I don’t believe that Rey’s parents were degenerate junk dealers. Rather people posed as such to say goodbye to their baby girl to keep safe… like dropping off luke on tatooine- she was sacrificed to save her.
she could’ve been put with other people to initially keep true parent’s identity (Han, Leia) secret.
twins- they are like luke/leia
