Rey… After 4 viewings I’m pretty sure that Rey is Han and Leia’s daughter. The way Han looks at her, the way he feels bad (or guilty?) when she says she “never thought there was this much green in the whole galaxy”, the way Leia hugs her instead of Chewie, the way Kylo Ren reacts to news of a girl helping BB-8 escape (“what girl?!”)… My theory is that Ben Solo had a younger sister and when he went bad they hid Rey to stop it from happening to her too.
This would make Kylo Ren and Rey equals. They are both the grandchildren of Darth Vader. Maybe the fact that one is good and one is bad is what’s meant by ‘balance to the force’.
Yeah had the same thought myself on my third viewing funny enough. The way han looks sort of guilty at that moment, although could be the guilt of an uncle an auntie who didn’t step in when the shit hit the fan.
