Why does Rey have a memory of crying watching a ship leave Jakku when she was little? Either the next film ignores this completely or there’s more to tell about her family.
Clinging to the hope someone is coming back to get you after so many years is desperation. Clinging to that hope when you know for certain that someone is actually dead is delusional. I don’t think Rey was delusional.
I still believe she goes back to Jakku in epX, finds out Leia/Han hid her there after Ben turned. That’s why Ben asked “what girl”. Maz helped them hide her there, which is why she is intrigued by her. Kylo has been lying to Rey because he knew she would never join her if she knew he murdered their father in front of her.
Or, she’s nobody and this is the end of the Star Wars saga. As Kennedy said, the main saga has been and always will be the story of the Skywalker family. If Rey isn’t a Skywalker, there is no plausible redemption for Ben that continues the line.
