Replying back. What you just said about Rey wanting Han/Father Figure back, and Grumpy Old Man Luke turning out to be her Father. It reminds me of Luke wanted Obi-Wan/Father Figure back, and Grumpy Old Man Vader turned out to be his Father. Really the parallels between Anakin/Luke/Obi-Wan, and Luke/Rey/Han are there. Plus RJ said Rey&Kylo are light&dark, well look at what Luke&Leia is wearing in TLJ. Luke&Leia's light&dark clothes matches Rey&Kylo's light&dark clothes.
Ding ding! I think we have a winner!
