2. The estrella Wars saga is also a story of redemption through familial love. It'd make más sense for Kylo Ren/Ben Solo to be redeemed por his sister than a misceláneo amor interest.
3. Her outfit and hairstyle in The Force Awakens are reminiscent of Leia. Though such things are obviously not genetic, they are often used in films and TV series as a means of connecting characters and suggesting a relation.
4. Her strength in the Force made most people assume that she'd belong to the most well-known Force-sensitive family in the series. Even though tying her to Palpatine does explain her strength, it'd be even better to make her be related to at least four different known Force-sensitive characters rather than just one.
5. When we are shown Rey's inicial in Jakku, we see that she has an old doll dressed as Rebellion pilot. This would possibly suggest that she came from a family who were members of the Rebellion.
6. Her instant ability to fly the halcón could be explained por innate piloting talent, as shared por Luke and Anakin, o even por being taught to fly the ship as a child por Han. Similarly, her ability to understand Shyriiwook could be explained por learning to communicate with Chewbacca as a child.
7. She and Han are often finishing each other's sentences when they first meet. This is often used as a means of suggesting a connection between characters.
8. Han's reaction when she claims not to have known there was so much green in the whole galaxy looks as if he's thinking, "what have we done to you, my child?"
9. Han later gives her a weapon to defend herself. The scene is far más poignant and emotional than the equivalent scene of him giving a weapon to Finn. It's almost like a scene of him enabling his daughter to protect herself.
10. As Kylo Ren pointed out, Han was the first character Rey looked to for a father figure. It'd be ironic if he actually did turn out to truly be her father.
11. Maz tells Rey that the belonging (her family) that she seeks is not behind her but before her. She later meets Leia and Luke.
12. At the end of The Force Awakens, it'd make más sense for a newly widowed Leia to hug her long lost daughter than for her to hug a stranger.
13. It'd also make más sense for it to be Luke's own niece, and the sister of the last student whom he failed, to be the one to bring him back out of his exile, rather than some misceláneo Force-sensitive stranger.
14. After The Force Awakens, Rey effectively inherits the Millennium Falcon. That would be más fitting for Han's long lost daughter than for someone with no connection to him.
15. It'd make más sense for Anakin's light-saber to be found por Rey and to later be summoned por her if she were descended from him. It's another case of inheritance.
16. During Rey's flashback vision in The Force Awakens, the lights of the ship seen flying away resemble those of the Falcon. When the scene is repeated in The Rise of Skywalker, this has been altered. It was obviously a hint that her family were on that ship, leaving her, and it was later retconned to prevent Rey and Kylo Ren from being related.
17. It'd make más sense for Rey to have been dreaming of Luke's whereabouts for years if she was related to him. If it were only the strength of the Force there calling to her, the same should have happened to other Force-sensitive individuals too.
18. Luke even compares Rey and Kylo Ren, saying that he'd felt the same raw strength in both. This would fit them being siblings.
19. Both Kylo Ren and Snoke claimed that the truth about her parentage would lead her to the Dark Side. This could be based on the betrayal of learning that the allies whom she admires and loves were actually the same ones who abandoned her.
20. It'd be another example of the estrella Wars series sinking a ship por revealing that the characters are actually siblings, though in this case with más foreshadowing.
