Even if Rey isn’t a Skywalker, she is essentially the heir to that role and the bearer of their legacy. I believe it’s fitting that the end of the Skywalker story would focus on a non-Skywalker who will carry and pass on the torch after they’re gone.
If you want to talk about a heir, technically it would be Kylo aka Ben Solo who should inherit Anakin’s lightsaber and the Millennium Falcon as birthrights, being the only current surviving member of that family.
Obviously because of his history that will never be allowed to happen but he still has far more right to that legacy than Rey ever will who is essentially a random with a ridiculous affinity for the force…
Yep, that’s literally the point of her and Kylo’s characters. You’re so close, think about it a bit more and maybe you’ll understand the filmmakers’ intention and what I meant by “heir.”
Among possible responses, this was probably the most Waltersobchakeit.
