@JJB Once you begin doing a TLJ novel edit, do you have any plans to make the way I see Rey’s TLJ arc clear so there wouldn’t be any misconceptions of it being a “Rey wants to find her place in all this” kind of thing?
In The Last Jedi, Rey refuses to accept the truth that her parents threw her away like garbage — even going as far as denying this when Kylo Ren taunts her during one of their conversations —, instead having lied to herself for the past several years of her life that they truly cared for her, that she was worth something to them, that she was abandoned for some important reason which would “show” that her parents cared for her, reinforcing this lie as a way of ensuring it would not perish — henceforth helping her feel happy and thus pushing away her feelings of self-worthlessness.
Rey, however, is unsure as to what that “importance” exactly is, and thus hopes that if she does find out she is important then it would “show” that her parents loved her and abandoned her to, say, hide her in an act of protection.
It is, for this reason, she, for so long, has wanted to find out as to who her parents were, hoping to infer as to what her “importance” is, only so she would use it to reinforce her lie — and why she hoped for Luke to show her this “importance,” hoping to use that importance to justify her parents abandoning her; however, when Luke refused, she goes into the mirror cave, hoping for it to show her parents to her — by seeing her parents, she would get to see who they exactly were, and, in turn, infer as to what her “importance” exactly is, judging their appearances.
In the throne room aboard the Supremacy, Kylo Ren manipulates her into admitting the truth — in that moment, she begins to refuse her lie, coming to terms with the truth that her parents had no true reason for abandoning her, that they hated her, seeing her as nothing but a worthless piece of junk.
(At this point, Rey admits her parents were “nobody,” in the sense they had no important reason to abandon her, instead discarding her as though she is completely worthless; she has “no place in this story” in the sense that, again, her parents did not abandon her because she was of some “importance” and loved her, they abandoned her because, to them, she is worthless.)
Because of this, she overcomes her “need” for her parents — the ones who birthed her —, and begins to move on from and stop caring for them altogether — hence why she seems happy and unaffected during the Battle of Crait in the film’s climax; now, with no other option, with Luke having rejected her, with Kylo Ren being the bad guy, with Han Solo now dead, with her parents having thrown her away like garbage, she attaches herself to the Resistance, relying on them for validation.
