He hasn’t even met her before she’s realized the truth of her parentage.
‘Dear child, you already know the truth. Whomever you’re waiting for on Jakku…they’re never coming back. The belonging you seek is not behind you, it is ahead.’
So glad that this minor mystery that she, by her actions, made peace with in TFA is now her central character flaw.
Of course you cut out an important part of that dialogue
Maz: “They’re never coming back. But there’s someone who still could.”
Rey: “Luke”
As Kylo notes in TLJ
“You can’t stop needing them. It’s your greatest weakness. Looking for them everywhere - in Han Solo, now in Skywalker.”
Her flaw is not the mystery, nor simply coming to terms with the fact that they’re never coming back. It’s relying on them or someone else in that role to guide her. The fact that they’re nobody isn’t devastating to her because it means she’ll never see them again, it’s because it means she doesn’t have an easily understood preordained story to follow (like being a Skywalker would), she has to figure one out for herself.
I’m with Tobar here.
