Just because she had a few books doesn't mean she intended to rebuild the Jedi order. Luke only gave her a very basic training and was still holding out on her, so she likely stole them to keep training on her own terms. If you steal a science book it doesn't mean you plan to train more science teachers, it just means you want to learn science. We know very, very few family histories of named Jedi, and half of them are Skywalkers or in some way connected to the family. Rey not being part of an established heritage nor having a direct tie to one would have broken up that dynasty. They would have still had to fight them, yes, but with vastly diminished resources, far fewer soldiers, and nearly no support. TLJ set up a scenario where it was possible, and indeed likely, that the Resistance would end up losing the war against the New Order. Yes, and again, that's something that was set up in TLJ and not anything Abrams did. So it actually strengthens my argument that TLJ tried to push things in a new direction with the setting, plot AND characters.
That goes counter to what Yoda says. That is all the girl needs. And Luke says, He is not the last Jedi.
We know most Jedi do not have family. Thus it can be assumed most of the Jedi that we see are not connected to anyone else. Since they never bring it up. But they did bring collecting kids from their families to join the order.
TROS writing was bad, I can't defend that.
TLJ did not set up Relyo. He hunted her abused her and tried to killer her. She was kissing Finn at the end of the TFA.
It is kind of funny that TLJ lovers say that TROS deleted everything that TLJ set up when it was TLJ deleting thing that TFA set up.
