She was reaching out to him before the vision though. He was there to listen and told her she wasn't alone. She got a glimpse of Ben Solo. When he removes the glove it was meant to symbolize Ben Solo, not Kylo, reaching out to her. And then she gets the vision of him turning. The force has guided her to a place she had already imagined in her dreams (the island, the tree). I think were meant to think she's taken Maz's advice to heart. Don't forget, she does offer the saber to Luke one final time and he refuses. This proves she was open to another possibility besides Ben being the only option.
I understand the symbolism, as it was also used throughout TFA. That line is a buffer for the following vision sequence that's completely disconnected with their previous interactions, where he's basically just saying dark, evil shit to pull her from the light. Which is why I keep stressing that it felt rushed.
When she said "neither are you", in the theater I literally said "wait.....
what?" That line felt completely unearned. It needed
much more development to get there.
I think you're
really reaching with the Maz advice, she was talking about harnessing the force, not "believe whatever you see through the force no matter what". She clearly used her advice in TFA to defeat Kylo Ren. But then in TLJ she seems to still be completely confused as to what it really is, hence her lessons with Luke and asking quite literally "but what is it?"
Yeah, and she can still offer the saber to Luke one last time before leaving, that's not something that needs to be connected with her 100% devotion to turning Kylo Ren.
My problem with the vision piece of writing is that literally nothing before would have mattered. As long as the Force shows you something, you are just all aboard with no second thoughts or doubts, in a direct and massive contradiction with the plot/characterization that came before. That's called removing agency.
Don't forget, Yoda teaches us in ESB that you can't predict the future because it's always in motion. But of course, Rey doesn't know this, just an aside.
Though I'm quite worried that JJ is going to "it was the right vision, just the wrong time" redeem Kylo. I'm very worried he's going the 100% redemption route.
