I don't know that I could have imagined a better follow-up so yes.
That was a requirement for you? We already knew that Kylo was lying to her in that scene because he also said "you have no part in this story."
But his follow-up in TROS about her parents choosing to be nobodies didn't negate what he told her in TLJ anyway.
He never did Palpatine's bidding out of obedience. His desire the entire film until he turned to the Light was to form the Dyad with Rey, destroy Palps and take the throne with her.
Wait you actually wanted the Saga to end with him destroying the Jedi and ruling the galaxy?
What?? The irony of your complaint is that he literally did accomplish Vader's greatest aspirations and that was bringing a girl back from the dead.
Professor Poe served his purpose well and even followed in the footsteps of previous Rebel leaders who started out all about the numbers (RO Mothma, ANH Leia) and then ended more concerned with the tragedy of lives lost (ROTJ Mothma, TLJ Leia.)
They're both Force ghosts now so yes they can.
Let go of your hate and embrace your one true self that you've only forgotten.
