“She was quick to learn in our training. But Leia was vigilant of the inner darkness she could awaken, and chose to serve the people of the galaxy instead. She surrendered her saber to me, and said it would be picked up again by someone with the spirit to face that darkness.”

The implication here is that Leia chose to become a Jedi sentinel. This would finally explain why the hell Rey has a yellow lightsaber at the end of the movie: she’s literally continuing Leia’s Jedi path exactly where it left off as a Jedi sentinel herself. I’d be down to literally state that Leia chose to become a Jedi sentinel, but that risks alienating people who don’t know exactly what that entails. It might also conflict with canon content which states that Leia did give up her Jedi path entirely.

I made a slight modification to your other line:

“Luke saw the same fate in me. But only together can we resist it.”

EDIT: Here’s how that more canon-breaking/casual alienating one might sound - "She was quick to learn in our training. But Leia was vigilant of the inner darkness she could awaken, and chose to serve the people as a Jedi Sentinel. She surrendered her saber to me, and said it would be picked up again by someone with the spirit to face that darkness.”
