I personally think mentioning both the texts AND Leia in such a tight space feels too forced, and like, wouldn’t the texts themselves show her how? It’s a neat idea to have Leia be involved, but she’s already very involved in Ben’s redemption as it is, she sacrifices herself to reach out to him, and with the added shot of the medal it’s also implied she had a hand in Ben’s “memory” of Han. I think is fine if the Force Heal is left as a personal moment between Rey and Kylo/Ben, and it gives the ancient knowledge Rey decided to preserve a moment to shine in this film.
+1
And with the new flashback dialogue that leaves the amount of time Leia trained with Luke up in the air, I think it is better for this just to be a character moment for Rey showing that she is taking the initiative to learn as a Jedi on her own as well.
