I love the idea of mentioning the jedi texts AND Leia mentoring her, if possible. Gives much more meaning to both she taking the books from Luke and her healing Ben some time later.
Alas, at this point, this healing power is not even that special. I mean, Grogu can do it as well, so it’s kinda of a random force ability that some force users are going to get and develop, and some will just not.
