Yeah, you’re right, Hal.
I do disagree though that Rey explicitly confirming where she learned it from in the scene is useless. What we currently have in the texts is definitely something a more casual viewer could gloss over or be unsure of what exactly it’s referring to. When Rey refers to the texts in the later scene, it ensures that everybody has made the connection from earlier in the film.
I think it ultimately just comes down to how important you think explaining the power to the audience is. Personally I think not very (I wouldn’t mind if you blinked and missed it), but for this edit it’s of course up to Hal to decide.
