Personally, it’s very inviting and pertinent for me to project myself onto Luke in that scene. With what Yoda would be referring to in my subjective dreamscape, my response to Yoda’s question wouldn’t be that I hadn’t read the texts before.
I do wonder what a cut of TFA and TLJ would be like that strips all (subjectively) ~’unearnest’ humor. Part of what made the original SW great was it’s sincerity.
