Interesting interpretation, but is there anything that’s been said by the filmmakers that is along those lines?
I don’t think so. But this interpretation was around before TLJ’s release, and with TLJ I think the meta commentary has grown beyond these two characters, and audience expectation (or its subversion) now drives the story itself.
i am not convinced it drives the story (but do believe it is a factor, just not a driving one). audience expectation certainly drives our interpretations.
