I have chosen a particularly meaty scene to try and explore what the subtext might have been. This is only one possible look, of course; that's one of the great things about subtext. Because it's implicit and not explicit, it lends itself to different interpretations, no single one objectively correct (especially if you're like me and don't mind ignoring authorial intent). One of the things I like in this scene is that besides the subtext hiding behind the main focus of the scene, there is also a character without any lines at all who conveys a remarkable amount of information in a single shot.
(I do actually think some meta about subtext and the like would be very interesting, though.)
