There's typically some point in a TV show or movie, where there's a scene that appears to deliberately go out of its way to make a feature of its obvious discontinuity or incongruity by obsessively lingering on some apparently trivial element and/or motif, only later to be validated as a crucial factor leading to the “reveal” or “twist” in the narrative resolution much, much, later on. Such moments have a technical term of art know as the: “It seemed extraneous at the time” as identified by Dr. Raoul Dukeson. It is a device often over-employed by the late director M. Night Shyamalan whose career died pre-post-prematurely.
