the medical attaché is still watching

A whole scene that is one sentence, and the sentence is a clock reading plus the word "still." The lethality is conveyed by nothing but duration — no content, no description of what's on the screen, just the fact that hours in, he has not stopped. The Entertainment's power is rendered as pure stasis: the most eventful thing that can be said about a man is that he is still watching, that the watching has become the entirety of what he is doing and, we will learn, the entirety of what he will ever do again.
