Watching the movie again after a month away from it, I was struck by the scene where Jack, on the left, is peeling potatoes in the foreground while Ennis, naked and blurry in the background, is washing. The smoke from Jack's cigarette swirls in front of Ennis as Jack exhales forcefully, and the smoke obscures Ennis even more, just as we hear the sound of the water as Ennis swishes his washrag in it and uses it to wash "everything he can reach."
