The voice lists the three instances listed above where the woman has appeared to him in the past. When he reaches the third one the camera cuts to the woman's face, "reduced as far as possible to eyes and a mouth", which mouths silently along with the voice, "...clouds...but the clouds...of the sky..." The man then realises there is a fourth case, but not really a fourth "" because so much of the time, by far the greatest amount of the time, nothing happens, the woman never even appears.
