This moment is essential into knowing what the outcome of the play is about. It is a gateway for the characters to create a doubt within their working space. This doubt that plagues the office represents the downfall of the job and the goal they are all working towards. The overall construction of this moment reveals a sense of unease and creates a feeling of missing something and never knowing the certainty of things, which ultimately create an experience of uncertainty in what the play is trying to convey throughout the play and especially at the end of the play.
