This shows the will of the Inspector and his determination as he walks straight out of the room with no hesistation or pausing. This also asserts his confidence that he has left the Birling's with guilt and regret about their actions and therefore fulfilled his duty to spread the socialist message. Furthermore, the list of three at the end of this stage direction allows for the audience to see that the Inspector has been able to reach every single person in the room despite their unwillingness at first to accept responsibility. This shows that the Inspector can find the truth about anyone and encourages the audience to adapt socialist views similar to that of the Inspector as they do not wish to become as guilty and shameful as the Birlings are at the end of the play.
