- When he was younger he was given electric shock therapy that leaves him permanently brain damaged. His efforts to appease the ever-complaining Davies may be seen as an attempt to reach out to others. He desperately seeks a connection in the wrong place and with the wrong people. His main obstacle is his inability to communicate. He is misunderstood by his closest relative, his brother, and thus is completely isolated in his existence. His good-natured attitude makes him vulnerable to exploitation. His dialogue is sparse and often a direct response to something Mick or Davies has said. Aston has dreams of building a shed. The shed to him may represent all the things his life lacks: accomplishment and structure. The shed represents hope for the future.
- Davies manufactures the story of his life, lying or sidestepping some details to avoid telling the whole truth about himself. A non-sequitur. He adjusts aspects of the story of his life according to the people he is trying to impress, influence, or manipulate. As Billington points out, "When Mick suggests that Davies might have been in the services — and even the colonies, Davies retorts: 'I was over there. I was one of the first over there.' He defines himself according to momentary imperatives and other people's suggestions" (122).
- At times violent and ill-tempered, Mick is ambitious. He talks above Davies' ability to comprehend him. His increasing dissatisfaction with Davies leads to a rapprochement with his brother, Aston; though he appears to have distanced himself from Aston prior to the opening of the play, by the end, they exchange a few words and a faint smile. Early in the play, when he first encounters him, Mick attacks Davies, taking him for an intruder in his brother Aston's abode: an attic room of a run-down house which Mick looks after and in which he enables his brother to live. At first, he is aggressive toward Davies. Later, it may be that by suggesting that Davies could be "caretaker" of both his house and his brother, Mick is attempting to shift responsibility from himself onto Davies, who hardly seems a viable candidate for such tasks. The disparities between the loftiness of Mick's "dreams" and needs for immediate results and the mundane realities of Davies's neediness and shifty non-committal nature creates much of the absurdity of the play.
