It is true, of course, that novels establish well developed character relationships. However, drama is a more effective vehicle for building character relationships as it allows for non-verbal communication as well as dialogue. In Davis' No Sugar, the tension between the Millimurra family and the white' authorities is amplified by the uncomfortable way in which they move around each other. This is also seen when representatives of the white' establishments and culture exercise their authority' over the family. An example of this is when Mary gets whipped by Mr Neal. His movements are angry, vengeful and malevolent, whereas her movements are of pain, terror, yet still quietly defiant in the face of her adversity. Actions become much more effective when they are acted out, rather than described. In addition to that they appear less deliberate and more unconscious. For example when Jimmy challenges Neville for a train fare, he juts out his chin to defy all of Neville's racist attitudes presented. This described in a novel may be seen as deliberately mischievous however acted out, could be interpreted as an unconscious movement, and therefore supports Jimmy's whole persona as the trouble maker.
Movement can also be used to reinforce loving relationships.
