What must novel dialogue . . . really be and do? It must be pointed, intentional, relevant. It must crystallize situation. It must express character. It must advance plot. During dialogue, the characters confront one another. The confrontation is in itself an occasion. Each one of these occasions, throughout the novel, is unique.
