Dialogue allows one theme to emerge through several speakers. The disputes and exchanges of people in the Fire can reveal responsibility and attitudes in addition to the reality of punishment.
The power of dialogue is that an abstract warning becomes a vivid scene. The audience encounters not only an outcome but also the arguments, regret, or denial of the speakers involved.
Interpretive principle: do not dismiss such exchanges as redundant threats. Ask who is speaking, to whom, and what new dimension the conversation introduces.
