The actor will discover that the unanswered questions can be found in his or her own interpretation and intuition. The playwright reveals the personality of a character in the lines and actions in the play. The character is not merely a set of lines, but a careful combination of events and circumstances that have molded the character's emotional, physical and spiritual depths which are revealed through the actor's actions. The director and actors must evaluate the lines to understand the objectives behind them. It is not enough to merely recite lines without knowing the playwright's intent.
True drama happens when an actor understands why the character is doing or saying something.
The behavior should matter to each character. Have the actors write the answers in detail. Encourage them to continue using the journal. The more they know about their characters' conflicts and inner emotions, the more likely they will be able to translate this to the stage. In fact, we are sure that if the actors do not do this, they will limit their effectiveness.
