When we describe a situation or a person’s behavior as “dramatic,” we usually mean that it is intense, exciting (or excited), striking, or vivid. The works of drama that we study in a classroom share those elements. For example, if you are watching a play in a theatre, feelings of tension and anticipation often arise because you are wondering what will happen between the characters on stage. Will they shoot each other? Will they finally confess their undying love for one another? When you are reading a play, you may have similar questions. Will Oedipus figure out that he was the one who caused the plague by killing his father and sleeping with his mother? Will Hamlet successfully avenge his father’s murder?

This sentence just shows the restatement of the given idea. Restatement is saying something in a different way in which the author uses it here for the word "resigning".
