Question- How does Lucilius, a minor character in the play, help advance the plot in the passage?
(Okay first off, you gotta specify what play or people won't know what you're talking about)
Answer- Lucillius is protective of Cassius so he diminishes the seriousness of the conflict. Lucillius tells Brutus that Cassius intends to attack Brutus, increasing the tension and conflict.
