"All's right!—all's right!" he cried. "It's a mere rehearsal of Much Ado about Nothing. Ladies, keep off, or I shall wax dangerous."
Chapter 20 · Edward Rochester
Context
Rochester emerges from the third floor holding a candle and finds the house guests gathered in panic in the gallery. He dismisses their alarm, claiming a servant had a nightmare, and compares the commotion to Shakespeare's comedy.
Analysis
Rochester's literary allusion to 'Much Ado About Nothing' is bitterly ironic—he names a comedy about misunderstanding and deception while actively deceiving his guests about a violent attack. The phrase 'wax dangerous' uses an oddly archaic verb that sounds almost theatrical, as if he is performing the role of calm host rather than genuinely being calm; his language choice reveals the artificiality of the performance.
Essay Tip
Support a thesis that Rochester uses cultural authority (literary references, command of tone) to control the narrative and suppress others' perception of reality—his allusion doesn't clarify but obscures the truth.
