Mr. Benedict’s predictions of “the thing to come” are proven correct as Mr. Curtain reveals his plans for the Improvement. His joke about “open minds” also shows that he finds humor in undermining free will. He uses the phrase with double meaning––in the traditional sense, a student with an open mind is a good listener and ready to learn, but Mr. Curtain also forcibly opens minds to encode his transmitted messages. His laughter at this joke marks a twisted version of his brother’s enjoyment of wordplay, indicating yet another way the brothers are at once similar and different.
