Dwayne is a novelty items designer. He is seen n the suite R of the Mansion wanting to kill himself but he fails even in this as the gun he uses is actually a flag gun. Bernard Bernoulli gives him a letter sent to Red Edison to lift his spirits. Thinking that his talents are accepted, he runs away in enthousiasm, presumably meeting another disappointment.

Dwayne seems to be a descendant of John Hancock.
