JACK. Algy’s elder brother! Then I have a brother after all. I knew I had a brother! I always said I had a brother! Cecily,—how could you have ever doubted that I had a brother? [Seizes hold of Algernon.] Dr. Chasuble, my unfortunate brother. Miss Prism, my unfortunate brother. Gwendolen, my unfortunate brother. Algy, you young scoundrel, you will have to treat me with more respect in the future. You have never behaved to me like a brother in all your life.
