Mrs. Glister guesses that Maria is pregnant and demands to know who the father is. Maria refuses to tell. Gerardine enters, still disguised as a porter. He says that he has a letter for Doctor Glister. Mrs. Glister takes the letter (a fake) and reads it. The letter appears to have been written by Glister's mistress. The "mistress" informs Glister that she has given birth to his son. Mrs. Glister falls into a jealous rage. She screams at Maria and says she will go to the law to get revenge on Glister.
