When Montag gets home, Mildred needs help because she has overdosed on sleeping pills. The two men, Harrison and the doctor, assist her by pumping out the poison from her stomach using a machine. This method is unusual because it has become a routine and mechanical process in their society. When Mildred awakens from her previous night's experience, she has no memory of what happened and shows no emotional reaction, treating it as a normal occurrence.
