A patient with a sensitive issue
This patient visited Yaakov at his home on the day when the physician brought Agapia home with him. When he saw Agapia in the room where Yaakov received patients, he said that he had a sensitive issue that he had to discuss with Yaakov in private, prompting the latter to send Agapia out. After meeting with the patient for a quarter hour or so, Yaakov left his home with Agapia, and headed to the docks. The patient presumably lives in Udyn. He appears in Chapter 12.
