Final answer:
Helen works for Madame as a regular designer and is well-compensated, while Tom had a past relationship with a man he knew when they were boys, which later developed into a professional one.
Step-by-step explanation:
Helen, the character in question, gets to work for Madame as a regular designer. The narrative indicates that Madame, a French woman, recognizes Helen's resolve to work hard, which perhaps includes saving money to pay someone back, referred to as Wynne. Madame negotiates a shrewd deal with Helen, but despite this, the pay is said to be excellent. As for how Tom knew the man he worked for, the text suggests that Tom and this man had a past relationship, described in the text as 'one of those rash friendships.' This man considered Tom a good worker and knew him from their younger days.
From the context provided, it is clear Helen is determined and focused on her work to achieve a certain goal, and that Tom's acquaintance or employer knew him from a young age. They had formed a friendship, which later in life seems to cause discomfort due to the man's 'familiar tone.' This could indicate a social gap that has developed between them over time.
