Lucy’s monologue came from a couple different places: 

A) A conversation with an animation showrunner who said that, when he interviews a new artist, he pays close attention to how they interact with the other people in the room: the assistants, the coordinator, the secretary. Almost everyone will try to suck up to the boss, but you can tell a lot about a person based on how they interact with people below them in the pecking order. (Granted, Hyde doesn’t look down on Elsie and Patrin, at least not consciously, but the fact that he managed to reign in his emotional outburst the second Lucy arrived is . . . definitely not a good look for him.) 

B) My mom’s experience dealing with sexism/racism in the workplace--the old “work twice as hard to get half as much” situation. The idea that a young  kid like Hyde could spend a couple years goofing off around the city and believe that he was somehow on the same level as a woman who spent her entire life painstakingly carving out a space for herself and other women in a male-dominated world? Comedy.
