Lady Malcolm's Servants' Ball, an event she puts on so that the servants have a day of gaiety and levity. Costumes are required. Of course, all of the bohemians take it as an opportunity to dress up in wild outfits, flirt, get drunk, and generally not have the sort of wholesome fun Lady Malcolm intended.
William Way finds this kind of confusing but fails to process it.
"Do you wanna head back inside?"
"Without the bird, I think?"
Chu Chu has never been to a fancy party before and is pretty sure that William is wrong about attending them.
The balcony is where the wealthiest and best-bred people in London come to see and be seen. You see a glittering insect, an Arabian prince, a fairy, a lioness– all dripping with gems the people on the floor couldn’t begin to afford. Masks cover everyone’s faces: could you be speaking with a millionaire or a duke?
William Way climbs up the stairs like he belongs there.
Violet does not particularly want the possible scrutiny of fancy people, but, given she's dared herself to be here, acting like she feels that way will grab more attention than not.
Oh dear. "She disapproves of his deadly extracurriculars, I think," Violet whispers in Chu Chu's ear.
"I am the daughter of one of the finest families in England. You are a guttersnipe with pretensions."
"CHU CHU," William says, ignoring her, "back me up here, surely anyone would want an award-winning performance of the latest modernist music, showing off their exquisite taste and up-to-the-minute sense of fashion--"
"YOU CAN'T DANCE TO MACHINE SOUNDS. IF I WANTED MACHINE SOUNDS I WOULD HAVE HIRED A TRACTOR MYSELF."
"Not an actual steam engine...?" She hates this but she also loves this. These people are hilarious.
