I believe I do have a timeline of events that you might find elucidative.
The Nightingale family are celebrating Christmas with a family friend, Monty James.
His son, Oswald, and daughter, Gally, both protest that he should wear the hat. Even his wife, Lettie, points out that Mr. James is wearing the hat that he won from his own cracker. Patrick is unmoved and does not wear his hat.
Gally blames the rip on the large size of Oswald’s head, but suggests that Oswald should take their father’s unused hat. Patrick refutes the idea, saying that Oswald should have taken better care of his hat.
Seeing an opportunity to lighten the mood, Mr. James seizes Patrick’s hat and rips it. The family laughs as Patrick then rips Mr. James’ hat and Gally rips her mother’s one.
Patrick describes this round of hat ripping as “fun in its proper place”.
As the laughter dies down, Gally tells Oswald to let their dog, Toby, out.
At the end of the meal, Patrick reveals to the children that Mr. James is known for his ghost stories, and that he has kindly consented to tell them one now.
Her parents are hesitant, but are somewhat reassured when Gally tells them that Susanna has recently married a Captain Noone and that he will be travelling with them.
Gally’s brother, Newt, has been on the sidelines of the discussion. When their parents withdraw to discuss the matter, Newt asks Gally more questions about Susanna’s supposed husband.
Newt deduces that Captain Noone is a ruse. He tells Gally that the play on words with ‘no-one’ is not as subtle as she might think it is.
Gally tells him that it is too late to change the name from Noone, not least because she and Susanna are planning to rename their act ‘Midnight & Noone’.
The two discuss Gally’s new stage name of Midnight, agreeing that it is better suited than Nightingale given Gally’s low voice. This gives Newt an idea for a song in which Gally would play the part of a man who impersonates birds.
