She is shooed off at the end of the MOPS, and leaves the next day, to Skye's despair.
Rosalind makes frequent phone calls throughout the book, though she is kept in the dark about the severity of Aunt Claire's injury and Jane's nose injury.
She often skips out on engaging in childlike play with her sisters, and instead helps out with the adults.
Though she's clearly the one in charge of her "troops," she never comes off as bossy.
Rosalind comes home early with a junior named Oliver, who the rest of the family and Nick don't care for.
Rosalind is largely absent from while she vacations with Anna in New Jersey.
