As soon as the Governess is left alone with Miles, she misses her friend, Mrs. Grose. However, left in charge, she does her best to make everything run smoothly.
The Governess doesn't see Miles until dinner; after the departure of his sister and Mrs. Grose, he spent the day on his own.
The Governess struggles to act natural even in these odd circumstances. She and Miles discuss Flora's health; they eat a polite meal together while the maid is around, but, as soon as she leaves, he states, rather menacingly, that they're alone.
