In Animal Farm, Mollie's internal conflict is based on her vanity, laziness and materialism. These traits are clear from her first appearance to the reader in Chapter One when she arrives late to Old Major's meeting and spends the time "flirting her mane" and chewing on sugar. Even after the Rebellion, Mollie has little interest in making Animal Farm a success: she learns only the letters of her name, for instance, is always late for work and does not participate in the Battle of the Cowshed in Chapter Four when the animals drive humans from the farm. Mollie is, therefore, unable to put the needs of the farm above her own.
In Chapter Five, however, this internal conflict is resolved when Mollie suddenly disappears from the farm, never to be seen again. Her new life, however, affords her all of the comforts she desires the most: she eats sugar and wears a "scarlet ribbon" while a "fat, red-faced man" strokes her nose.
