Why did Georges think that Helene redirected her affections towards Walter Rogers?

Context: Papa Chibou, the elderly caretaker of Musée Pratouchy, a Parisian wax museum, feels a strong kinship with the figures, particularly with that of Napoleon. He spots at the waxworks a romantic young couple, Georges, a lawyer, and Helene, the daughter of a stern judge who disapproves of his daughter's choice and forbids her to see Georges. Papa Chibou suggests to them that they can still stay in touch, without disobeying her father's directive not to speak with each other, by placing secret personal messages in the pockets of Napoleon's uniform. However, a missing letter and confusion in communication causes Georges to arrive at the mistaken conclusion that Helene has redirected her affections towards a foolish young man, who is unworthy of her and excessively preoccupied with his stylish personal appearance and elegant clothing.
