Philip and Louise’s interaction provides a moment of dramatic irony, when the reader knows something that the character does not. It is clear that Louise is in love with Philip, but Philip remains oblivious to this throughout the novel and often treats Louise poorly, despite the constant friendship she shows him. It is also interesting to consider Philip’s comment that Louise would have learned more than he did in Florence, because Louise will prove herself a perceptive character later in the novel, while Philip will constantly be making blunders and misreading other characters’ actions.
