Compare Suzanne’s and her mother’s reaction to Marguerite.

The Comtesse wants nothing to do with Marguerite and refuses to see her. Sunzanne, however, wishes to stay and see her friend, as is made apparent in the following quote from the novel:

Everyone in the coffee-room heard it and paused instinctively, listening to it for a moment. Sally was holding the candles by the opposite door, which led to the bedrooms upstairs, and the Comtesse was in the act of beating a hasty retreat before that enemy who owned such a sweet musical voice; Suzanne reluctantly was preparing to follow her mother, while casting regretful glances towards the door, where she hoped still to see her dearly-beloved, erstwhile school-fellow.
