Final answer:
The provided text doesn't mention Brian. Instead, it describes Warren's perspective as he observes dances at a club and contemplates his feelings towards Marjorie and her cousin Bernice.
Step-by-step explanation:
The student's question pertains to a scene where Brian was not explicitly mentioned waiting in any location, so the context seems to be mistaken or referencing another text. However, Warren is described waiting and observing the dances, and Marjorie, with her charm and popularity, is frequently in his thoughts. Clare, another character possibly confused with one mentioned in the question, is not referenced in the given passages. Warren is infatuated with Marjorie and finds Bernice lackluster by comparison.
Even in his begrudging obligation to dance with Bernice, it is Marjorie who captivates his attention. Bernice is frequently found dancing with the visiting boy, not Clare as implied in the question, and she simulates enjoyment in her social interactions, reflecting on how she was the architect of her own evening, despite Marjorie's influence.
