Jealousy between Richard and Annie reaches a new height when Richard wants to attend an operatic recital to which Caroline invited Annie months ago. The two squabble so childishly that an infuriated Caroline tells them off loudly - and the insulted diva walks off the stage and refuses to return. When Caroline sneaks into the star's dressing room to apologize and beg her to finish the recital, she winds up rubbing her feet and getting drunk with her on champagne, and returns home to find that Richard and Annie's mutual anxiety about her whereabouts has produced a sort of truce.
