The film explores the circular nature of the characters' mistakes. Isaac leaves the devoted Tracy for Mary, believing Mary is his intellectual match. However, Mary is still in love with Yale. When Yale decides to leave his wife to be with Mary, Mary dumps Isaac to return to Yale. Isaac, devastated and realizing that his intellectual snobbery led him astray, rushes to Tracy's apartment to win her back.
The Ending: Isaac arrives just as Tracy is leaving for London to study acting. He begs her to stay, claiming he made a mistake and that their love is rare. Tracy, displaying maturity beyond her years, tells him she must go for her own growth but reassures him that 'six months isn't so long' and that he should 'have a little faith in people.' The film ends with a close-up of Isaac smiling wryly, realizing he has perhaps lost her, but also recognizing the truth in her words. The hidden meaning is that Tracy has outgrown Isaac; she is the one moving forward, while he remains stuck in Manhattan.
