The strikers' valley represents rational selfishness, the belief that an individual should pursue the life-enhancing values that promote happiness. To marry Dagny would make Galt happy, but he loves Francisco as well and knows of Francisco's feelings for Dagny. Will Galt sacrifice his feelings for Dagny so Francisco can pursue the woman he loves? For Dagny, the question involves far more than a love relationship. The question involves everything for which Galt, his strike, and the valley stand. Galt's actions remain true to the values that give his life meaning; he refuses to relinquish one moment of his private time with Dagny, not granting to Francisco the chance that he himself desires. Galt's integrity is rock solid. He pursues the love on which his happiness depends, no matter what the circumstances.
Dagny thinks that she has a chance to defeat the looters because she still believes they're rational. Dagny believes that the looters want to live and that they're honestly mistaken in their principles and policies. She thinks that they only need to realize that their altruist ethics, dictatorial politics, and socialist economics are leading to collapse. When the looters see their errors, they'll step back and permit rational producers like Rearden and herself to rebuild the economy. For this reason, Dagny believes that she must return to her railroad.
Galt and the strikers, on the other hand, believe that the looters are irrational — that they're viciously driven by the urge to rule men. The strikers think that the looters see the destructive results of their policies but choose to deny the truth. When reality clashes with their desire to rule and prosper, they evade reality rather than question the desire. They want power regardless of the consequences. Therefore, no amount of evidence that proves the devastating results of their policies will motivate them to change. Galt feels certain that Dagny can't win her battle and wants to be near her when she realizes it too. At this point in the story, the reader is not certain whether Dagny and Rearden are right or whether Galt and the strikers know the truth.
