Félix J. Palma said this quote

Yes, he would look for her, whether to delight in the joys of spring together or to plunge into the abyss. He would look for her because he loved her. And somehow this would lessen the lie Claire was living. For, in the end, the girl's love was reciprocated, and Tom's love, like Shackleton's, was also unattainable, lost in the ether, unable to its way to her.
