Before Will, Tom largely avoided thinking about Rachel and his dead infant son due to the emotional pain they caused him. By now, however, his father-son relationship with Will has healed Tom’s grief sufficiently that he asks his mental Rachel for advice—and she suggests that he “kidnap” Will, saving him from the orphanage. In a sense, Will saved Tom from his grief, which leads Tom to save Will in this moment. Alf’s approval of Tom and Will’s reunion suggests that Tom’s fatherly love of Will is clear even to outsiders—though Alf presumably does not know that Tom is taking Will away without any kind of official permission.
