The single-mindedness and focused intent were characteristic of both father and son, and though the son had never turned up in the Halls of Mandos as he was supposed to, the time he had spent wandering as an unbodied spirit and then as a self-reembodied Elf had paid off as reflective, contemplative time. He had not the constraints that his father had had, but the results had been similar. He had had to consider the consequences of the decisions he had made in life, and he had come to the conclusion that he might have made better decisions.

And so, in the worlds he had lived in since his death, he had chosen to help others whenever he could.

And here, he was somewhat aware of his father's thought processes, not because he was trying to overhear but because they were so alike that they were attuned to one another in ways that were hard to describe.

He follows his father between the buildings and they locate as many people as they can. Some of those people help with the search.
