Being present for Ingrid’s suicide seems to have made Henry recognize the inevitability of his impending death more clearly than he has ever before. Though he’s admitted to Clare that he knows he will die, he has been scant with the details. Now, in addressing logistical matters of his will, letters to give to loved ones, and other official or important documents, he shows that he is done ignoring the inevitability of his death and is choosing to be practical about things instead. Whereas before he seemed to think it best to spare Clare the pain of thinking about his impending death, now he seems to acknowledge that it’s best for them both to accept his death while they are both around in the here and now to process the impending tragedy together.
