Thinking about the distant future hadn't been something that had been suited to this place, in Sarah's opinion, as there was always the risk someone would be sent back. She didn't think about that because, even though she knew he'd vowed early on he'd make certain anyone who wanted to stay would, thinking about that separation as even a slight possibility hurt too much. But that didn't change she had thought ahead, that for as much as she lived each day as it came, she still sometimes daydreamed. Even Heidi talking about home mortgages had pleased Sarah because of the normalcy as well as the future-mindedness of it.
But this wasn't a happy daydream, the idea of the 'future' for a man who could not die. For as much as knowing Peter would not be lost would be a comfort to those who loved him – not just her, but Nathan and Heidi and so many more (as she assumed others did know, even if she hadn't) – for Peter, it would be a curse in the end. She couldn't imagine it as anything but that for him, knowing how deeply he cared, how greatly he loved. He would watch everyone he loved grow old and die, not just his family and friends and her, but those he would love in the future. He would watch them all grow old and die. Over and over again.
It broke her heart.
Though his embrace was gentle, hers was fierce in return as she wrapped her arms around him again, not for herself so much as for him. For now, she just held him, keeping back fiercely whispered vows to barter for ambrosia or something equally definite and effective so as to be with him and not leave him surrounded by people but alone in the world, set apart because of this gift-curse. They were there in her head, but her focus was on him, reassuring him with her touch and the strength of it that she wasn't going anywhere.
