Sarah held Peter, not needing words from him right now. She knew, she understood and the words would come later, in a hundred ways spoken and not spoken. Having him holding on to her as he was, having his mind touch hers as if often did, communicating things so intimately in a way nothing else could, was all the proof she needed of his feelings. She knew he could no doubt hear what she was thinking, but eventually her thoughts found voice just the same in a soft reassuring whisper, a promise that she wouldn't ever leave him and that someday she'd find a way to make that promise last longer than one human lifetime, but that they had time for her to figure it out, time to live and love both each other and those around them. For her, this was no lightly-made vow, nor would it be forgotten.
"I understand now why this didn't come up," she whispered, craning her neck slightly to kiss the side of his head, but otherwise having no need to move from this spot. "Thank you for explaining." She was happy to stay there as long as he wanted, his face tucked close and her cheek against his head as she stroked his hair. It was her reassurance to him that she was here, she was his and she wasn't going anywhere and from that same embrace was the reassurance of the counter, he was here and not dead, he was hers and he wasn't going anywhere.
"And I hope you'll stop waiting for the other shoe to drop." It wasn't mind reading by any means, as much as was just her own perceptiveness and understanding mixed with knowing Peter. A world of people had feared or rejected him for what he was, even if that world had thought it was another man connected with the explosion. It wasn't so hard to understand the small signs when a new ability was discovered or explained, revealing that part of him held slightly back each time, waiting. She hadn't known how to reassure him entirely, other than continue to love him as fully as she could, and she had been in no rush because she knew something like that needed to be seen and believed, not just said.
