"No, don't," Sam says immediately, "you're not. I just didn't expect this. You. But it's not your fault." It's hard to look at him, so she takes the excuse of picking up some of the kids' things and general straightening to keep her eyes and hands busy. "None of this is your fault."

In the movies, when someone gets back someone they thought they'd lost, it's a happy reunion and it's all fireworks and swelling music, but Sam doesn't feel any of that. She just feels numb.
