"If you would have..." She couldn't even finish the sentence before she was sobbing again, her ability to speak now totally and absolutely gone. She didn't want to think about that, think that if Sam hadn't been there when he had been that Jack wouldn't be alive. There's no way she could have handled his death with any kind of sanity, even with so many friends and family around. That would have been her breaking point, after which she wouldn't be sober for years into the future. She needed him here.
