Cady understood in that moment exactly why her and Jason had ended up together. They were both experts at sticking their heads in the sand. Their entire lives they had ignored all of the strangeness around them in order to protect themselves. Cady had built a wall around herself to protect herself from her strange family and Jason had done the same thing. Even now, Jason didn't want to be confronted with the ugly truth that Satan had cured him of his alcoholism.
Cady didn't blame him. She didn't want to acknowledge that either. Some part of her wanted to know so badly. She had a bottle of whiskey hidden in the house, hidden very well. She wanted to grab it now and pour Jason a shot and see what happened but what if he didn't cure him? What if it was all a trick? Cady wasn't sure that she wanted to know one way or another.
She smiled at him when he took her hand and said he had a lot of good things in his life and she was one of them. Would he feel that way about her when he realized what she had done? Would he feel that way about her when he realized that he was a pawn in her family's game? Because Jason had already spent so long being a pawn in his own family's game.
"I wouldn't leave you, Jason," Cady said honestly. "You would be the last person I would ever leave."
And she meant that so literally that when her father destroyed this city, she was only permitted to take Jason with her. Everyone else, including his sister and possibly her own brother, was going to die. She and Jason were meant to be the sole survivors.
It was a terrible burden to bear and to make Jason bear it now was unfair and Cady knew it. So she left it at that and let go of his hand so she could continue to eat. For now, it would be her and Damien's problem. There was no reason to drag Jason into it.
