Frank's daughter, Jordan, had had such an experience, when she'd contracted meningitis two years earlier in Seattle. But that was before the anthrax-like plague hit, and her mother let Jordan get the only antidote Frank had.
At one point, Frank confronts the angel, "Her mother died, so that she could live." "Did she?" counters the skeptical death angel.
"This isn't fair!" Frank argues with the angel. "She's the only good thing that ever happened to me! My wife died, so that she could live! She chose." "Did she?" responds the doubting angel.
Later, with Jordan in respiratory arrest, her lungs gushing with water, Frank, who never prays, shouts to the heavens, Job-like, "I tried, oh God, I tried! I did everything you asked of me. No expectations. I'm begging, don't take her away from me!"
Hearing Frank, the angel drowns in Jordan's stead.
Minutes later, Jordan tells Frank, "I saw Mommy.... Mommy said she's fine. And she said to tell you, she chose. She made the right choice. I don't know what that means."
"It means she loved you very, very much," Frank reassures her.
