Alan Griswold is the husband of Kimberly Griswold.
Alan's wife, Kimberly, had had several heart surgeries before, so when she had to have another one, they advised her that they couldn't stop her heart because it was too dangerous. Before her surgery, Alan, whom she treated poorly, snapped and yelled at her. She had a heart attack and had to be stabilized before her surgery. They took her into surgery and started operating. During her surgery, her chest cavity caught on fire. However, they were able to put out the fire quickly and finish the surgery successfully. Her husband was told she'd be okay, but he decided that he was leaving her.
