He'd been working very hard to take care of his wife, which led to his son, Kyle, having a bump on his neck that hadn't been checked out. The bump was found to be a cystic hygroma that was cutting off his airway, which he needed surgery to remove. Allison also had her surgery, in which she was selected to receive the active agent.

Familial
