Plot summary
Ichabod and Abbie investigate a case involving two sisters; the younger had fallen into a mysterious coma, and the other tells them that she witnessed her sister being attacked by a monster. They learn that the creature responsible is called the Abyzou, which Ichabod likens to the Tooth Fairy once they discover that the demon targets children who are about to lose, or have lost, a tooth and feeds on their soul. Ichabod remembers that Betsy Ross was in a similar situation with her niece, and had enlisted the help of Paul Revere, who used silver to drive away the Abyzou. At the hospital, Pandora, posing as a nurse, persuades the older sister to offer herself to the demon in order to save her sibling.
