Complete story — includes the ending
In the antechamber of the temple, Ichabod restores the box, but soon realizes that the soul of a Witness is needed to use its power. Betsy is able to return to her own time while Abbie, who feels the effects of the box, joins Ichabod and Jenny in confronting the Hidden One. Ichabod returns the box to Pandora who uses it to absorb the Hidden One's power, but without a soul, the box is useless. Abbie sacrifices herself, while Ichabod and Jenny watch helplessly. As the Hidden One is now mortal, Jenny kills him. Ichabod revives the Horseman, and allows him to take his revenge on Pandora. A dying Pandora reveals that Abbie cannot be resurrected, and Ichabod has a heartfelt goodbye with her before she moves on to the afterlife. At Abbie's grave, Ichabod learns about a secret order founded by Washington from Jenny's father. Ichabod vows to find the next Witness after learning that Abbie's soul will soon be revived in another's body. He then leaves for Washington D.C., assisted by members of the order.
