After Lincoln is shot dead by a member of the Magus, Jahel disobeys her father and Emmet by calling upon the river's spirit for help. With the help of Tess, Jahel performs a ritual which brings Lincoln back to life. Lincoln tells the crew that Kurt shot him, when later it is revealed to be Jonas. With an evil spirit inside him, Lincoln kills Jonas. Clark discovers Jonas' body and the crew realize the truth about what is happening—the Boiuna's spirit is living inside Lincoln. Emmet asks Lena to help force the evil spirit out of his son and they perform an exorcism. When it does not work, Emmet asks Kurt to help, who tells him that he needs to talk to his son, not the spirit. Emmet does so, which results in the spirit leaving. The crew then tries to follow the map out of the Boiuna to a fishing village for supplies, but find that it is not there when they arrive. Clark sends up the heli-cam to inspect the surroundings. On a monitor, the crew sees that the river and terrain are changing, to which Lincoln explains that the Boiuna will not let them leave.
