Complete story — includes the ending
Dreyfuss experiences a vision of a world in which he has conquered the United States, with an elderly Ichabod as his prisoner. At an event for popular Internet star Logan McDonald, the star collapses from an unknown ailment after borrowing Molly's phone. At the hospital, another victim of the illness suddenly bursts into flames, confirming it to be supernatural in origin. Ichabod links the outbreak to a curse used by the British to burn Washington during the War of 1812. Alex soon reveals to Jake that she is infected as well. Fearing for the safety of the others, she flees into the catacombs. Jake and Ichabod are able to identify the distinctive symbol of the curse as belonging to a djinn, who uses it to lure victims to its lair and consume their souls. A team of agents led by Samuel Wilson managed to defeat the djinn with a powerful tempest, but only at the cost of Wilson's life. While conducting a ritual with Jenny, Molly has a prophecy of Crane being imprisoned. Jake takes the curse into himself, allowing him to find the djinn's lair. Diana injects Alex with a serum to cure her, and she and Ichabod kill the djinn by electrocuting it, breaking the curse. Dreyfuss informs Jobe that he is forming a "team" of his own, starting with McDonald.
