Plot summary
Researching the journal for any clues about Lori's weapon, Abbie and Ichabod discover a hidden message that connects to Hebrew lore; it tells of the "Sword of Methuselah ", which they believe to be the weapon. Realizing the connection between Franklin's Join, or Die cartoon and Sleepy Hollow's rivers, they attempt to track down the sword. Henry dispatches the Horseman to stop them, but he is forced to retreat at sunrise. Ichabod and Abbie discover a hidden underground lair, which is filled with statues, one of whom Abbie recognizes; Ichabod realizes that a gorgon guards the sword.
They manage to trick the Horseman into slaying the gorgon (since he is immune to its curse), but he is soon recalled by Henry, signaling the beginning of the Apocalypse. Ichabod and Abbie find the sword hidden by oil, and are able to obtain it by starting a fire. Elsewhere, Henry and the Horseman prepare to welcome Moloch's arrival.
