1. Recall that the Headless Horseman is only one-fourth of the problem in this incarnation of the Sleepy Hollow legend.
2. Headless is also the reanimated body of Abraham, Ichabod's ex best friend and former suitor of Katrina, Ichabod's wife.
Yep, that's the same dude. Figures that Ichabod personally knows Headless. He apparently knows everybody from his time period.
3. Case and point: Ichabod offhandedly mentioned that he used to date Betsy Ross.
4. And Ichabod used his personal knowledge of George Washington's habits to help Abbie find a map to purgatory.
5. Katrina was finally rescued and brought into the present time period!
6. But Abbie had to stay behind in purgatory to take Katrina's place.
"Still not bothered" — the shippers
7. In a HUGE plot twist, Henry the sin eater turned out to be Jeremy, Ichabod and Katrina's long-lost son!
8. Henry/Jeremy was mad about being abandoned and half-killed by Katrina's coven.
9. Like, really mad.
10. Henry/Jeremy then traded his mother to the Headless Horseman (see how that love triangle came full circle?) in exchange for a seal of the apocalypse.
11. Because Henry/Jeremy also happens to be the Horseman of War.
12. In fact, it was Henry's rebirth as the War Horseman that Abbie and Jenny saw in the woods so many years ago.
13. Actually, Jenny discovered The Plot Twist before everyone else, and was (maybe) taken out by the Headless Horseman before she could tell anybody.
14. Shit, Captain Irving confessed to double homicide and is in custody.
15. Andy Brooks was transformed into an alien-eyed monster and buried alive in George Washington's Masonic tomb.
16. Now that Henry broke the second Seal of the Apocalypse, he has the power to call his Horseman bros together and bring about a demonic war that will end the world as we know it.
17. And all of our heroes are either incapacitated, incarcerated, or dead.
