When Sleepy Hollow first galloped (sorry) onto television screens two seasons ago, many viewers thought that it was unsustainable. After all, the tale of Ichabod Crane and the headless horseman is pretty straightforward, right? WRONG! The new Sleepy Hollow takes Crane (Tom Mison) out of the past and into modern New England to take on demons, culture shock, ancient prophecies, and of course, that pesky horseman. Along with Abbie Mills (Nicole Beharie), his talented, tough as nails partner in crime and the apocalypse, Ichabod has a whole host of challenges to take on.

And in honor of Sleepy Hollow: The Complete Second Season Blu-Ray release this week, we’ve got a supercut of 13 things you need to know about the show before the third season. There are some details you might know, like succubi are sultry demon temptresses or that the headless horseman is a man, not a horse-man… but if you want to learn more about a preserved Thomas Jefferson, demon babies, and how to bring — er, prevent — hell on earth, you might want to take notes.

Sleepy Hollow returns Thursday, October 1 at 9/8c on FOX. Don’t miss the SleepyCast, our podcast recapping seasons 1 and 2, right here on Nerdist.
