What the F**k Happened This Season On 'American Horror Story'?

Keeping up with the various shenanigans happening in any given episode of American Horror Story can be a doozy, and this season especially has been a roller coaster. We've traveled back in time, been graced by the witches of Coven, gone to hell and back at least three times, visited Murder House, seen our favorite characters brought back from the dead and been treated to another legendary performance by Stevie Nicks. If you need a refresher on Apocalypse ahead of tonight's finale, we've got the crash course for you.
