When the first teaser for season eight dropped in early August, one scene in particular struck me. In the vignette, a demon hand slices open a fig with a single nail and two scorpions spill out, like guts, onto the ground. One is black and one is white, and they proceed to mercilessly attack each other.
Here's why I'm getting crazy Bible vibes from this part: both the fig and the scorpion are specifically mentioned in the Bible. Even more interestingly, the fig appears in Genesis — Adam and Eve make clothing out of fig leaves after they've committed Original Sin — and the scorpion is mentioned in the Book of Revelations: "And their torment was as the torment of a scorpion when he striketh a man; and in those days shall men seek death and shall not find it: and shall desire to die, and death shall flee from them."
If you take the symbols and run with it, we're seeing the beginning and the end. It's a pretty solid hint that the Book of Revelation aka the Bible's version of the apocalypse may come into play as the eighth season of AHS unfolds.
