Maybe it’s the return of the Huntsman- we know that’s going to happen in FTL.
It definitely has something to do with Katherine, though. Maybe Katherine and the Huntsman meet in FTL?
As for August, he could really either be Pinn or Bae. In this episode it very well could be about Bae. We know it will be about Bae in FTL, and we saw the preview for it in SB (August with the dagger). BUT I’ve heard the following episode, “the Stranger” is about Pinn. And we all know who the stranger is.
I know there’s a theory that August is both Bae AND Pinn. I don’t think this is possible, honestly…
But he COULD be both Pinn and the writer of the Storybook, OR Bae and the writer of the storybook.
The problem is, there’s a LOT of evidence for all three of these possibilities!
