Okay, I think I understand now. They're splitting the finale into two episodes; Part 3: Take Back the Falls, and Part 4: Somewhere in the Woods. So that means the first half will have its own credits, and, presumably, its own cipher at the end of said credits. Just need to wait till the end of the month to see what it is.
