Why It Shouldn't be Surprising that the new Chapter takes place Before the Huntress's.
If we are to take in the leaks regarding the Halloween Event, we know that our author isn't Benedict or at least a retconned version of Benedict. The last thing the author remembers was the sweet, milky smell of opium. Opium dens were very common in Europe and Asia during the 19th century and that's well before WWI. It's barely anything, I'm aware of that, but still, it's food for thought.
