Way, way back, it was always our intent to use the clock as a regular plot device. Increasingly more powerful demons would keep pouring out of it until, eventually, the wall between dimensions would come down entirely. Which, of course, sort of did still happen.
Anyway, I hope everyone’s enjoying this tale of Locke and Ence as would-be demon hunters as much as I am! I say that because there’s still at least two weeks of his arc left, so get comfy!
