What Mr. C wants
If this is what Mr. C wants (thank you Nikolaj Nielsen, for posting this in Episode 8) ....
....could he be hinting at a situation where the Lodge opening inbetween the two peaks turns to a Big Dark Black Lake, so when the portal opens the whole of Twin Peaks turns into a One Giant Black Lodge? On Major Brigss's note we see a similar situation coming up for 10/2
Could this what we are IN for in the final episode 17/18?
