What could be more Lynch-ian that doubling down on frustrating your audience?
Kyle McLachlan's acting talents are still being spent on the nearly-a-zombie "Dougie" character. The needle has moved just so slightly in that we learn he's an Idiot Savant at accounting fraud. Though a series of lines, doodles and drawings of ladders, he was able to show his boss something actionable in some case files.
I suspect that Lynch is going to finesse this all in the end, and here is my theory: Agent Cooper is actually sentient inside Dougie. He's stuck inside there just like he was stuck in the red room, the intermediary limbo dimension, and the glass cube. Like prisoners of war who find ways to communicate through taps and scratches, Coop has found a way to manifest crude actions through Dougie. When Coop finally comes out we'll learn he's been solving crimes and tying together the loose pieces of this season's numerous plots.
And Lynch is still introducing them. We have a semi-midget hit man who kills with an ice-pick, a psycho organized crime boss, and a disgruntled underling of same who runs over a child in his truck, and the return of the trailer park manager from "Twin Peaks: Fire Walk With Me."
And so I'll solider on, hoping for better in episode 7.
