Hey everyone

 The reason for Doc Hayward's reaction was, for me at least, a clue as to what happened to Ben Horne. If he was dead, would the Doc be standing at Cooper's bedside? I find that doubtful. When Truman mentions Annie is in the hospital, the Doc's reaction suggests to me that Ben Horne is also there.

Thanks

That's what I've always thought of that moment - the Doc has a cloud over him, as Ben Horne is alive, most likely in a coma. If Ben were dead, wouldn't Sheriff Truman have him locked up?

Haven't posted here in a while, but here's my view:

I'm pretty sure Coop's stuck in the Black Lodge forever. I don't think there's any way to get back out when you don't have your soul...I think that for the entirety of Twin Peaks (except for a lot of irrelevant season 2 episodes) is a game between the spirits to decide the fate of Laura's soul. I'm not sure exactly who's on who's side, but I know that BOB is on the side that wants to keep Laura's soul in the Black Lodge. Because he didn't manage to possess her and overcome him, he doesn't have that right. But for some reason (maybe she isn't pure enough to go to the White Lodge) she is stuck in Limbo, or the Waiting Room, until her savior comes (Cooper of course). I think that Coop was predestined to save Laura...anyways BOB plays an elaborate trick (which runs throughout pretty much the entirety of the show... maybe even in events that take place before the start...) to trap Cooper in the Black Lodge, only for BOB to have the trick played on him since Coop saves Laura's soul. I'm not clear on a few things though (i.e. how Coop gets back in Limbo for FWWM). This is the ultimate end of Twin Peaks; it didn't go on because both the stories of Cooper and Laura are now wrapped up... without them, the show is nothing. I imagine Annie would inform Harry about Coop and he will die a death similar to Leland's.

Anyways, concerning Annie, Laura, Caroline, and Windham Earle:

 I have a theory that Laura does not have a doppelganger at this point because she's in limbo. There is no proof that we actually see Laura's doppelganger. When she screams at Coop we see Windham Earle's face, blurred, briefly (a much ignored moment). Windham is taking Laura's form. I think he was also Annie and Caroline when they're talking to Coop (the real Annie appears elsewhere briefly). Also think about the significance of these three... they are Cooper's past, present, and future loves, and we all know that Windham likes to meddle with Coop's love life... I think much of the Black Lodge finale is Windham tormenting Coop. BOB is allowing him to control the Black Lodge to make him think he's in a position of power. I also think that Maddy and Leland are merely cameo appearances that Lynch decided to throw in. I doubt they mean anything. They are doppelgangers because everyone that lives in the Black Lodge is a doppelganger. I also doubt that Annie would die, since she obviously knows that Coop is possessed.
