The reason I ask is because his truck was "stolen" by Richard Horne and then after he doesn't meet Andy and we never see him again. we just see some creepy shot of his house with the door open. This would makes sense that people would be looking for him. He doesn't seem like someone Audrey would be in love with but who knows?!? 

That being said, I believe Audrey is not in Twin Peaks. If she was, Sheriff Truman would have gone to see her in regards to Richard killing the kid, no? Why does he go to Ben? I believe Audrey is not herself, and Charlie is her doctor. That is why he doesn't want to tell her "what Tina said". He can't tell Audrey that Richard killed a child and is on the lam.

She's in some kind of fantasy world in her head. It's like she has vague access to news in the town and is getting it confused with this alternate reality she has created for herself in her mind. Maybe in her mind Billy is what she is calling someone else cause she can't fully remember his name (ahem, JJ wheeler). That could explain why when she is at the roadhouse dancing, and the fight breaks out, she snaps out of it and is in a white room. 

Just thinking out loud...

He then starts the 8th time with "Drink Full and Descend", therefore omitting the first lines "This is the water. And this is the well."

I suppose the number 8 marks a change.

(Forgive me if that's been mentioned before)

I agree that the red room is just a waiting room that is part of both lodges so that is why different spirits interact with Cooper there, both good and bad. 

First off, in the season 2 finale, the giant and "senor droolcup" both appear to him in the waiting room and in the return, it is where we always see mike, who is clearly helping the real cooper. It think the beings that live in the black and white lodges have access to the waiting room and it's a neutral zone (between them). That is why doppelgangers are just hanging out there too. It's an entrance/exit point

Secondly, in FWWM, Annie says "Cooper is in the lodge"- not black or white, which to me, means he's technically in the lodge but prob still just in the waiting room. Waiting for DoucheCoop who took his pot in reality, to return.

The convenience store is not the black lodge because Evil Coop just goes there no prob. He did not want to reenter the black lodge so he wouldn't go there is that's what it was. 

I'm not sure Cooper has even been to it. When Mrs. Palmer delivers the message to Briggs in season 2, it's supposedly from windom earle, who obviously didn't know everything he thought he knew (hence BOB taking his soul) so it could have just been his assumption that he had made it to the black lodge. Or maybe the other rooms were the black lodge? who knows? I just like reading the theories :)
