I watched TWIN PEAKS back to back the weekend before last and it suddenly hit me for the first time that Josie is probably the clearest character depicting the Lodge Doppelgangers.  The Josie that we know from the start of the series is good, she closes the mill in Laura's memory and we soon discover that one the heroes of the show, Sheriff Truman, is very much in love with her. 

As the show continues in the second series we start to discover that Josie has a secret, dark past and that she is mixed up in a series of crimes, my feeling now is that it is Josie's Black Loge Doppelganger that is responsible for these actions and that somehow the good Josie is trapped elsewhere. 

Before, when Josie is seen trapped in the door knob after her death I took this to be a state of eternal punishment.  Now, however, I feel that it's Josie's Doppelganger that we see die on the bed, her body is significantly lighter because it is incomplete; it is lacking a soul and that it's the good Josie we see desperately trying to escape her drawer knob prison. 

Any thoughts?

I think it was all Josie. The Josie at the beginning of the show was all an act, IMO. Just like Laura was depicted as being the do-gooding all American homecoming queen, she had some mighty dark skeletons in her closet--as did most of the town of Twin Peaks *In a town like Twin Peaks, no one is innocent.". Same situation with Josie--she had some moments, like the ones with Pete, which I think were genuine, and a few with Harry, but if anyone got in her way, saiyanara. Like for instance once she had an idea that Coop was on to her, what did she do? Pumped him full of lead! Shot Jonathan, Eckhardt...that was all Josie. And I think she was trapped in the knob at the Great Northern because her soul got trapped---her love for Harry and her fear of being caught combined, the fear drawing Bob toward her, which I think is what ultimately killed her---her soul was caught in limbo so she became trapped in the wood. *I think that's what happened to Margaret's husband too--it's he who speaks to Margaret from the log*

The idea of Doppelgangers didn't surface until the last episode anyway.

The idea of Doppelgangers was intimated well before the last episode, Laura's Doppelganger appears in episode 2!

Yep! :)  And when Hawk talks about the Doppelgangers, or "shadow self" that every soul will meet as they pass through the lodge.

Yep...on the way to perfection---unless you enter with imperfect courage. Then some proverbial s*** will hit the fan! :O

This was not Laura's doppelganger in ep.2. This was Laura, in my opinion.

No, it's not Laura.  The LMFAP confirms this when he says, "She's my cousin... but doesn't she look almost exactly like Laura Palmer?".

Yes,LMFAP said this,but he was trying to confuse Cooper and in the same time to give him clues.We see later how Laura comes to Cooper and whispers her secret in his ear(My father killed me),and she didn't have white eyes,like that crazy Laura screaming at Cooper's face in ep.29

I think a lot is being made of the white eyes issue, my guess is that the decision to use white eyes in episode 29 was made in order for the audience to have a clear visual distinction between the actual person and their Doppelganger when seeing them within such close proximity in the Lodge sequence.

Yep!

Anyway,this was Laura's soul trapped in the lodge,Cooper and Laura had one and the same dream,which takes place 25 years later,but I don't think this was Laura's doppelganger?Then why to tell her secret to Coop?Doppelgangers are supposed to be the bad side of a person,so why to help Cooper,what for?

Why is she talking backwards?  I'm sorry but I don't see a connection between the backwards talking Doppelganger cousin of the LMFAP and the Laura we see in the Lodge with Cooper at the end of FWWM. 

This was a dream,this was a projection of the lodge,to give Cooper clues,to help him find out who is the killer.There everything is backwards,remember even Earle's speech.And about the end of FWWM,this is really the end-when Cooper and Laura are together,but actually this happened even before Cooper had gone to Twin Peaks to investigate.Future past,everything is mixed.Yeah..confusing,but,this all comes from the forces and physics of the lodge.There's no time.

This was not Laura's doppelganger in ep.2. This was Laura, in my opinion.

No, it's not Laura. The LMFAP confirms this when he says, "She's my cousin... but doesn't she look almost exactly like Laura Palmer?".

All this dream of Cooper is to help him "break the code and solve the crime" read the article about Cooper's dream on the section proj red room,here on the site,and you will see.

LMFAP 's "She's my cousin...but doesn't she look almost exactly like Laura Palmer?" is a clue for Cooper,to help him realise the next victim of BOB will be Maddy Ferguson(she is Laura's cousin and looks almost exactly like her)But the woman in the dream is Laura,not her doppelganger. 

I understand exactly what you're saying about the dream providing clues, but in the dream the woman doesn't claim to be Laura, the LMFAP says it's not her but his cousin and she says "I feel like I know her but sometimes my arms bend back".  So, this is not Laura, how can it "be" Laura this is just a dream, like you say.  It's a figurative representation of Laura, perhaps, but it's not "her", she's dead and this is a dream.

Later if we are to assume that Cooper physically enters the Lodge and that it isn't just taking place in his subconscious you see the same figurative representation of Laura (same costume / hair style) the only difference is the white eyes (which we agree were an after thought) so I take this image to be Laura's Doppelganger because the image of the actual Laura we finally see in FWWM is dressed and behaves very differently. 

Yeah...I think that "figurative representation of Laura" is the exact definition.It is not the real Laura.I agree it's just a dream!

Yeah...I think that "figurative representation of Laura" is the exact definition.It is not the real Laura.I agree it's just a dream!

Isn't a Doppelganger a "figurative representation" of someone?  I just think the visual similarities between what we agree is Laura's Doppelganger in the Lodge and the image in Cooper's dream point to them being one and the same, after all isn't backward talking another way to spot a Doppelganger aside from the white eye effect?
