Hi ! 

First of all sorry if my english is not 100% accurate, it's not my natural language so there will probably be some faults.

So, after viewing the last two episodes of Twin Peaks I've spent lot of hours on the topics of the Part 17 & Part 18 to see the differents theories about the ending.

Some of them are really interesting and founded by the way. This finale is really open for a lot of interpretation.

I was frustrated after the end of the Part 18 but I did not hate this last episode, so much questions and things that remains without answers.

But after looking into different theories and interpretations on this forum and other site what if everything is more simple than that ? Yeah, "simple" is maybe not in Lynch vocabulary  I know. 

But I was thinking a lot and then I just got a strange sensation that it's more simple than that and I maybe wrong but this sensation make the last two episodes less frustrating than it seems to be.

I think that those two last episodes are together for a reason, they could have release the last episode one week later but they didn't. 

What I think is that Lynch/Frost gave us two endings ?

The Good (Episode 17) and the Bad (Episode 18) and yeah I know that "good" and "bad" are really simple words to describe it.

At the end of Episode 17 Twin Peaks is sort of saved, Laura is not murdered (she dissapeard of this reality, so maybe she doesn't even exist here now). Everyone will enjoy their lives (expect Bobby cause he killed a dealer, sorry Bobby you're going to jail) without the oppression and the impact of the lodge, Bob is dead and Laura has disappeard from this dimension. (So the rape of Audrey may never happened, so I think she's safe)

Now Episode 18 begin with the new Cooper doppelganger created by MIKE going home and being reunited by Jane-Eye and his son. Twin Peaks end here, even if it's not the real Cooper, in a certain way everyone finally happy in TP dimension. 

Now go back to the "Judy" dimension, a sort of bad nightmare were Cooper/Richard seems locked with a Laura who is private of his real identity. Cooper and her are still alive and it seems that the fight of good (Laura) versus evil (Judy) is still on but will continue without us maybe for eternity and between them, Cooper (is it really the same Cooper that we know ? Look's like him without being him) a sort of neutral force who always got a connexion between the black and the white lodge. Cooper may play a part to a bigger purpose and he's condemned to always be the transmitter between good and evil in the infinite fight between them.

By the way the arm look (a tree) seems like a story with differents branches, like he know this one and know what's going to happen in this dimension.

This is my feeling about those two last episodes, love the entire serie, it was a spectacular experience, something that we may never gonna see somewhere else in TV. 

Thanks a lot if you read me ! Tell me what you think about it !
