Just caught up and finished the ending. God that was haunting. Perhaps more than any scene or moment in the show, it captures the nightmare of Laura's life which can never be erased. Only manifest in different ways. Kinda puts a damper on FWWM's angel ending though.
I definitely agree with you about what the final scene communicates, but I don't think this contradicts Fire Walk With Me. I feel like they are both 'true'. This is another way at expressing the profound horror of Laura's existence, and by introducing Cooper into the mix, the confusion we feel when our lives become entangled with somebody experiencing such undeserved pain, and we realise how powerless we are to relieve them of it.
Fire Walk With Me still happened though. It's the other side of it - the relief of her soul in being freed from its suffering and the knowledge that she did the best she could. And, that Dale Cooper cared for her, enough to try to help.
All that said, I think Lynch probably felt it was too pat and easy as the final word of Laura Palmer. Even if relief comes, a horror that huge can never be fully escaped from. Her life has been touched forever. Trauma victims tend to be retraumatised again and again throughout their life. The echo of the pain calls out to her through her mind. It was the only right way to address the situation 25 years later.
I'm struck by how incredibly well thought through the message of this show is. The message of enjoying the small things, picking the right battles and accepting the mystery of life being the route to happiness is a great one for most people, but it would be downright insulting to a person who had experienced a trauma on the level of Laura's. Lynch is wise enough to acknowledge that there are some people for whom the possibility of happiness is outside of their control. We can try to help them like Carl with the grieving mother, but we can't pin our happiness on the hope of saving them like Dale Cooper.
I think people may be looking at episode 18 too literally if they consider it to be an alternate timeline or dream scenario. This was more Lost Highway than Mulholland Dr.
It's not quite a literal alternate timeline like Back to the Future, but I look at all of the dreams/timelines/possibilities as being equally true. Dougie seeing his family is the end to Cooper's tale just as much as his witnessing Laura's eternal scream, just different pathways possible through choosing to view the world in different ways.
The sync theory makes a ton of sense to me, especially with how both 17 and 18 were released at the same time. We always say that Lynch is intentional in everything he does, and I think releasing the eps concurrently goes along with that. Mrs. Tremond being played by a non-actor makes it even more compelling too
They were definitely released at the same time for a reason, which is that their final scenes echo each other. They're meant to be considered in relation to each other. Cooper trying to save Laura and failing at the end both times shows us that he has doomed to keep trying to do something that is impossible.
They were not released at the same time because Lynch wanted us to watch them simultaneously. Do people not see the irony of taking a conclusion with the message that some mysteries can't ever be solved and then going to elaborate lengths to 'solve the mystery'? This show tells us that we have to accept a lot of things as they are. Some people aren't listening.
