It's possible the sum of all the backward events, signs and other strange things will make sense only at the end, the very last show.  Or not.

Kim, you're absolutely right that it's good to look long and hard at the show, all the events and subtexts in there; that's what we're supposed to do, anyhow.  Frost and Lynch are pretty much daring us not to.

I may not agree with all of the ideas, think some of them are too way out, or people are seeing things that aren't there but... it's all good.  Discussion forums, for discussion.  Sometimes it's hard to get the emotional aspect or the finer nuances of speech and body language in an online format but I reckon everyone here has - for the most part - been friendly and open.

Me, I'm a contrary guy but for the most part I'm joking around.  Unless I'm not.  😉  If in doubt, read my signature. ? 

It IS very obvious. People are just not very good at catching this stuff and they get a little frustrated when somebody else does. There's a lot of other people talking about all this reverse scenes, specially the one with Hawk.   https://www.reddit.com/r/twinpeaks/comments/6mhuxb/s3e9_chief_hawk_was_in_reverse_when_talking_to/
No one knows what it means yet, but it's definitely very obvious and feels intentional. I think that maybe people who work with video in some way can tell instantly when the shot is reversed . It's not a feeling or a guess, it's just a clear reverse shot.

Thanks for sharing those reverse blink observations.

I saw what looks like backward blinking with Sonny Jim in the car and with Hawk right after when Mrs. Briggs says "they would ask me about Special Agent Dale Cooper".

Lynn, Interesting observation.  What I saw in the "Make sense of it" scene was two times when Dougie appears to smoothly, slowly, and deliberately blink, but didn't look like backwards blinking to me.  That feels to me more like he has spent so much time in the lodge that he seems to move at a slower vibration than the world outside.

For the reverse plane number, I notice that it appears to be on the side that only Diane was sitting on in the plane (excluding maybe copilot in the front?).

It does seem that people could be kinder in these forums when people are posting opinions, observations, and speculations.  Kim, I appreciate your post and observation, it made me pay more attention to those scenes.

I tend to be a big picture guy who doesn't spot details like that so the two Hawk gifs are really helpful to me. When I watched the first one I thought to myself, "I don't see it. He looks at the sheriff and then back at Mrs. Briggs. Normal." Then I saw it reversed and in reverse it looked MORE normal. Going back to the first gif it was clearly "off," or reversed. So thanks for the gifs, Rodrigo.
