I think it's just showing us slices of life in Twin Peaks to underline how 'the light is fading' like Margaret said. My expectations for the ending, currently, is that the town is being poisoned both spiritually by what happened with Mr C and literally with the Chinese drugs Red is running through town. I think Coop being healed will restore things spiritually and I think Bobby is going to take care of Red and cut the head off of that snake too, removing the literal poison coming in via Canada. Espescually given that when we first catch up with Bobby he is clearly working to that end, even before being put at odds with Red with him and Shelly being a thing.
So those scenes serve to remind us that Twin Peaks is sick. That's my current thoughts anyway.
Yeah, I think there's a reason for those scenes and I think what you said is the reason.
But I just wish those scenes would've been written to better and more interesting.
There are countless of examples of single scenes with unknown people talking about unknown things that grab the interest of the viewer immediately and makes the viewer interested about the characters and makes the viewer want to listen really carefully what they say.
I wish the scene in last episode would've been like that. Instead, while I get the idea, it was very boring to listen to and left sour taste. A scene like that should not be the last scene of the episode. That's just a combo of bad writing and poor editing choices.
I mean, no.
Literally half of those can be answered with a single episode. It's obvious many plot lines are converging. And some stuff just shouldn't be answered directly ("what are the woodsmen" would be way too on the nose)
Now that Blue Rose has been explained I would not be surprised if some episode gave an explanation to the Woodsmen.
It could actually very well be that the "normal" stuff ends up being less explained than the lodge stuff.
