A lot of stuff in this episode, including a couple of cool details related to the awesome ep.27...

-The Meals on Wheels plate next to Harold’s door when he opens it.
-Coop says Maddy saw BOB twice, both times in visions, one was in Donna’s house after “Just You and I” and the other one refers to BOB’s vision in the carpet, only seen outside the US.
-In the scene with James and Hawk we can see Albert leaving. Easy to miss.
-In the scrabble Lucy uses to form words with R, B and T we can see that she already had some as she mentions later. Ex: Rabbit.
-Did I say that she uses a scrabble? That’s hard to spot too…
-Coop asks Hawk to leave because he wants to talk to James but later we see him right behind them.
-A service bell (like one from a hotel) in Lucy’s desk.
-Obvious but must be mentioned: there’s a “No smoking” sign at the Sheriff’s station yet Dick lights a cigarette. That’s why Hawk says “prohibited” later and breaks the cigarette.
-A sign behind Leland reads “Is your job a bore? Not anymore. Be an E.A. deputy sheriff."
-Leland throws a match to an ashtray. What’s it doing there if smoking is not allowed?
-A Double R Diner cook talking on the phone behind Dick.
-James and Maddy are not in the booths behind Lucy and Dick though we inmediately see them there later. The people behind James and Maddy are the same though.
-After Donna enters we see sitting in a booth the same woman that in ep.27 is seen shaking her hand while eating pie. She wears the same hat too. We'll see that woman again before ep.27.                 
-Nice detail: BOB’s sketch still is at the Double R door.
-The OEJ girl who films Audrey while she’s being drugged is the new girl from ep.2.
-The broken toilet in the sheriff’s station restrooms. Indicating that it’s broken there’s not only a sign, but also a police tape!
-The school band members and cheerleaders leaving the elevator with Coop…and the way he looks at them.
-The cheerleaders reading magazines next to the hotel’s gift shop, in the Timber Room.
-A book about owls sitting in a table in the Timber Room (Hawk is seen reading this same book in ep.27).
-Barely seen, but Nadine’s name is written in her cuffs.
-A nurse holding a vase with huge flowers right before Coop and Harry enter Jacoby’s room.
-Jacoby mentions that his wife Eolani and him are trying a Kahuna healing method and that’s what the book he’s reading in that scene is about.
-A collection of rocks next to Jacoby’s bed very similar to the one he asks Harry to hold.                
-Laura’s tombstone indicates that she was born on July 22nd 1972, which matches the date given in the published secret diary. It's a wrong date, though, because it places the show in 1990 and makes Laura 16 at the time of her death...                                                                                                                                                               -The scene where Donna finds James and Maddy together and gets mad is filmed in a way that we notice that she’s there at the same time James and Maddy do. However we can see her reflection in a painting in a wall moving where she later stands.

Was Ronette physically trying to escape the hospital because BOB (Leland) came to kill her after the train car vision?

I like when Harold sees Donna crouching down looking at the page sticking out of the secret hiding place and he doesn't even flinch or acknowledge her actions

I never noticed Dick Tremayne has a theme song, when he first enters the sheriff's station (a sad reminder of dugpa's post that Lynch said there will be no more TP music soundtracks)

Am I hearing things - does Blackie drop the F bomb after shooting Audrey up with heroin?  (go back and listen)

Did the production crew add some sort of voice effect to the One Armed Man's voice when he is in the sheriff's bathroom screaming?  (sounds otherworldly)

James is very respectful of the Palmer household when he shoves a lamp onto the floor in frustration.  (I would have decked his teen angst face)

"If life could only be like those summers up at Pearl Lakes." When Leland is consoling Maddy right before Cooper and Truman come arrest him for Jacques murder - is this an ominous reference to BOB possession? 

"Harry, I'm going to let you in on a little secret. Every day, once a day, give yourself a present. Don't plan it, don't wait for it, just let it happen. Could be a new shirt at the men's store, a catnap in your office chair, or two cups of good, hot, black coffee. Like this."  -Dale Cooper

"What Ben Horne would do to get his FUNKED up daughter back, I'll buy the bastard out."

 It's FUNKED, but of course it's done in a way to get past the censors which is just brilliant on their part.

"Harry, I'm going to let you in on a little secret. Every day, once a day, give yourself a present. Don't plan it, don't wait for it, just let it happen. Could be a new shirt at the men's store, a catnap in your office chair, or two cups of good, hot, black coffee. Like this."  -Dale Cooper

D'oh! The scenes I mention that take place in the Timber Room...well, they don't! That's the lobby of course....
