Episode 18 - Dispute Between Brothers

In which we take a jump—"Three Days Later", the first and only time such a jump between episodes occurs—and check in with the other residents of Twin Peaks at the wake for Leland Palmer. It's Cooper's last day in Twin Peaks; with the wrap up of the investigation, he's headed back to Philadelphia, which leads to heartfelt goodbyes...until the fare-thee-wells are interrupted by FBI Internal Affairs and the Royal Canadian Mounted Police. Even though he's in trouble, Cooper takes it easy though, unable to affect the outcome of things out of his control, and enjoys a night of fishing with Major Briggs that also goes south when the Major disappears. What fresh hell has Twin Peaks unearthed for Cooper this time?
Also: Nadine enrolls in high school! Bobby gets thrown out! Audrey wears a suit! Norma meets MT Wentz! Josie returns!

Special Episode - Who Really Killed Laura Palmer?

**Deals with sensitive subject matter. Listener discretion advised**
In this special episode, we delve a bit deeper into the confusing questions that arose at the end of the last: namely, who is the true killer of Laura Palmer? Was this really a case of demonic possession? How culpable is Leland Palmer in the abuse and murder of his daughter? And who really is BOB?
Notes:
For more information, we cannot recommend Joel Bocko's incredible video essay "Journey Through Twin Peaks" enough! Here is his entry on the killer's reveal
While we're hesitant about any strict, dogmatic interpretations of Twin Peaks, the charges of misogyny leveled at both it and David Lynch in general have stuck around long enough to warrant mention here. Here is an essay that discusses it in relation to Laura's death and the reveal of Leland as her killer: 

Episode 17 - Arbitrary Law

Where we are joined by special guest Nathan from Edmonton for a look at Leland's trouble soul. With the blessing of the Sheriff and encouragement from the FBI, and using all the tools available in his Intuitive Detection Kit, Cooper sets off down the final stretch of his path as he gives himself 24 hours to solve the murders of Laura Palmer and, now, Maddy Ferguson. Meanwhile, Donna has a brief encounter of the inhabiting spirit kind when she visits the Palmer house and learns of Maddy's fate. Will Cooper figure it out in time to save her from the same terrible fate?
Also: Andy learns French! Lucy talks paternity! Ben finds his alibi! James gets on his bike and goes!
Notes
The Tremond grandson's name is Pierre.
Now that the horror of Leland's death has come and gone, why not watch him on the ridiculous "Tim & Eric's Awesome Show Great Job!" delivering advice on how to give proper business hugs!
Could the fire sprinklers be putting out the fire in Leland's soul? Sound off in the comments!

Episode 16 - Drive With a Dead Girl

The aftermath of Maddy's murder and the reveal of Laura's killer leads us into the realm of dramatic irony for the first time in Twin Peaks! Agent Cooper and Sheriff Truman get closer to figuring out the truth the audience already knows—that Ben Horne did not kill Laura—and Cooper gets reacquainted with his intuition, much to the Sheriff's consternation; meanwhile, Bobby dabbles in blackmail, and Norma gets a surprise visitor at the Double R.
Also! Does Ben need a new lawyer? How hard is it to keep the One Armed Man from escaping? And where does one go in a town like Twin Peaks for good, quality showtunes? (Apparently, all you need is a car and a set of golf clubs...) We may as well call this The Jerry Show since so many of our clips selected for this week's episode feature his classic deadpan humour, but after the darkness of last week's episodes, we were just so glad for Jerry Horne we couldn't resist!
Notes:
'Fahrt' translates to 'Journey', according to good ol' Google Translate. And now that we think about it, maybe farting (in English) is kind of like a journey... XD

For those interested in Canadiana: Hinterland Who's Who was a co-venture between the Environment Canada and the National Film Board of Canada started in the 1960s. They produced 60-second PSAs profiling various Canadian wildlife. Ask any Canadian who grew up into the early 1990s and they'll remember HWW. Here's the entry on the loon
The meaning of Hank's domino has never "officially" been stated as far as I can tell...but Chris Mulkey claims it was meant to be another instance of doubles (the two 3's equaling 6 total on the domino) while others claim it may be linked to the number of people he's killed. The blog Twin Peaks Explained states that the change in the numbers on his domino wasn't on purpose but was simply an error, owing to the fact that the original domino was lost during production and another was substituted.

Special Episode - Secret Diary of Laura Palmer

Wherein we discuss the 1990 tie-in novelization of Laura's secret diary. **Deals with sensitive subject matter. Listener discretion advised**
The Secret Diary of Laura Palmer lends itself well to critical, feminist, and psychological interpretations, and we touch on all three areas as we delve into the plot points, similarities and differences between the book and what we see onscreen, and the larger implications to TV audiences and pop culture consumers (especially considering the recent announcement about the Twin Peaks Funko Pop! dolls and action figures.)
*Apologies for ~20:30 when Lindsay whacked the microphone...she's a hand talker...*

Episode 15 - Lonely Souls

**Deals with sensitive subject matter. Listener discretion advised**
A killer is unmasked... In this week's episode, we are joined by our friend Jen, who watched Season 2 Episode 7 for the first time with us before joining us for a discussion. Who does MIKE "point" to at the Great Northern? What does Agent Cooper find in Laura's Secret Diary? How does Ben Horne fit into all of this? And who's that in the mirror there...?
Also: Pete gets a kiss! Bobby fixes Leo's new shoes! Nadine has a milkshake!

Episode 14 - Demons

In which we go over the aftermath of the raid on One Eyed Jack's—how much does Audrey remember? And how much will she tell Agent Cooper?—and Donna and Maddy's attempt at stealing Laura's diary from Harold. Elsewhere, Josie finds herself in hot water with Jonathan and Gordon Cole arrives for the first time to deliver some interesting news about a chess game...
Also: Leo has a party! Nadine buys a dress! Leland sings showtunes! Philip Gerard/MIKE takes up poetry! And what's this about a chihuahua?
Notes:
IT'S CALLED A CULTIVATOR!!!
Vicuna: I guess these are kind of like llamas or an alpaca...interesting choice for a coat!

Special Episode - On The Air

A special episode all about that OTHER Lynch/Frost production that ran on ABC during the early 1990s...the weirdly wonderful sitcom On The Air, starring Ian Buchanan and Miguel Ferrer as players on the ground floor of a decidedly off-kilter 1950s TV variety show. The show ran for 3 weeks before being cancelled by ABC, and although all 7 episodes have been available (in semi-official and bootleg form) for some time, it has never enjoyed a wide home release, in spite of many fans' hopes. Our discussion of this short-lived series is short, it's sweet, it's to the point, and there's actual bickering in it! How can you go wrong?
(Dedicated to the memory of Miguel Ferrer -- February 7, 1955 - January 19, 2017)
