While the sixth installment of Showtime's Twin Peaks: The Return didn't address the bombshell it dropped in the last episode — that the fingerprints of the long-deceased Major Garland Briggs (Don S. Davis) had resurfaced — it wasn't short on new developments for a variety of mysteries the revival is attempting to solve.
After a very scattered fifth episode, Part 6 focused mainly on only two locations, one of which is the titular Washington town itself. In the previous episodes, the fictional town played a small role as Deputy Hawk (Michael Horse) began investigating the disappearance of Agent Dale Cooper (Kyle MacLachlan) and viewers were introduced to Shelly Johnson's (Madchen Amick) daughter Becky (Amanda Seyfried). After the events of Part 6 though, it's going to be hard to stay away from the town again.
That said, the goings-on in Twin Peaks were definitely not the biggest events to take place in the episode. Instead, those honors go to the introduction of a character fans of the original Twin Peaks have been waiting more than 25 years to meet.
Diane Finally Appears
Albert Rosenfield (Miguel Ferrer) and Gordon Cole (David Lynch) said there was only one person who could help them to determine whether or not the evil Cooper doppelganger was the genuine article. And in Part 6, that person was revealed to be none other than Diane Evans, Cooper's longtime confidant who was never seen in the original series.
That role has now officially been filled by Laura Dern. Albert finds her sitting at a bar with a drink. Unfortunately, the episode doesn't dig into their conversation, just the greeting they share. Hopefully it's not something fans will have to wait long for.
Still, introducing Diane is a huge moment for Twin Peaks. Not only does it provide a likely bridge to get Cooper out of his Dougie Jones funk (more on that below) but if anyone's going to know the doppelganger is lying, it is bound the be the one Cooper was closest to.
The Life and Times of Dougie Jones
Much of the episode again followed a catatonic Cooper as he continued living Dougie's life. After being brought home from work by a security guard, the secrets Dougie was hiding started slipping out. It was revealed to his wife Janey-E (Naomi Watts) that not only was he cheating on her with Jade (Nafessa Williams) but that he owed a bunch of money to a loan shark after making a losing bet on a football game.
While Janey-E pays off the overdue loan to the thugs who want to beat Dougie up, he's not out of the woods just yet. Duncan Todd (Patrick Fischler) pulls a file from his safe that is then sent to assassin Ike "The Spike" Stadtler (Christophe Zajac-Denek). In the file are photos of Dougie and Lorraine (Tammie Bird), the woman who originally put out a hit on him.
From there, "The Spike" gets to work. He quickly tracks down Lorraine and butchers her and any witnesses with an ice pick. He's yet to find Ducky, but clearly Todd and his boss want him dead.
It's not all bad news for Cooper, though. This episode saw him finally get back into a black suit and begin speaking a little bit more. He also scribbled all over a bunch of files he took home from work, uncovering some dastardly dealings that his boss was pleased to find out. The show also reminded viewers about Cooper's connection to the Red Room, as he sees a vision of the One-Armed Man (Al Strobel) who tells him, "You have to wake up. Wake up. Don't die. Don't die. Don't die."
Little by little the old Cooper is starting to emerge, but it really is going at a snail's pace.
Meanwhile, in Twin Peaks
After viewers were briefly introduced to Richard Horne (Eamon Farren) in Part 5, Part 6 is where they learned how depraved he was. After meeting with drug supplier Red (Balthazar Getty) — the man Shelly saw in the bar — and sampling his product, Richard leaves in a rage when Red refuses to stop calling him kid. 
Red plans to use Richard to distribute his drugs over the border from Canada. That plan may be sidetracked though, as in his fury Richard runs a stop side, hitting and killing a small child. He does not stop as the child's mother runs to him sobbing. Instead, he quickly drives out of town before pulling over to wipe the child's blood off of the front of the truck.
It's a tragic moment in the series and one that, like much of what has been happening in the town throughout the revival, feels real and raw. While Cooper is locked in some sort of supernatural battle with his own double to figure out which one can stay in this dimension, the things happening in Twin Peaks carry a kind of emotional weight that hasn't been seen elsewhere thus far.
It all seems connected to something larger though, as Carl (Harry Dean Stanton) made his return and saw some sort of spirit or essence escape from the child and float to the sky. He mutters the word "God" before going to the grieving mother. The mist that arose from the child's dead body certainly speaks to something bigger and quite possibly related to the Black Lodge. At this point though, it's too early to guess what.
Finally, at the Twin Peaks Sheriff's Department, Hawk is seen cleaning up after using the restroom. When he drops a buffalo nickel and it rolls into a stall, he follows it before noticing something suspicious about the stall door. He then dismantles it, finding multiple hand-written pages inside. The show does not reveal what is contained in them but given that the Log Lady (Catherine Coulson) said that only he could figure out the mystery behind Cooper's disappearance, chances are there is something very important to be found in those pages. One very real possibility is that these are the missing pages from Laura Palmer's (Sheryl Lee) diary. Should that be the case, hopefully the show revisits this story thread quickly.
Twin Peaks: The Return airs Sundays at 9 p.m. on Showtime. Keep checking with THR.com/TwinPeaks for continuing coverage of the series.
