haha oh man I wish I could begin to shed some light on it. The show is really deep. I suggest you start from episode 1 (its on Demand with Comcast).
Here is an article about the last episode. This is just about the last episode, so you can imagine the show is pretty intense:
"Inside the Episode
With Steve Hawk
Now that the defining transgression of Cissy's life has been revealed (decades ago, high on LSD, she gave her teenage son a hand job), it's worth going back to take a closer look at a couple of foreshadowing moments from the two preceding episodes.
Near the beginning of Episode 4, when Butchie wakes up at his parents' home and strolls into the kitchen in his underwear to find his mother sipping coffee, their discomfort is acute. Without knowing why, each feels compelled to flee. During rehearsal, David Milch (the show's co-creator, head writer and creative overseer) suggested that Brian Van Holt (Butchie) and Rebecca De Mornay (Cissy) behave like a couple facing the embarrassing moment of goodbye after a drunken one-night stand. Here's how the narrative reads in the script: "In a strange semblance of a dance move they clear each other. An inexplicable awkwardness between them." Now you know why.
A more subtle presaging occurs in the middle of Episode 5, when Butchie asks Cissy to let Tina (his ex) visit Shaun (Tina and Butchie's son, over whom Cissy has custody). Watch Butchie's reaction as Cissy berates him: "I thought you were an idiot before you started shooting dope, but you were a 12-year-old genius compared to the stupid f**k you are now. As much acid as I took I was never as stupid as you."
At the words "12-year-old genius," Butchie starts to rub his neck, and the moment Cissy mentions her acid trips, he bolts. Cissy's compulsion to deliver those trigger words, and her son's reaction, fail to rise to the level of consciousness.
Get Out If You Can
A surf note: In the episode's second scene, Cissy phones Mitch, who's on his way to a spirit-cleansing surf trip to Mexico. "I hope it's pumping in Salsipuedes, Mitch," she says. "I hope you catch some real soul-searchers."
Salsipuedes is a rarely surfed pointbreak about an hour south of the U.S.-Mexico border, best on giant west swells but also sometimes enjoyable when the waves are small and out of the south. The dirt road that descends to the ocean there is steep and treacherous and impossible to navigate when muddy.
"Sal si puedes," translates to, "Exit if you can."
No Stunt Musicians Needed
Near the episode's end, when Freddy (Dayton Callie) plays sax and Bill (Ed O'Neill) plays harmonica, those are the actors performing on their own instruments. Dayton used to play sax professionally, and O'Neill blows a mean harp.
Johnny Monad's Big Speech
John's extraordinary speech at the end of the episode is bound to trigger much discussion. I'm not in a position to enter that fray, but I can say this: all but a couple of John's statements will make sense to anyone who follows the show, listens closely and think it through. In the interest of abetting that process, here's a transcript:
"If my words are yours, can you hear my Father? Can Bill know my Father, keeping his eye on me? Can I bone Kai and Butchie know my Father instead?
"My Father's shy doing his business. Kai helps my Father dump out. Bill takes a shot. Shaunie is much improved.
"Joe is a Doubting Thomas. Joe will save Not-Aleman. Joe will bring his buddies home. This is how Freddy relaxes. Cup-o'joe, and Winchell's variety dozen.
"Mitch catches a good wave. Mitch wipes out. Mitch wipes out Cissy. Cissy shows Butchie how to do that. Cissy wipes Butchie out. Butchie hurts Barry's head. Mister Rollins comes in Barry's face. My Father runs the Mega-Millions.
"Fur is big. Mud is big. The stick is big. The word is big. Fire is huge. The wheel is huge. The line and circle are big. On the wall, the line and circle are huge. On the wall, the man at the wall makes a man from the circle and line. The man at the wall makes a Word on the wall from the circle and line. The Word on the wall hears my Father.
"The zeroes and ones make the Word in Cass's camera. In the Word on the wall that hears my-Father-in-Cass's-camera, the good one Mitch catches doesn't wipe Cissy out. In the-Word-that-hears-my-Father, Cissy shows Butchie something else. In-my-Father's-Word, Cissy shows Butchie in Shaun. In-my-Father's-Word, Tina raises Shaun at lunch. In Cass's-camera, Butchie lays the court out for Barry, and Mister Rollins watches, and he doesn't come on Barry's face. In Cass's-camera, Butchie knows Kai kept the faith. In-my-Father's-Word, the Wave lifts them up.
"In Cass's camera, Bill doesn't bump his head on the stairs. In Cass's-camera, as long as he's being stupid, Bill gives Lois a kiss.
"In His-Word-in-Cass's-camera, the Internet is big. Nine-Eleven is big, but not every towel-head is eradicated. In His-Word, We are coming Nine-Eleven-Fourteen.
"In my-Father's-Word, Bill sees how Freddy relaxes. In Cass's-camera, Ramon wants to know who's hungry, in the courtyard and Room Forty-Five.
"In my-Father's-Word-to-come-in-Cass's-camera, Doctor Smith calls Ocean Properties. In Cass's-camera-to-come, my Father stares Not Aleman down, and Freddy sees Bill much-improved.
"You will not note my-Father's-Word, nor remember Cass's-camera, but you will not forget what we did here."
And with that, John's spell is broken.
