Breaking Bad

Season 5

Live Free or Die

1. At the start of the episode, Walt breaks his bacon into pieces and makes it into 52, referring to his age. In the pilot episode, his wife Skyler made his veggie bacon into a 50, where he turned 50.
2. Old Joe compares the feasibility of Walt's mobile super-magnet to that of "string theories and God particles", in this episode first broadcast July 12, 2012. Just eight days prior, on July 4th, the actual long-sought "God particle" (the Higgs boson) was detected for the first time by the Large Hadron Collider on the Franco-Swiss border.
3. The Cadillac that Mike drives to meet Walter and Jesse (and abandons afterwards) is the same car Jesse took from the Cartel party in Salud (episode #4.10).
4. The episode's title, Live Free or Die, is the slogan seen on Walt's car's licence plate in the opening scene.
5. Throughout the entire series, Vince Gilligan uses symbolism with the characters color of clothing. In the beginning of the episode, Walt is wearing a green shirt when he kills Gus and when he gets home. The color green represents greed, jealousy, ambition and growth. After he cleans up everything he used to make the bomb, he changes into a blue shirt. Blue represents royalty. Symbolizing the crown has switched hands from Gus unto Walt.
6. The episode title "Live Free Or Die" has the same name as a sopranos episode which was an episode in the final season like Breaking Bad
7. Curiously both Mike Ehrmantraut and Tio Salamanca own the same humidifier.
8. In the Season 5 premiere's opening scene, Walter White is shown having a gloomy 52nd birthday breakfast at a Denny's in Albuquerque while showing a New Hampshire drivers' license with the last name Lambert, coughing and taking medicine, not wearing a wedding ring, and paying a gun dealer who was seen in Season 4's "Thirty Eight Snub" for an M60 machine gun. In an August 2012 Rolling Stone article about the 5th and last season of the show, Bryan Cranston revealed that Vince Gilligan told him a few key facts about this scene: Walt was returning to New Mexico from New Hampshire by himself, he had come back and gotten the machine gun to protect someone, and his cancer is "possibly" no longer in remission.
9. At the start of the show, they show a car Walt has been using whilst on the run. The registration is 3272153. This is the SID number for methamphetamine on PubChem, a database of chemical molecules maintained by the National Center for Biotechnology Information.

Madrigal

1. The Madrigal building was really a newly built high school that had not yet opened.
2. In the Madrigal building, the logo for Burger Matic is seen. This was the name of the restaurant in creator/writer Vince Gilligan's Home Fries (1998).
3. Anna Gunn only speaks one line in this episode.
4. When Walt and Mike are sat in Mike's kitchen, on the refrigerator door behind Walt can be seen a piece of paper written on in crayon saying 'Blue is Good' 'Yellow is bad' in their respective colours. Green is also shown, but partly obscured by Walt ending in "is nice". These colours and their associated themes run through the entire series.
5. Jesse refers to the RV as The Crystal Ship. This is also the name of the magazine Malcolm's high school publishes in the episode "Dirty Magazine" on Malcolm In The Middle.

Hazard Pay

1. In one scene Walter and Walt Jr. are watching Scarface (1983), a movie that features two guest stars on the show: Steven Bauer (Don Eladio) and Mark Margolis (Hector Salamanca).
2. Charles Baker (Skinny Pete) can really play the keyboard.
3. This episode showcases the only meeting between Mike and Huell, as well as a brief path-crossing between Mike and Skinny Pete / Badger.

Fifty-One

1. Within this episode Walter replaces both his calculator watch and 2004 Pontiac Aztec, which were integral parts of his representation as a mild-mannered suburban school teacher. The respectively sleeker models they are replaced with, and the recovery of his signature pork pie hat, symbolize his final consumption by the Heisenberg persona.
2. First time Walter sits in the boss chair.
3. In the end of the episode, Skyler uses a mug for an ashtray. On the mug is printed the number 51, the same as the title of the episode which presumably relates to Walter's 51st birthday.
4. The TAG Heuer Swiss chronograph watch that Jesse gives Walt for his birthday is the reissued "Monaco" model popularized by Steve McQueen in Le Mans (1971).
5. This episode takes place on September 7, 2010, exactly one year from the events of the pilot.
6. When Skyler mentions sending Walt Jr to a top rated boarding school in Northern Arizona, she is most likely referring to Verde Valley School, near Sedona, Arizona.
7. Skyler doesn't speak for the first 10 minutes of this episode.
8. Near the end of this episode, Walt says, "The methylamine keeps flowing no matter what. We are not ramping down.... Nothing stops this train." That foreshadows the train sequence in the next episode.
9. The ending scene of the episode with Walt's watch ticking is a metaphor for his time is running out.

Dead Freight

1. During the scene where Walt bugs Hank's office, the same model of lamp that was bugged by the FBI in The Sopranos (1999) is visible on Hank's desk.
2. The railway pass where they hide the empty methylamine barrels for the heist appeared also on the 2008 movie Appaloosa, when the train is stopped and the main characters aim at Renee Zellweger captors.
3. When Hank asks Walt if Skyler is going to therapy, he answers that she's going with a man named Peter, though he couldn't remember his last name. At the same time, on the credits, the name of Peter Gould, co-executive producer of the episode, appears.
4. This episode refers to "dark territory" that the train passes through. Jonathan Banks appeared in Under Siege 2: Dark Territory as one of the terrorists who takes over the train in "dark territory."
5. Hank asks Walter Jr. if he wants to watch the movie "Heat". "Heat" is a film about men pulling off a heist, but miss one factor that could potentially lead to them getting caught. Walter and Jesse do the same thing with their train heist, the killing of the kid on the bike being the one factor missed.
6. On the opening scene with the young boy on the dirt bike, after he has put the spider in the glass bottle, you can faintly hear a train's horn in the distance. This is the train that Walt, Jesse and Todd steal Methylamine from.
7. After Todd has shot dead the young witness on the dirt bike, the camera lingers on the bottle containing a captive spider dropped by the murdered boy. The image of a spider in a bottle is metaphorically used by Queen Margaret in Shakespeare's tragic play to describe the scheming and ruthlessly homicidal Gloucester (who later becomes the titular Richard III). It is an equally apt metaphor for Walter White's thoroughly malevolent character. "Why strew'st thou sugar on that bottled spider / Whose deadly web ensnareth thee about?"

Buyout

1. Skyler and Jesse's first encounter since Breaking Bad: Cat's in the Bag... (2008)
2. During a TV newscast, it is revealed that the missing boy's name is Drew Sharp.
3. In the scenes before the opening credits roll, after the boy and his motorcycle are "barreled": Jesse (Aaron Paul) is standing next to a white tanker truck, lighting and smoking a cigarette. The light bouncing off of the tank makes the buzz-cut hair on the side of Jesse's head look grey, as though this lifestyle is prematurely aging him.

Say My Name

1. Walt says to Todd as he begins to teach him how to cook meth, "I don't need you to be Antoine Lavoisier". Antoine Lavoisier is known as "the father of modern chemistry".
2. The working title for this episode was "Everybody Wins".
3. For the scene in which Mike dies, the crew members wore black clothing or black armbands to symbolize their mourning for the loss of Jonathan Banks as a cast member.
4. In an interview after his character Mike Ehrmantraut was murdered by Walter White, Jonathan Banks said the underlying story was that Mike was going to leave the U.S. for good and head to a small house he'd purchased long ago on the coast of Spain. Banks said this was because in real life he and his wife have purchased exactly that kind of retirement villa to live in once he decided to retire from acting for good, and in fact he was leaning towards doing this before being offered and accepting the role to return as Mike in the Breaking Bad prequel series Better Call Saul (2015).
5. The river where Mike dies is the same river into which Hank threw Tuco's grill.
6. In the scene where Dan Wachsberger (Chris Freihofer) is in the bank, the safety deposit box for Mike's granddaughter Kaylee is 603. 603 is also the area code for New Hampshire where Walter later flees to towards the end of the series.

Gliding Over All

1. Walt tells Lydia to "Learn to take yes for an answer." This is the same advice that Mike gave Walt in Breaking Bad: Thirty-Eight Snub (2011).
2. When Walt first approaches Jack and his men to kill Mike's men within a span of 2 minutes, Jack jokes along the lines that "killing bin Laden was easier than this." The show's timeline spans exactly 2 years, beginning in 2008. Osama bin Laden was killed on May 1, 2011. Vince Gilligan later admitted that this was a mistake.
3. When Walt is meeting with Jack and his gang, he notices a painting on the wall and wonders if he has seen it before. It is a copy of the same one that was in his hospital room in Breaking Bad: Bit by a Dead Bee (2009).
4. At the conclusion of Walt and Lydia's meeting, Lydia shakes Walt's hand and declares, "We are going to make a lot of money together." This line is nearly identical to what Tuco Salmanaca told Walt in the season 1 finale Breaking Bad: A No-Rough-Stuff-Type Deal (2008).
5. In the American legal system "queen for a day" refers to written documents that are designed to create a potential mutually beneficial arrangement with the federal government and a person of interest regarding a criminal investigation. The concept of a "queen for a day", more commonly known as proffer agreements permit the accused individual to disclose to authorities key points of knowledge to crimes committed by that person and/or others, with implied assurance that said knowledge will not be used against them in later proceedings.
6. The mid-season finale of the series.
7. This is the last episode of the fifth season of Breaking Bad to air in 2012. The series would not resume airing its fifth season episodes until almost a whole year later in 2013.
8. The title refers to "Gliding O'er All," a poem in Walt Whitman's "Leaves of Grass." The five-line poem concludes with the line, "Death, many deaths I'll sing." Ten people are murdered in this episode, with another probably poisoned.
9. Walter White's last episode cooking meth.
10. The book that Hank finds in Walt's bathroom is a copy of "Leaves of Grass" by Walt Whitman. The inscription inside, written by Gale, reads: "To my other favorite W.W. It's an honour working with you. Fondly G.B."
11. First appearance of Uncle Jack.
12. During Walt and Lydia's meeting he asks her if she thinks once she hands him the list of names that he will murder right there in the restaurant. In the series finale in this very same restaurant is where Walt poisons her with the ricin, leading to what would be her death.

Blood Money

1. The first episode to the second half of Season 5 is dedicated to Kevin Cordasco, a teen Superfan of the show who died of cancer in March of 2013. Before his death, Kevin was able to meet Bryan Cranston, Vince Gilligan and other prominent members of the Breaking Bad family and he was even offered the chance to read the final scripts of the series so he would know how the show ends. Kevin declined as he didn't think he could keep the secret.
2. Third episode directed by Bryan Cranston following Breaking Bad: Seven Thirty-Seven (2009) and Breaking Bad: No Más (2010).
3. Premiered almost a whole year after the previous fifth season episode: "Gliding Over All."
4. Badger describes to Skinny Pete his fan story involving a partial body transport. However, due to the Heisenberg uncertainty principle, the transporter contains a Heisenberg compensator. This is probably a self-reference to the Heisenberg character.
5. Immediately after Hank discovers that Walt is Heisenberg, as soon as he opens the porch door to rejoin the family you can hear Marie say to Walter "You are the devil."

Buried

1. Following comments in this episode about ending DEA agent Hank "on a trip to Belize" - meaning murder him - the Belize Tourism Board actually offered free vacations to Vince Gilligan and eight of the shows's cast as PR stunt to help confirm the Central American country's image as a safe spot for tourists.
2. Jesse Pinkman (Aaron Paul) does not have any lines in this episode.
3. The location where Walt buries the money (34º 59' 20" N, 106º 36' 52" W) is actually the location of Alburquerque Studios, where the series is filmed.
4. The shootout between Jack's crew and Declan's men was originally meant to be on screen, but due to the budget for the To' Hajilee shootout and the M60 shootout it wasn't.

Confessions

Rabid Dog

1. When Jesse walks past a book case into the Schraders' living room to tape his confession, a DVD copy of Deadwood: The Complete Series is seen on the book case. Anna Gunn, who plays Skyler White, the wife of the main character on Breaking Bad, also appeared on Deadwood as Martha Bullock, the wife of the main character on Deadwood.
2. When updating Walter on the search for Jesse, Patrick Kuby states he put a bug in Badger's mother's house only to hear him talk about Babylon 5 (1994) for three hours. Bryan Cranston actually made a guest appearance in the episode Babylon 5: The Long Night (1997). He portrayed Ranger Captain Ericsson.
3. First time Jesse and Marie meet in person.
4. Among the books on Hank Schrader's bookshelf are the titles "Rainbow's End," "The Final Days," "The Money Harvest," "Big Secrets," "Mad Money," and "The Blue Nowhere."
5. The DEA coffee cup that Marie hands to Jessie spells out "DEAD" if you include the cup handle as the second "D".

To'hajiilee

1. To'hajiilee is the Native American reservation where Walt buried his money and where he first cooked meth.
2. To'hajiilee is a noncontiguous section of the Navajo Indian Reservation, located in New Mexico. The word comes from the Navajo phrase tó hajiileehé, meaning "where people draw up water by means of a cord or rope one quantity after another."

Ozymandias

1. In an interview, director Rian Johnson revealed that baby Holly's saying "mama" in the scene where Walt changes her was unscripted. The scene was written to have Walt simply look at Holly and decide to give her back. However, the baby's mother was on set behind Bryan Cranston, and the baby started saying "mama" while they were filming. Cranston simply went along with it and the shot ended up in the episode.
2. While rolling the remaining barrel of cash, Walt passes the same pair of pants that he lost in the pilot.
3. The flashback of Walt and Jesse at the beginning of the episode was the final scene that was shot for the series.
4. Guillermo del Toro desperately wanted to direct the episode "Ozymandias". When he expressed this desire to the episode's eventual director Rian Johnson, Johnson responded, "Yeah, sorry, I'm the one who gets to f*** the prom queen."
5. Series creator Vince Gilligan said in an interview that, "Ozymandias is the best episode we ever have had or ever will have."
6. This episode is considered by many television critics and audiences to be the greatest episode of TV ever produced. It received universal critical acclaim, is the highest rated TV episode on IMDb and won three Emmys for Best Writing, Best Actor, and Best Supporting Actress.
7. Vince Gilligan requested, and received, permission to not show the traditional opening cast and crew credits until over 1/3 of the episode was shown, because he felt the titles would take away from the shock and horror of the events that were shown (both the flashback to the first time Walter White and Jesse Pinkman cooked meth in the desert, and in the moments after the shootout between Hank, Gomez and Uncle Jack's gang).
8. The episode's title gets its name from the famous poem by Percy Bysshe Shelley which alludes to a crumbled empire. Bryan Cranston read the poem in a promo for season 5B.
9. The knife Skyler picks up is the exact same one that Walt uses in season two, fearing that Tuco would come to the house.
10. There was another director attached to helm this episode, but when he/she couldn't do it, Vince Gilligan quickly got in touch with Rian Johnson, who had expressed the desire of doing another episode before the show was over.
11. The only TV show episode that has had a 10/10 user rating for more than a year. (3 and a half years it maintained this rating) and is still the highest rated episode of all time.
12. The fire station that Walt leaves Holly at is actually five miles north of the actual White residence.
13. In the fire station, we see someone move the white king piece in a chess game. In chess, moving the king is a method of (temporarily) avoiding a loss when the player is under direct attack. Although this episode's title references a fallen king (Ozymandias), this chess move symbolizes that Walt (the white king!) prevented his own downfall and that he isn't finished just yet.
14. There are many visual callbacks to previous episodes in this one: Walt's shocked, agonized reaction to Hank being shot is identical to Gus's shocked, agonized reaction to the shooting of Max in episode 4.08, "Hermanos"; Walt sees the pair of pants that he lost in the desert in the Pilot; Skyler's accusation that Walt killed Hank is nearly identical to her telling him, "I fucked Ted" in episode 3.03, "I.F.T."; Jesse's beaten, pulpy face is similar to Gus Fring's face at the end of "Face Off"; After his call to Skyler, Walt breaks his phone in half exactly like Gus Fring did in episode 3.08, "I See You."

Granite State

1. This is the only time in the entire series where the show's full theme song is played in its entirety.
2. The final phone call between Walt and Walt Jr. had to be filmed a second time because the original production footage was destroyed during shipping as the film canister fell out of the containing truck and was crushed by a 737.
3. The Extractor (Ed) runs a service providing people with new identities under the guise of a vacuum cleaner repair shop. This role was played by Robert Forster, who once worked as a vacuum cleaner salesman while struggling as an actor.
4. On the night that this episode aired (September 22, 2013), the series won the Emmy for Outstanding Drama Series for the first time. Anna Gunn also won Outstanding Supporting Actress in a Drama Series, also her first.
5. During the interview with Gretchen and Elliot about their Nobel Prize, Charlie Rose mentions a column written by New York Times columnist Andrew Ross Sorkin. The column condemns the actions of the Schwartzes' generous charity for New Mexico drug abuse victims as an attempt to white wash the recent news that surfaced that Walter White may have been the co-founder of Grey Matter Technologies. The Schwartzes instead tell Charlie Rose that the only thing Walter White had to do with the co-founding of Grey Matter Technologies was coming up with the name. In real life, this column was actually written, and an excerpt appears on the New York Times' website.
6. The drink that Walter White orders at the bar is called a Dimple Pinch. It's a rare, 15 year aged form of Scotch Whiskey produced by one of Scotland's oldest surviving distilleries.
7. Robert Forster's character name is never mentioned within the episode. Various press materials reference him as The Extractor or The Disappearer. The name 'Ed' is found in the plot synopsis for this episode on AMC's official Breaking Bad website.
8. The outdoor mountain scenes that take place in New Hampshire were actually filmed in the Sandia Mountains of New Mexico.
9. When Saul Goodman gets a new identity from the Extractor, a monitor shows his new ID from Nebraska. Saul asks whats in Nebraska and the Extractor says: "You." Bob Odenkirk who plays Saul Goodman also plays a role in the Movie Nebraska (2013).
10. Michael Bowen and Robert Forster both previously costarred in Jackie Brown (1997)
11. Vince Gilligan had difficulty figuring out how to get Walt out of hiding until Kevin Cordasco, a devout Breaking Bad fan with terminal cancer, suggested that the Schwartzes be re-introduced and for them to claim that Walt had nothing to do with the creation of Grey Matter Technologies. Sadly, Cordasco died before getting to watch the episode and the finale of the show. Gilligan even offered to reveal to him how the show would end but Cordasco refused saying "No spoilers, man."
12. Saul tells Walt that with any luck in a month he would be managing a Cinnabon in Omaha. In the opening scenes of Better Call Saul (2015), he is indeed managing a Cinnabon in Omaha.
13. The scene where Skyler talks to the federal agents is presented in a nearly identical fashion as the scene from the pilot with Walter's diagnosis.

Felina

1. The apparel Walt wears when he arrives at the compound is identical to what he wore in "Pilot". He begins and ends the series in the same clothes.
2. There was one scene cut from the final script for budget and time reasons. It took place after Walt makes the call in which he pretends he's the Times reporter. In it, a former student of Walt recognizes him. Walt pays him off and threatens him to make sure he doesn't rat him out. But before leaving the former student, he asks, "What kind of teacher was I?" The former student replies, "You were good" and then says he remembered the time Walt sprayed different chemicals at a flame and it made different colors.
3. "Felina" is the name of the woman in Marty Robbins' song "El Paso," which is played in the car Walt steals from New Hampshire. In the song, the singer is driven from El Paso for the crime of murder. He eventually returns, only to be gunned down.
4. The last episode of Breaking Bad is episode #62. The 62nd element on the periodic table is samarium, which is one of the primary drugs used in treating lung cancer.
5. The episode name when broken into elements found on the periodic table are Fe (iron), Li (lithium), and Na (sodium.) With these elements is a play on the popular phrase "blood, sweat, and tears" with "blood, meth, and tears." The title is also an anagram of "finale".
6. The Badfinger song "Baby Blue" saw a nearly 9000% increase in online streaming and largely increased sales on iTunes, topping nearly 50,000 downloads since the finale aired. [07 Nov 2013]
7. This episode was watched by 10.28 million people on its premiere night, up from the previous high, "Granite State", which had 6.58 million. This makes "Felina" the most watched episode in the series' history.
8. Vince Gilligan said he couldn't bear to directly watch Walt and Skyler's last scene together because it was so emotional for him.
9. A comedic sketch was filmed as a DVD bonus depicting an alternate ending where Bryan Cranston reprises his role as Malcolm In The Middle's Hal. He wakes up next to his wife Lois (Jane Kaczmarek) and begins describing the horrors of the Heisenberg empire, and at one point begins referring to Lois as Skyler. The scene ends with him attempting Heisenberg-style love making and Walter White's trademark black hat appears on the chair next to the bed. This scene was leaked on YouTube before the final DVD set was released.
10. The amazing shot of Skyler reflected in the microwave was completely accidental. Gilligan admits not knowing he got it until the editor complimented it.
11. Walt's last words (on the phone with Lydia) mark the only time in the series that he ever ends a phone call by saying "bye" instead of just hanging up. Ironically, he doesn't hang up, but tosses the phone instead.
12. Vince Gilligan credits the 1956 John Wayne film "The Searchers" as being the inspiration for the final standoff between Walt and Jesse.
13. After several prominent TV speculated post-series finale that they felt/hoped that the events of "Felina" were actually a dying vision by Walter White as he succumbed to his lung cancer without ever getting out of his exile area in New Hampshire, creator Vince Gilligan publicly said that the events of the finale were part of the show's reality. Gilligan noted that several key events in the finale would not make logical sense unless Walter had returned to Albuquerque to find them out, particularly involving the actions of Jack and his Nazi gang, Todd, and Lydia.
14. As Jesse is having the hallucination of him making wooden boxes is a reference to an episode earlier on when he was at one of his drug classes was what he told the group leader his "dream job" would be.
15. Walt's New Hampshire license plate (3272153) adds up to the number 23. October 23rd is an unofficial holiday for chemists known as "Mole Day" and was created by a high school chemistry teacher to get students to enjoy chemistry.
16. While Vince Gilligan's famous comment about Walter White's journey on the show ("We're going to take Mr. Chips and turn him into Scarface") was usually translated in simple terms of a teacher (Walter White/Mr. Chips) turning into a murderous drug kingpin (Heisenberg/Scarface), Gilligan said that the "Scarface" reference had to do with Walter becoming genuinely evil and not fulfilling his original plan to make money from selling meth for his family without being part of the drug world's brutality. Gilligan said "If you're going to be Scarface, you have to BE Scarface all the way down to your core...otherwise you're just pretending to be Scarface."
17. Jack's death mirrors Hank's - as Hank was shot by Jack as Walt offered Jack all his money to spare him, Jack is shot by Walt attempting to offer Walt his money back to spare him. They were also both shot in the head mid sentence.
18. Despite ricin being a recurring element throughout the show Lydia is the only person to have been successfully killed with it. The attempted poisoning of Tuco Salamanca was sabotaged by Tio Salamanca, Brock was poisoned by a plant of Walter's house (although Jesse thought it was ricin) and Jesse never used it on Gustavo Fring.
19. Near the end of the episode, Walter White checks the current meth cooking installation. One of the gauges he looks at sports the brand name "Weiss", which is German for "White".
20. The main reason why Walt left his watch at the gas station was because in the ending scenes he didn't have it on. To prevent this from being a continuity error, Walt had to leave the watch behind.
21. When the series finale was over, several critics who openly expressed unhappiness at the relatively positive resolution for Walter White (he blackmails the Schwartzes into a plan to get his money to Flynn, Skyler doesn't turn him in to the cops and he provides information for her about Hank and Gomez to trade for charges being dropped against her, he kills Jack and his entire gang, Lydia is fatally poisoned with ricin, Jesse doesn't kill him when he has the chance, and he dies just before the cops arrive at the Nazi compound due to a fatal stray bullet) and speculated that "Felina" was actually a dream sequence where all of the "good" news for Walt was hallucinated by him as he died of a heart attack near the end of the "Granite State" episode. Vince Gilligan made his annoyance clear by not only stating that "Felina" was NOT a dream-based episode but pointing out several story threads that would have made zero sense in such an episode (including the fact that Lydia had begun meeting with Todd to discuss the blue meth business in Walt's absence).
22. In the final scene as the camera pulls back you see the lab Walter is lying in is framed by iron bars giving it the same shape as the RV where he and Jesse began cooking.
23. Lydia's death mirrors that of Emilio's (both were poisoned), while Walt's death mirrors that of Mike Erhmantraut (both were shot in the side and die peacefully).
24. Walt dies at age 52. This is the same age that Bryan Cranston started playing Walt at the beginning of the series.
25. After Walter falls to the ground at the very end, you can see on the tank where his hand was a "W" left in blood. This symbolizes the main character's name "Walter White", and his final signature.
26. The device Walt used to control the M60 is a Chinese made UN-4001 Central Car Lock System, a remote-controlled central car lock. The letters UN on the box is covered by a bar code sticker but largely uncensored. It is the only Chinese product in the show to be shown as Chinese. Statistically, it is the most commonly used remote car lock in China.
27. At the beginning of the episode, when Walt is in the car, when he finds the car keys they have a Narcotics Anonymous keychain on it, ironic for a drug kingpin.
28. Walter White's final act of revenge is very similar to Gustavo Frings act on Don Eladio. Both Don Eladio and Jack Welker killed men they were close to, both were spared, and both came back into their enemy's headquarters to execute their plan.
29. Jesse Plemmons (Todd) played Ed Blumquist on Season 2 of the FX mini-series Fargo; at one point in the season, Ed nearly dies from strangulation just as Todd does.
