The theory states that the pool represents Walt's hubris (the pool does not fit the house and the hubris does not fit the chemistry teacher) and that quite a few bad decisions were made around the pool (poisoning Brock for one) as Walt became darker and darker.
He also had a habit of staring in the blue waters of pools as he contemplated his life since turning 50. Oddly enough, the pool was never used by the White family for fun. If they did, it wasn't shown during the events of the series.
The Pink Teddy bear is an object from Wayfarer 515, the plane which crashed onto another in the air near Walter White's house. Seconds after the crash, the bear landed in Walter's pool. As a result of the plane explosion, the pink bear lost an eye and sustained a burn to its left side.
The first time we see Walter wearing green is in the pilot, when he takes off his beige color and dons a green apron. In essence, he's stripping away his old life and adorning himself with the color that will symbolize everything that will transpire in the seasons to come. It's his first step to becoming Heisenberg.
Gilligan uses the development of Walt's narcissistic personality disorder as he gains more money as an allegory for those in society who are wealthy yet continue to be selfish. American Psychiatric Association.
Hank is orange, which sits between yellow and red. This means he is both associated with the meth business and the violence that comes with it. He is the opposite of Skyler's blue, because while Hank wants to bring down Walter's meth empire, Skyler eventually becomes a major part of it.
Television critic Myles McNutt has called it “a reminder for Walt – a symbol of the damage he feels responsible for.” But when Gilligan was asked about it, he said “the teddy bear eyeball that Walt found in his swimming pool is symbolic.
After Skyler breaks into Walter's apartment, she finds the plastic eyeball of a teddy bear that has been part of the series since the second season. The eye has long been used as a symbol to identify Walter's gradual descent into a life of crime, and Skyler's discovery of it symbolizes her own similar descent.
Flies (Diptera) are common insects that appeared in Breaking Bad. It has been speculated that the fly represents guilt, contamination, irrational obsession, and the loss of control in Walter White's life. When a fly gets into the superlab, Walt embarks on an obsessive quest to destroy it ("Fly").
Following Fring's death, Skyler becomes terrified of Walt, as well as the prospect of going to prison as his accomplice. She breaks down in front of Marie at the car wash and falls into a deep state of depression.
Skyler White
We've established that blue represents purity, and Skyler is at her purest at the start of the show. She's not aware of Walt's business or even his cancer, and when she starts covering for him, she starts to wear less and less blue.
In “Cornered,” Skyler White drives to the Four Corners with her infant daughter and flips a coin, presumably in an attempt to decide which state to flee to as she contemplates leaving Walt. The quarter settles in Colorado both times she flips.
Cranston told Here & Now's Robin Young that the men crawling on the ground are worshippers of Santa Muerte, a dark off-shoot of Catholicism. "The Santa Muerte is a deity that does not discriminate on what your prayers or wishes are," Cranston said.
The team from MythBusters (2003) tested the science of this scene and found that, while the chemicals and applications used in the episode did cause some dissolving (they used a pig carcass in the test), it would not be able to dissolve an entire human body nor destroy the bathtub and floorboards.
They are visiting a shrine of Santa Muerte (Saint Death). In Mexico, she is a popular folk saint/deity who is the patron saint of (among other things) drug dealers and smugglers, and is often invoked to protect against violent death. Traditionally, a worshiper would crawl on his knees on his way to visit the shrine.
Jack Welker (Michael Bowen) is the leader of a neo-Nazi gang and the most evil Breaking Bad character. He is a man who is motivated by the moment. He may seem like a man motivated by money, but he is motivated by pride and pleasure.
During the original series run, Cranston shaved his head to play White, who is diagnosed with cancer at the beginning of the show and loses his hair during chemotherapy. But because Cranston didn't have time to shave for El Camino, he was instead fitted with a bald cap.
By the end of the episode, the boy's father has been killed by his mother with a stolen ATM before she passes out, completely strung out on meth. Before fleeing, Jesse makes an anonymous call to the police, knowing that the boy will be saved by child protective services.
It is later revealed that the teasers actually depict the aftermath of the mid-air collision of the Boeing 737 commercial airliner Wayfarer 515 and the charter plane JM21 ("ABQ").
They needed the food to remain on Walt's roof for the sake of the plot, and an unsliced pizza was the only way of managing that. "A thrown, sliced pizza would come apart due to centrifugal force or angular momentum (or something like that)," explains Gilligan in response to the question (via Reddit).
Purple. In Breaking Bad, Purple is primarily worn by Marie and it is used to symbolize protection, self-deception, and complete lack of involvement in the meth trade. Marie often wears the color purple to show her self-deception. Throughout the show he often tries to convince herself that she is somebody that she isn't ...
It's revealed in Season 5 that Ted ended up hospitalized with severe neck trauma. He has to keep his head in a huge protective brace and his head was completely shaved.
Throughout the series, Marie is almost always shown wearing the color purple, which creator Vince Gilligan explained is symbolic of her being misled; for example, Walt and Skyler were deluding Marie about who was behind the drug business.
