Walt is one of the five original Main Characters still alive at the end of the series. Walt is also one of the few confirmed Oceanic Flight 815 survivors by the end of the series, along with Zach, Emma, Kate, Sawyer, Claire, Aaron, Hurley, Cindy, Rose, Bernard and Vincent.
Walt returned to Lost in "The Life and Death of Jeremy Bentham", when Locke visits him in New York. Kelley had stated a willingness to return to the show again, which was realized in "The New Man in Charge".
Yes, Walt used his special ability and appeared to Shan. But he didn't lead her to Ana Lucía. He wanted Shannon to be quiet and not be killed.
Walt is "special" because his body and mind both travel time as opposed to Desmond who has only traveled with his mind. Walt has some influence/control over electromagnetic fields.
Michael and Walt are given a boat and coordinates to freedom, and they sail away from the Island. A flashback during "Meet Kevin Johnson" reveals that they manage to return to New York City, where Michael hands Walt over to Walt's grandmother.
On her own momentarily, Shannon heard the whispers moments before Walt appeared nearby in the trees. Walt was dripping wet and speaking backwards: "Don't press the button, button bad." On rushing back, Sayid found Shannon on the ground, but Walt had vanished.
When Michael thought that he talked to Walt over the computer, he was actually talking to one of The Others. In the promo for 'Secrets of Lost', a Blu-Ray special feature, Damon Lindelof confirmed that it is Walt, on the other side of the computer.
Ultimately, of course, Walt's secret is exposed to everyone - even the scared lady next door. Walter White becomes an infamous name and the man himself is forced to go on the run. However, the unraveling of Walt's secret is a gradual process.
Perhaps this is why Marie discovering the truth about Walt happens off-screen. Even though the audience don't see the moment Marie finds out, it can be inferred that Hank tells her during the season 5 episode “Buried.” Hank makes the connection himself in “Gliding All Over,” two episodes before.
There are only 6 survivors of the middle section that are alive, Walt, Sawyer, Kate, Claire who left the island and Rose and Hurley who stayed on the island, and a maximum of 14 survivors of the tail section that are presumably still alive including Bernard, bringing a grand total of 20 survivors of Oceanic Flight 815 ...
'Breaking Bad' Season 5 Recap — Hank Arrests Walt, Gunfight Erupts | TVLine.
Even as her marriage crumbles, Skyler permits Walt to take care of Holly and defends some of his actions to her lawyer, who advises that she leave Walt immediately. She later finds that Walt has signed off on their divorce and left the house for good.
In the end, Hank's body was returned to his family and Walter was killed after seeking vengeance on Uncle Jack.
When her life fell apart and Walt disappeared, Skyler lost her assets and moved in with her kids in a small apartment with a job as a taxi dispatcher. It was revealed that her sister, Marie, reached out for a truce, so it's likely that the two reconnected shortly after the series finale.
After Hank is killed by Jack Welker, she is initially unaware of his death and reconciles with Skyler on the condition she tells Walter Jr. everything. Marie learns that Hank is missing when Walt kidnaps Holly, and eventually receives confirmation he is dead.
In the final scene, Hank figures out that Walt is Heisenberg while perusing Walt's copy of “Leaves of Grass” on the toilet.
Because moments before, Hank (Dean Norris) arrived on the scene, having tailed the kid himself, and he manages to talk Jesse down and encourage him to cooperate, so they can both bring down Walt together. How? By Jesse turning snitch.
While Walt is trying to wake Jesse, he inadvertently and unknowingly knocks Jane onto her back; she starts to choke on her own vomit. Walt rushes to help, but then after hesitating for a moment, lets her die in order to protect Jesse from their eventual overdose, and for self-preservation since she threatened to expose ...
After insisting for five full seasons that everything he did, he did for his family, Walt finally confesses that all of his actions were entirely self-motivated.
He appeared to have telepathic control over animals, polar bears included. Many of the early plots centered around Walt being in danger or having gone missing. But then Kelley hit a growth spurt, and he was effectively written off the show in Season 2, not to return until Season 5.
A plot twist: Ben tells Sawyer they are actually on a second Island that was previously unknown to the survivors.
Dirty Water: Guilt and Contamination
And in Breaking Bad, the Whites' swimming pool is a mirror reflecting Walter's emotions at any given point. Most saliently, Walter's relationship with his pool visualizes his obsession with contamination which is a stand-in for his guilt over what he's done.
Although it took some viewers (including this one) a while to catch on, most everyone agrees that Walt's call to Skyler was intended for the police he knew would be listening, that in casting her as a terrified woman under the thumb of a homicidally violent drug kingpin, he was trying to exonerate her, to absorb her ...
In it, DEA agent Hank, wounded after a shootout with a murderous band of neo-Nazis, refused to beg for his life (despite his brother-in-law Walt's pleas) and told Nazi leader Jack to “go f–k yourself” before taking a fatal bullet.
