1. What Skyler wants? Inclusion.
What happens to Skyler? Absolutely nothing. She gets trucked away to New Hampshire to live out her days. Ever inserting herself into the action, she gets removed from the action. If she had testicles, I’d say she gets neutered. She gets relegated to the powerless lied-to role that she so hates.
2. What Hank Wants? Dominance.
Speaking of neutered . . . Hank is a tunnel-visioned scumbag cop who deserves nothing less than impotence. Remember Marie jerking him off? Remember how his life came back to him once he achieved a hard-on? Not this time. Hank is neutered, unable to do anything at all, which, for a macho Hank, is a fate worse than death.
3. What Marie Wants? To Punish.
She of the skillful jerking? She of the hard slap? She who tries to steal babies from their cribs? She dies. With the White family gone to New Hampshire, she has no one to punish. Jessie is the only target. She kills him (via poison?) Walt slips her the ricin.
4. What Jessie wants? Normalcy.
Jessie wants to do the right thing. He wants to right his wrongs. He wants to atone. He never gets that chance. He thinks he is doing the right thing by surrendering to Hank, but Marie, with no other target since the Whites have absconded, kills him.
What else could bring Walt back from New Hampshire, the trip from which he can’t come back, to seek his revenge? The White family dissolves, and Marie poisons Jessie, killing him. When Walt learns of this, the revenge plot comes into focus.
You see, the only thing that cannot be done is harm to Jessie. That is the only thing that Walt will absolutely not tolerate. Jessie’s death is the only thing that could bring Walt back. This is my most significant contribution to Breaking Bad theory: Marie kills Jessie. Jessie’s death is the impetus for Walt’s return. Marie gets the ricin.
5. Walt Jr.? His role-model. His amazing father.
Don’t fall for the Walt Jr. theories. They are diversions. Walt Jr., like all of the White clan, lives on in New Hampshire. Walt Jr. learns the ugly truth about his meth-cooking, murdering father, which crushes the father/son relationship. This adds up. Keeping the truth from Walt Jr. has occupied so much of the show’s narrative that we have to see Jr. learn the truth. Nothing else will satisfy, nor be as crushing to Walter White.
6. The Neo-Nazis? Money.
Machine gun. Walt wipes all of them out with the machine gun. Walt recovers the Methylamine.
7. Heisenburg? Walter White wants his efforts to add up to something.
Walt wins. He always wins. He has to win. Only, he wins nothing. At this point, there is nothing left to win. His family ties irreversibly severed (no more son to father, no more wife to lie to) all of his enemies either neutered or dead, he goes right back to what he knows. He returns to what he can do better than anyone else.
Walt ends the show by cooking up one more batch of meth.
