Walt is not stupid, which is why he is not going to take ricin, thus a slow and agonizing death.

As Walt said "some day you're going to come in and find me dead." There will likely still be plenty of money when that day arrives.

Walt was ready to turn himself in, as living in isolation in the mountains was even worse than actual prison and he finally realized his pipe dream of leaving his money to his children was futile. Then he realized, with nothing left to lose and not far from death anyway, might as well finish his unfinished business.

And neighbor lady shat her britches.

Well we know Saul's going to have a spinoff, unless that's a red herring to distract us from his real fate…

I wonder if the final confrontation will be Walt reclaiming the money the Nazi gang stole from him after killing his brother in law, even as they continue to profit from his recipe and did not finish the Jesse job as promised either. Maybe he finds out when Jesse escapes and hunts Walt down but Walt kills him first?…

Easy. The family goes into witness protection and the house is abandoned. The neighbor lady in the flash forward obviously knows about Walt so obviously it was a big news story. House become infamous and teenagers and squatters ransack/vandalize the place.

Hank got shot at least twice…

I know I'm just being a contrarian, but being a member of a White Power prison gang doesn't make one inherently a black-lynching, pro-Holocaust bigot. Convicts and criminals of all races and prior ethno-philosophical beliefs join race-biased prison gangs to protect their own ass and intimidate rival gangs that…

I dunno… Lots of scary meth lab chemicals = possible escape plan/horrific death for Todd.

Last scene of Breaking Bad will be an unrecognizable starved 150 lb Huell.

In addition I bet the Nazis already broke into Hank's house and stole Jesse's tape, so the pleas of Marie will be all that's keeping Hank and Gomie from looking dirty as hell.

Uncle Jack redeemed all his evil deeds by letting Walt keep a barrel of his own money. What a swell guy.

BS. Jane killed her damn self by ODing on heroin. Walt had zero responsibility for her fate, and she gave him no reason to give a fuck either. I don't defend Walt's actions most of the time, but Jane's death was her own fault. Had she lived, Jesse might have been long dead by now because she led him into a junk habit.

Q: What did the Stalin say when Germany invaded Poland?

Agreed. This sounds most plausible. Marie brings Walt down by tipping off the DEA about everything she knows and the tape if she has it. The problem for Walt - he either has to get the Nazis to dig up his money now or risk it being found by the DEA in the crime scene investigation.

Marie knows. When Hank doesn't return, she goes to the DEA with Jesse's video.

If I'm Walt, I hire the Nazi gang to kill Hank and Marie in front of the family and then have Saul's guy on the ready to convincingly pretend to be a witness protection relocator. This gives a logical reason to explain to Jr why they have to uproot everything, move across country and assume a new ID. But that's just…

The Reagan bio was obviously ironic.

Yes, but has he submitted Walt's copy of "Leaves of Grass" as evidence yet? That is the only thing Hank has that physically connects the dots outside of all the theories and connections in his head. If Hank is killed and the book disappears in a house fire, Walt probably won't be caught or even suspected by the DEA…
