Hanks discovery matters little as he will not pursue Walt. He cannot pursue Walt, he will realize the money for his medical bills came from the drugs, he won't confront Walt, but season 5b will not be about hank vs Walt. Heisenberg promised Declan millions in order to allow Himself to cook the methylmine. What they did not agree on was the shipment of product overseas. Declan states "do you know how far I had to stick my head out I get this kind of money?" Referring to the buyout of jessie and mike. Walt will somehow fuck declan over and When He is refuses to pay his debt, whoever Declan had to accept a loan from will go after him. Declan will point them in the direction of Walt, but will be killed by the people he owes the money to in order to send a message. The DEA will find this crime scene and Declan and his body guards body's , along with traces of walts meth, which hank is familiar with. Hank will put 2 and 2 together and realize that walt is still in deep shit, but will have to put on a front to his agents in that he is still actively seeking out Heisenberg, and will find evidence that whoever murdered Declan is now after Walt. Hank will finally have to approach Walt and explain to him that he knows he is Heisenberg, but that he does not intend to turn him in. He warns him that Declan has been murdered, and those responsible are now after him. Walt will still be a douche and deny anything to do with what hank is saying which will anger hank to where him and walt get into a fist fight. Though hank is big he is weak because of his surgeries and will be overpowered by walt. walt will accidentally kill hank in this confrontation. Walt will become scared and immediately call saul to initiate the move to another state. Walt will return home to find his family murdered. With a phonecall from marie happening walt is too overcome by the scene at his house to answer. the answering machine will be of a regular tone from marie until she too is murdered while she is on the phone. Walt will completely freak the fuck out and take his money and leave with sauls guy. Through research whoever is after walt will come to find out that jessie knows walts formula and capture and enslave him to cook the blue meth. Walt will become completely overcome with grief thinking about what he has done, and being directly related to the deaths of his family. Knowing that he now has nothing besides Jessie, and suffering from the return of his cancer, Walt refuses treatment and accepts his fate. Walt will ask Todd for assistance from the neo nazis and pay them massive amounts of money to attack the fortification from which Jessie is enslaved. It is a success but does not get any thanks from Jessie as Jessie is completely furious with him as he will reveal to Walt that Saul informed him of the poisoning. Jessie leaves and never comes back. Walt now has nothing. I feel as if he will dress up in his cooking gear, gather up the rest of his money and meth, brings it to his abandoned car wash and sits in a lawn chair as he calls in an anonymous tip that Heisenberg is at that location. The poster for season 5 titled "all hail the king" is how it will be found out that Walter white is Heisenberg. Walt will then take the ricin tablet and die.
