great theory...i've always thought that guy was just 100% straight psycopath and WAY too interested in the cooking methods. He wants to be king.
10 days til the "season" premiere.
I think the flash forward in the diner that started season 5 has plenty of stuff to ponder...
Walter has hair so he is not receiving cancer treatment such as radiation yet he is taking pills and coughing again.... To me the cancer has returned and they can't do anything to stop it. He knows he is dying so has little to lose.
Walter not only has a New Hampshire drivers license he also know how long it takes exactly to drive from there as he tells the waitress. He HAS just driven from there in my opinion and has been living there under an assumed name.... Perhaps in witness protection?
Hank may have figured it all out but Walt might manipulate him into letting him become an informant on the "real" drug lords (his distributor from Arizona or Todd's uncle's guys perhaps). Hank is going to look like an idiot if he reveals to his bosses Walt is a crook especially since his dirty money helped pay for Hank's physical therapy.
I suspect Hank will let Walt leave town with his money or at least some of it (he pays for the big gun and tips the waitress $100 so he isn't broke - then again it might be the last of the money he has since he knows he will die).
I think Hank and his wife will be killed by whoever Walt frames for his crimes and that is the reason Walt returns to town to avenge Hank. Hank is the only honorable person in the entire show besides Walt jr so Walt owes him that.
