I saw scenes about overseas deals and the failure of Skyler to be able to add the amounts of money that was presented on the bands, but I only saw a montage of prison shankings/ one burning. There's no contract, but there was a sort of deal made, and yes, I agree that they won't just let him go back to his normal life. Walt was for sure buying that LMG in the first episode of this season in order to deal with these new partners, or the Aryan Nation. This leads me to believe that Hank isn't that much of a problem in the later episode...hopefully he is dead by this point. Any one person trying to take on the DEA by themselves with one LMG is a fool.
Other than the book in the bathroom bullshit, my biggest gripe with the writing took place with Mikes decision to have that dumb fuck lawyer deliver the money the way he did. Mike is a vet in the underworld. He knows how things work. A guy like that who knows that he has a DEA tail would not make the stupid decisions that he did. He would know for a fact that the DEA would eventually discover who his lawyer was, and would therefore be watching him. So he wouldn't have a guy that he knows would be watched by the DEA deliver the money to these fucks in safe deposit boxes. There is also no real reason that he wouldn't have had it delivered to the families of the guys in prison in one lump sum. The families are already accepting large sums of money from some guy, this means we can assume they know where it's coming from, and that they shouldn't make any stupid/large purchases that they couldn't explain to the IRS. In reality Mike likely would have found a much smarter/safer way to get the families their money in one fell swoop, they wouldn't be stupid with it, and things would have likely worked out fine in that arena. Just a short cut/cop-out in the writing if you ask me. Hopefully not a sign of things to come.
