I'm trying to figure out the logistics of the theory of Walt getting the money back from the Nazis to give to his family. Now that Walt has "confessed" to the police, doesn't that allow for them to put the family under surveillance for a long time "for their own protection"? Heck, they could put Skylar and the kids, perhaps even Marie, into witness protection. I'm guessing "Hey, we won the lottery," wouldn't keep the police from investigating where $80m came from.
I rewatched the phone conversation today. I can pinpoint the moment Skylar got that it was an act from Walt, but could use her still being upset about Holly and Hank to her advantage.
