First of all - spoiler alert on the Gretchen thing? C'mon. Not like that is a crazy reveal that ruins the ending, but I know I personally don't want to see stuff like that.
Second, the Jesse cooking thing doesn't work for me. Instead of getting you arrested, or harming your family, while in custody of a DEA officer, I'm going to start cooking meth again? Correct me if I'm wrong, but Jesse has no money, meth, or supplies does he? I mean, maybe he has some money stashed, but I'd imagine Hank or Saul has that fat stack of cash he was hitting the road with? Walt is out of the game. Retired. He's worried about the safety of his family. Not his reputation as Heisenberg.
We know the money has to come into play at some point.
Not sure I understand the fake hit. If there is no dead body, I don't think Hank is going to by for a second that Walt is dead. I trust Gilligan so much that I don't try to predict what is going to happen. I know that he is going to surprise me.
