Jr. tells Dad he hopes he dies and hangs up on him. He knows Walt is responsibile for Hank's death. Walt cries. He feels so bad that he calls the police to surrender. But before they arrive he's gone, with his pile of money.
What's keeping him going probably is a plan to off Jack and Todd. Perhaps he will try to get Jesse involved in that. He may use ricin, which is the reason he's headed back to his former house.
Meanwhile his cancer has advanced to the extent that his wedding ring falls off him. But what he is wedded to is the past. Skyler will likely be going to jail. She's already talked with the authorities.
The only real missing piece is what will happen to Jesse. Andrea has been shot dead. Jack wants him only to cook up another blue batch of meth. Will Jesse commit suicide? Will he turn himself into the police? Will he goad Jack enough to shoot him (unlikely)? Or will he join with Walt in offing Jack? Jesse frequently defaulted back into compliance.
There is one episode to go.
