Continuity mistake: When Walt breaks the news that Gray Matter is broke, Skyler's hands are on her stomach, we then see her hands are by her mouth. (00:38:50)
Continuity mistake: At the very beginning of the episode, Skinny gives Jesse the address on where he can find the junkies who robbed them. When we see the piece of paper, the street name is Pampas. When Jesse gets out of the car, we see the real street signs, and that the house is on 13th and Marquette.
Continuity mistake: When Walt and his wife are on the couch talking about Gretchen saying she was not going to pay for the treatment any more, Walt puts his hand to his mouth when she says that she called Gretchen back but she wouldn't pick up. His hand is over his mouth with his fingers pressed up against his nose. When it cuts to a different angle, suddenly it is just one finger against his lips.
Chosen answer: I'm not sure how far you are into the show but he does eventually come up with a way to launder it (wont spoil it for you but rest assured, when he gets a lawyer the show gets much better!) and in the final season he also comes up with a way to give his children his money without the cops or the DA knowing it came from him.
