Also, I think the look on Walt's face at the money room really showed why he decided enough was enough. I know he said earlier that he was in the empire building business, but ultimately, confronted with that overwhelming mound of cash that Skylar couldn't even count, and when she asked him how big this pile needed to be, it put into perspective the futility of his whole goal and what he was doing it all for, because he already had more than he could ever want or need for anything in the world. [g]I could be totally wrong, but in my mind the organic way in which he looked at Skylar almost shyly, smiled briefly and walked away seemed more sincere.[/b] I could see him lying to Skylar and staring her down and saying "read my lips. I am out. I'm done. It's all over, okay?" and staring her down until she responded, but he seemed more relaxed in that scene. It's also possible he got his diagnosis in a scene we did not see that the cancer has returned, and he's re-prioritized his life yet again.
