MORE BREAKING BAD SPOILERS...
What an outrageously delicious moment it is when Walt declares, "I won."
Of course, as Jeff points out, the tragic irony is that Walt is almost completely lost.
The real reason for my post, however, is that I just thought of and want to believe that Gilligan and his writers knew exactly what they were doing when they introduced Hector Salamanca and his bell way back in Season 2. I'm okay with it being a happy accident, too, but I don't think so. I think that that bell always had a nefariously efficient narrative purpose.
