Walt already did "break bad" I mean come on, what else do you want?
What do you always hear as a standard rule look to what Hector told that kid when he was drowning the other kid...?
Family!!! nothing means more then family and when Walt finally breaks all bad is when he kills a family member meaning Hank. Over the next few weeks of shows he is going to start thinking about it being Walt. Then the last show this year is most likely Walt doing something to Hank as a cliffhanger or about to.
