Jesse says he has to hit Walt where it hurts to most... I am guessing that's his ego. I am guessing Jesse starts cooking the blue again with hopes of drawing Walt out of retirement. Walt has never wanted others to cook his product or make money off it. The only problem with this is Walt is too smart and will see it coming. Anyway, who knows at this point...
I now hate Hank and would be fine if he dies. I was shocked at how little he cared about Jesse and with him going off the books and doing this all for his own selfish purposes makes him almost as bad as Walt IMO. The only innocent people on this show are the two kids it seems. Everyone else is breaking bad..
