I don't know how things are going to proceed now, but I will say that if Jesse is ever disrespectful, flippant, or condescending to Walt again he deserves to have his neck snapped. The things Walt has done for him over 3 seasons now borders on ridiculous, especially with the stakes this high. I'm sick of that jackoff and his attitude toward Walt, it's his own fault he kept getting his ass kicked, he never knows when to shut up or back away.
Let's see what Walt has done for him so far.. Avenged Tuco for kicking his ass, saved his life in the desert, got him out of the crackhouse and into rehab, fired his lab parter who he had a great bond with, protected him from Gus, and now ran over and killed 2 men out in the open leaving him vunerable to all sorts of trouble with the law (that's just off the top of my head, I'm sure I missed a few more)... even if Jesse were his actual son I wouldn't believe the things he did for him.
