Mike joins Walt and Jesse, they destroy the video evidence on Gus's computer with a giant magnet near the evidence room, they start cooking meth in houses by investing in a pest extermination company, Skyler hates Walt and wants him to die of cancer already, she sends to the kids to Hank and Marie's after a fake suicide attempt in their pool, they rob a freight train and take 1000 gallons of methylamine, they murder a 14 year old boy, Mike and Jesse try to retire and sell the methylamine, Walt fucks them over so he can keep the methylamine and continue building his drug empire...and that is what happened so far this current season.
