what cartel tho...Gus killed them all
Walt Jr ODs on the blue crystals
Todd and his uncle takes over the business now that Todd knows the cooking process...eliminates Walt's entire family including Hank & Marie
Walt goes gun-blazing and survives, cancer comes back but doesn't kill him and leads a miserable life on the run...with Wendy the meth whore.
I'd be pissed if Jesse didn't learn about Mike's death
