I'll revive my earlier bit - this is why BB is so goddamn amazing. Why it puts Sopranos and anything else in the history of the medium to shame. It's also something you know damn well VG learned his lesson from the king of all screw-ups in this realm, X-Files.
Planning. Unlike so many other shows, they clearly planned this. That "confession" video? Just amazing. Ties everything together. Then boom, Hank's done for, so they pull the one other dangling plot thread to destroy Walt, the one man who *he* destroyed, like so many that destroyed him that led to him becoming Heisenberg. I doubt they'll ever reveal the whole "Walt could have saved OD chick," but as I remember it Jesse not only had the guilt of losing/killing her, he then felt even worse with the plane crash due to her ATC father... Walt has a debt to settle with Jesse, and it looks like we get to see that. This entire show has been about building Walt up from nothing, at the same time stripping it all away from Jesse. Walt's greatest triumph, the Methylmene robbery, was the final blow for Jesse. It's all been one dramatic two-sided story, now those sides come to a head.
They could have gone for the cheap entertainment, Hank Versus Walt. Instead they put that aside, putting it aside in a masterpiece of years of plotting all combining for an epic payoff, to get to the true meat and taters of BB.
