A neat idea for a BB "Encore/reunion" episode.
In the universe of BB, the exploits of Walter White would have been a huge, international story.
With the popularity of streaming, multi-episode docu-series, it is conceivable that Netflix or the like would commission a detailed series on Walter white and his short-lived meth empire.
How cool would it be if they were to make a mockumentary series set in-univerrse that catches up with characters from BB in a retrospective? we could get the perspective of the events from minor, but central characters and a follow-up of how they have been effected by the fallout from them in the years leading up to the present. Characters like Ted Benekie telling his side of the story, Jessie's parents trying to explain where he went wrong, Skyler explaining her current circumstances, Walt Jr., Marie, etc. Jailhouse interviews from characters who went down hard. There could be an addict or two explaining how their lives were effected by the flood of blue meth. Many different places you could go with it.
It'd be really cool to see how the Heisenberg incident effected the world of BB from a more macro and meso perspective and provide a meta-analysis of the events that the audience got to see first hand.
I think its an iterating idea that hasn't really been done before.
