Breaking Bad completism. Indeed the canon was already complete, as I also learnt from Better Call Saul. These are inessential offcuts from the TV show threaded through Jesse Pinkman's present-time escape to Alaska after the big finale. There is some minor unfinished business but mostly it's about getting enough money together to pay the extractor. Somehow we know he survives so there's no tension in any of the scenarios.
James Poniewozik: extends but does not add.
