Spoiler for Part 6
Moderator Pieter Dom surprised us at an early stage with the Lynch/Frost titles for the first 8 episodes. Episode 6 is called 'Don't Die'. http://welcometotwinpeaks.com/news/twin-peaks-parts-1-8-descriptions/
Who will be dying?
Actor Miguel Ferrer died January 19th 2017, during takes I presume.
Filming was completed in early 2016.
Also, my father, like Ferrer, died of throat cancer. I'm not sure when Ferrer was diagnosed, but he seems to be in good shape here; he's not showing any of what I perceive usual symptoms (drastic loss of weight, speech difficulties, numbness).
As for who might be dying, I have no clue. I dare not have a clue.
