From a commentary by Jeremy Egner on "Game of Thrones," Season 6, Episode 5. New York Times, May 23, 2016.
"I'm curious and also slightly afraid to see how much an already convoluted show will further complicate itself with this new element.
"But in this case, the Möbius strip approach worked, imbuing an already suspenseful and sad moment with deep poignancy and meaning."
