No, but they do require a viewer to think (an ever increasing rarity in tv dramas these days).
And you are supposed to be left wondering what is going on/has gone on. The storyline from these 2 eps isn't over yet. When taken as a whole (which my guess means the story will play out bit by bit in some episodes, and climax in the finale, which is why its a 1 part finale this year, not a 2 parter) the storyline will make sense. Just not yet.
