As season 9 comes to an end, it is a good time to look at where the core themes and storylines brought us. While viewers might have anticipated a bloody conclusion to the season, the finale ends with a cold war situation - literally.

This cold war feel might make you long even more for a violent confrontation at this point. If so, why?
Having a close affinity with the dead, in this show, has an important metaphorical meaning. It is a way of showing the dark side of a group or character.

Hence, for them, switching between the dead and the living is a way of showing how their inner struggles are progressing.
