I kinda have atheory about maybe knowing who is this Yellow King in True Detective, well i have a litle doubt.
SPOILER:
In episode 5, when Hart and Rust go to the farm where the 2 guys , Hart seem to have a natural instinct of looking behind that door where he find the children. We then see again his impulsive temper as he blow up the head of the guy. Was he pissed because of the condition the childrens were or because it was simply because it was childrens laying back there? You see, Hart got Yellow hair, an impulsive temper... Oh well...its just something that i tough, that Hart might be the one....
