As expected, the midway point of True Detective, which happened to be the big shootout in True Detective Season 2 Episode 4, shook up the format of things going forward.
In True Detective Season 2 Episode 5 we learned the case was closed, and everyone had moved on. But as Katherine Davis pointed out in the middle when she rallied the three detectives back together again, it was closed while thrusting a shady Attorney General into the race for governor, and the whole thing just didn't sit well.
It seems what makes a true detective this season is someone who doesn't give up. Someone who will care, even when nobody else will.
