OK, so I know Glen Mazzara confirmed the episode 9-16 titles on his Twitter, and that he said episode 14's title was changed. But on the schedule on AMC's website, they still list episodes 13 and 14 as "Pale Horse" and "Killer Within: Part II", respectively. The finale is not named.
So, what is what? It just seems like AMC would update the titles if they were changed.
