Question about the story (Spoilers!)
In the last act, before the pastor's son and his followers go on a literal witchhunt with guns, the pastor and his son talk in the hallway of the church. The pastor reveals (I think) that he killed the guy at the lake years ago which they subsequently blamed on Aiden's mother, the witch, and burned her in the shack.
It was difficult to discern the dialogue, but why did the pastor kill that guy (I think his name was Jimmy)?
