Leaving Rusty to deal with the deadly little doll all by his self?? Hopefully they have cigars and whiskey about to keep the little guy sated…

Oh yeah, Allen can be a master story teller: One moment Mark is apoplectic to see Dr. Carter’s voodoo fetish “guard doll” show up in an unmarked package sent to Rusty; the next moment he is peacefully leaning against the cabin wall, listening to Ol’ Doc’s nonsense.
So where is Rusty and his fetish? Perhaps the voodoo image forced Mark to leave the room and forget what happened, while it also takes over Rusty’s mind. Action ensues.
