Hombre (1967)

Plot hole: Towards the end of the film when Newman and the remaining stagecoach people are in the cabin at the top of the hill, Richard Boone's character sends one of his two henchman (the Anglo, not the Mexican) around to the back of the cabin to apparently surprise them from behind. Then Newman's character walks down the hill and Boone and the Mexican henchman are all killed in a shootout. Everyone comes out of the cabin, comes down the hill and the credits roll. I guess that now, almost 40 years later, that poor Anglo-henchman is still behind the cabin, waiting for them to come out.

John Russell: Hit something, Mendez, first the men, then the horses.
Henry Mendez: I don't know. Just to sit here and wait to kill them?
John Russell: If there was some other way, we'd do it.
Henry Mendez: Maybe we can keep going and try to outrun them.
John Russell: If you run, they're gonna catch you, they're gonna kill you. You believe that more than you believe anything.
Henry Mendez: All right.
John Russell: And try not to puke. You may have to lie in it for a long time.

Question: Who dragged Richard Boone into the cabin after Paul Newman shot him? Mrs. Favor? Was she in on it?
