You were an engineer from the 21st century, and you had invented a theoretical time travel machine. In testing it, you accidentally transported yourself to the year 1899, near a cliff of some sort, overlooking a valley and river. You heard what sounded like hoof steps approaching. There was a man dressed in cowboy attire, sitting atop a horse, revolver in hand.

"Who're you? And why you... All dressed up like that?"

Arthur asked, suspicious of this odd-looking stranger that was near his gang's camp.
