Pointcrow and Doug, there is only one way to settle this... You must fight each other in pokemon with Xerneas and Yveltal to represent the X axis vs the Y axis.
as you said yourself, the cliff ledges where you are granted respite are intersections of two lines. you cannot surmount the challenges that face you with only one line. both the hurch and vurch, equal and opposite, require the other to prosper.
Though Doug’s path was easier that simply shows he did not truly go on the great journey. he was not ordained by the forerunners of the line. He followed a false path. All heretics must be slain. He is nothing but a voice that must be silenced.
