How many times have these characters been played by the same actor? Does this explain GWM's chokeability, because in his heart he didn't want to defeat his former student and saviour Guo Jing? And in the archer duel after Guo Jing had returned to the wall (with Yang Guo's help), does this mean Guo Jing has surpassed the Jebe Wheel Monk in archery skills?
