 Because the script of the episode does not specify the identity of an unseen person who slides a file about Gibson Praise under Doggett 's door , Kim Manners later had to ask the writers who the mysterious visitor was ; the director was told by Chris Carter and Frank Spotnitz that the unseen person was actually Kersh . Robert Patrick asked the same question of Manners , around this time , but the director – not yet sure of the answer and hoping to avoid looking foolish – never gave the actor an answer . Patrick thought the reason that Manners was being purposefully secretive was that the director wanted Patrick to still be in wonderment as to the mysterious visitor 's identity , as a device for the actor to aid his performance . Manners later teased Patrick that the reason he had not answered the question was that he had not liked Patrick at the time , prompting the actor to ask what he had done to annoy Manners on the first night of filming the episode . Eventually , the director finally admitted to Patrick what had actually happened . Kersh 's actions are later revealed and explained in the ninth season premiere " Nothing Important Happened Today " .
