After all that grief and pain of not caring about the William arc, it ends very lack luster with the episode bearing his name. A man shows up in the XF office and kicks the crap out of Doggett's head. In spite of this, Doggett is still able to apprehend him. We find out he is badly deformed and his true identity is up in the air. There is a lot of speculation that he might be Mulder, but Scully is reluctant to believe it. It turns out to be Jeffrey Spender and his whole purpose was to make William unspecial by injecting him with iron to kill the alien DNA in him or something or other and Scully gets mad at him. I really don't find this episode very interesting.
