Would Hillary throw her aide under the bus if she thought the FBI was going to exonerate her?

Hillary Rodham Clinton and her family personally paid a State Department staffer to maintain the private e-mail server she used while heading the agency, according to an official from Clinton’s presidential campaign.
Editor's notes:  The Wa/Post article does not make this connection,  but I believe Hillary is setting the stage to blame her aide,  a man named Pagliano,  for the presence of classified information on her server and the alternation of documents,  deleting the markers making a document "classified."  
If if if,  I am right,  Hillary believes the end is in sight,  and, believes FBI  investigation is about to "go criminal."  
Understand this, you may know that Pagliano is taking the Fifth before the House committee,  but, you might not know that he, also, plans on not cooperating with the State Department should it go to him for information.  More than this,  apparently he is making it clear that he will plead the Fifth should the FBI call him in to answer question    . . . .   nothing guilty going on here,  right?  
assume my theory is correct,  don't you know that Pagliano knows he is being thrown into the fire; that best explains why he is refusing to answer question.  More than this,  IF my theory holds true,  he will be offered full immunity for his testimony.  
If this scandal ever gets to that point,  it will not matter if Hillary is found guilty.  She will be done,  if not replaced, by the DNC.
