Hannah is able to convey what she knows about Vice-President MacLeish to Tom, including that he was in on the Capitol bombing, which in turn was not orchestrated by Al Sicar. However, the legal advice that Hannah receives, the advice received on Tom's directive, from a trusted source is that they do not have enough evidence to convict MacLeish if they were to bring him in now, despite they all knowing that he is guilty. As such, Hannah, who still has to be seen as being in custody by the conspirators to hide that the authorities are getting closer to discovering the truth behind MacLeish, is tasked with finding the conclusive evidence, the strongest being something to come directly out of his mouth. Hannah believes the two strongest leads are the mysterious woman who is known to be involved in the kidnapping of a still missing Luke Atwood, and the rest of the team MacLeish led in the military. With the information that Tom now has in hand, he feels the need to return to the White House as quickly as possible to resume control, still without tipping his hat to MacLeish until that conclusive evidence is obtained. Tom also learns for the first time about the telephone call made from Aaron's telephone possibly implicating him as one of the conspirators. As Tom has been advised by Mike to tighten the circle of people that need to be in the know about any of this information, including excluding Alex for her own safety, he needs to keep Aaron out from the loop without he knowing he is being excluded, all in Tom's mission to find Aaron not guilty of what is implied by the on the surface evidence. This becomes more difficult as Aaron has to act as the liaison between Tom and Kimble, who seems to know more than he does in his role of Chief of Staff.
