Christopher had many days to think about the current situation, and confirmed that Marcus was not working with Jeff.
Christopher wonders: how is it possible that Jeff defended from all the attacks flawlessly?
He knows that Jeff has ways to get the information which others find impossible to obtain. Considering how close Jeff and Aiden are, it is reasonable to believe that Aiden helped his brother. But even if Jeff knew every step Marcus planned and had Aiden's support, it would take a lot of resources to repel all those attacks like they never happened. Marcus assured Christopher that forces under Jeff's command will not be enough to prevent most of the attacks, so... what happened? Of course, Christopher does not know about everything that Marcus planned, but the fact that not a single incident leaked is a sign how formidable Jeff is.
