So what happens to Saul after this season? I mean it doesn't seem like there is anyway for him to keep his job as Director of CIA, he had the opportunity with those photos of Lockhart and chose not to use them. Also, it doesn't look as though he can stay at the CIA has he and Lockhart simply to disparate from each other to effectively work together.
Thus, there are only three options.
1. Saul gets promoted to something like the Director of National Intelligence. This seems unlikely as the position removes him further away from directing and conducting operations personally and is more of an administrative role.
2. The White House decides to create some new unit totally dependent from the CIA which Saul runs, something similar to CTU in 24. There are a couple potential problems of course. One, is that this runs the risk of being too similar to 24. Second, it has the potential of removing the show further from reality, though at this point that doesnt seem much of a concern. Lastly, is determining just exactly what kind of jurisdiction this new unit would have, is it allowed to operate on domestic soil or foreign only?
3. Saul quits he finishes his tenure as Acting Director of the CIA and retires to a nice quiet life with his wife. This is the least likely course as his character is one of the few things that keeps the show alive. Though, they could always invent some crisis to bring him back into the game just as they seem to do every season with Carrie.
