Homeland: Everything You Need to Remember Before Season 7 Premieres

Saul works to uncover the nuclear agreement conspiracy, eventually realizing his colleague Dar is behind everything. But it doesn't matter how much Saul helps to uncover the conspiracy in the intelligence community; he is still seen as a threat by Keane, so she has him arrested for the assassination attempt on her. Perhaps in season seven he and Dar are sharing a prison cell (kidding, kidding).
