So, before sergeant Brody was to blow up the room filled with American politicians in Homeland, he made a video in which he "explains himself". In season 2 Carrie retrieves a bag with some documents she grabbed from the apartment of a man (Abbas Ali) after he was shot by Americans during his meeting with Abu Nazir in Beirut. At the end of episode 2 Saul finds the mentioned video of sergeant Brody sewn into the side of the bag...
I missed the process of this memory card ending up in the bag of the guy that was mentioned for the first time in the series. But it is possible that this Abbas Ali appeared before, and I just forgot. Can anyone fill me up on this?
