Can someone refresh my mind on what happened in S2? I really can't recall.
Brody, now a congress-man, does trainee-level tasks for the terrorists while also trying to become running mate of the current Vice President. Carrie ends up working for the CIA again pretty much just because and manages to find Brody's confession memory card, which leads to his arrest and a bunch of double agent shenanigans. Eventually Abu Nazir enters the US and sort of stays there until he is caught and killed, a bomb goes off at Langley killing Estes and Carrie promises to love Brody forever and clear his name because someone leaked the confession video. Mandy Patinkin sighs and silently wonders where it all went wrong.
Also a bunch of Dana bullshit.
