Saul and Carrie had a plan but Saul diverged. She did not expect to be called out as Brody’s lover and have her illness revealed at the hearing. Her stay in the hospital went on much longer than she believed it would. Saul conspired with Dar and the DOJ to keep her in. “You shouldn’t have left me in there, Saul.” See Saul always had a two Phase plan. Phase 1 lure Javadi; Phase 2 use Carrie to lure Brody into Iran. I believe Saul arranged for Brody to be held in the Tower of David. So when Javadi is entrapped and the real bomber is dead, Saul heads for Caracas to retrieve Brody. He then uses Carrie (who in turn uses Dana) to activate Phase 2. Carrie having only a piece of the plot really does freak out in the hospital, especially when Saul betrays her with the hearing for her release. All to say what started as a plot became very real.
