At the end of the first episode of the third season (s03e01 : Tin Man Is Down) Carrie watches Saul's testimony on live television and is distraught. She is at home, alone, on her bed when she watches the television and she seems to be very distressed. Saul here announces the relation between Brody and an bipolar agent (not to mention Carrie before the committee).
Later on the fourth episode (s03e04 : Game on) we learn that the forced internment that Carrie has been through is a part on a well planned, elaborate and secret operation between Carrie and Saul to approach the Islamic terrorists.
So if all the beginning of the third season (the first four episodes) was planned by Carrie and Saul why is Carrie distraught while watching Saul's hearing before the Intelligence Committee ? I understand why she acts unstable, panicked or whatever while other people are around but in her bedroom alone ?
