Actually, I’m sure that a lot of people agree with you. I don’t.
Mostly, I don’t agree with the idea that Carrie has never before suffered the consequences of her actions. Yes, the psychological warfare that she suffered in the Russian prison was something quite definitely else, but she was locked in a mental institution for weeks in season three. She watched Brody die after spending an entire season attempting to prove him not only innocent, but heroic. (And Brody, for the record, was completely at peace with his own death.)
We don’t know what, exactly, happened to Carrie in the seven months she was held captive in Russia. Psychological torture, certainly — at the very least she was left to her mania. You can’t take physical torture off the table. We don’t know what drugs she was given.
But this is what Carrie signed up for. She knew what she was getting into. When Yevgeny refused her meds, she knew what was going to happen.
I know this experience will change Carrie, but I don’t agree that it will change her devotion to her mission or to her country. Brody was turned, sure, but it was Issa’s death that really changed him, that made specific Americans the enemy. He still loved his country. And he still made sacrifices. He put everything on the line — except Carrie, really, and even that was like… it’s not like he didn’t want Walden dead, you know?
But at the end of the day, he still sprinted into Iran under the cover of darkness, watched his fellow soldier die at the hands of Majid Javadi, and completed his mission to kill Akbari. Never with any guarantee that he was going to get out.
We’re coming up on the last season. The last mission. It would be really fucking unbelievable if Carrie let anything get in the way of it.
