Carrie had to know Quinn was going to shoot her — what was motivating her to press on in that moment?
The character of Carrie Mathison is an impulsive one. And sometimes that impulsiveness takes over. I think she’s sitting in that van, and all of a sudden understanding that this is the person who could exonerate Brody once and for all. The actual bomber, the face of the murderer … you parade that in front of the public, and all of a sudden the people start questioning if Brody had anything to do with it. When it looks like that is going to be taken away from her, I think her emotions come into play. She’s carrying Brody’s child, and it completely consumes her. She has to get out and stop it from happening — to the exclusion of all else. It’s that impulsive nature that takes over. If she had time to think about it, she’d probably say, “Wait a minute, that’s not a good idea.” But that’s not Carrie Mathison. (x)
