The thing I kept thinking this whole episode is a thing that I tell myself sometimes when I'm freaking out, which is that anxiety is just time-travel. Rule #2 for a happy life: Your body has gone to a place in the future where you're going to have to fight, and sometimes you have to be really strong and dedicated to bringing yourself back to the present. To remind your body that you're safe, and the future isn't here yet.
Except for Carrie, that's not true -- her danger is clear and present, and her possibility for redemption has never been this close -- and for sure Dana's not wrong about any of this. It's just that she can't do anything about the problems, because she can't know anything about the problems. So it just sits in her guts like a monster, and she's permanently time-traveled, because nothing is changing and nothing's moving. Permanent readiness, carrying her whole family on her back. If you don't have sympathy for that, you've either never been a teenage girl in a bad family situation, or you've never met a human being before.
It's annoying as hell to watch, and given the chillness of the people on this show about people who are chill for a living, it seems unrealistic, but the fact is that Dana's freakout is exactly the right response: Not only too realistic to watch without cringing, but also ethically correct. Even if the targets she's choosing -- with the exception of Brody himself -- are really unfair.
Dana: "So why the fuck are we even here?"
Brody: "I told you!"
Dana: "Secret Reasons are not actual reasons! Nothing you told us makes sense! I am losing my shit everywhere!"
Jessica: "Damn, girl. I can't say I'm not impressed."
Brody: "Honey, this is just you freaking out. Let's chill."
Dana: "WHY DON'T YOU GO LIVE WITH THAT CRAZY WOMAN AND LET THE REST OF US GET BACK TO OUR FANTASTIC LIFE WITH MIKE FABER?"
Jessica: "She asked you a question, bro."
Quinn: "So whatever, don't worry about it. The world is still a much safer place than it was yesterday, even if we didn't get the main guy."
Carrie: "No, because until we get him, I still caused 9/11."
Estes: "So that was a fucking mess, huh? You got kidnapped, held hostage, wasted the whole day..."
Carrie: "Oh my God, I have to go wash my face with hand soap now. I've been awake for a million years and I am swiftly losing it."
