How much does what we know about something actually matter? That’s the question that I found myself asking while recapping “Still Positive” over at Slant Magazine, as so many of the seismic shifts on Homeland are predicated on awful information. Saul and Carrie’s entire operation, apparently thought up the very next morning after the bombs blew up Langley, operates from Saul’s thirty-year-old memories of Javadi, and though it’s successful, it comes at the cost of several innocent lives this week, largely because Saul’s been distracted by other forces that he thought would never change: his position at Langley, which Senator Lockhart’s about to take over, and his relationship with his wife, Mira, who is now happiest only with another man. And while Carrie’s big gambit, the play she makes to get out from Javadi’s rather cheerful interrogation (and to place him in a certainly icier one) works, it’s not because the CIA was there to protect her, but because she believed they had her back. Nobody knows anything for sure: both Saul and Lockhart believe Dar Adal is working for them, and Carrie’s practically building a fort of used (and positive) pregnancy tests, as if she can’t trust the evidence that is right before her eyes. That’s what Homeland is most about this season, recovering from a loss of a trust, and whether you buy into that or not, it’s hard not to give Homeland itself the benefit of the doubt, trusting that the show-runners know exactly where they’re going–even if we don’t.
