So what is Brody's real agenda, if he even has one? There are plenty of indications early on that Mathison's suspicions about him are correct. But are his visions memories, or simply hallucinations? Does even the fact that Brody kneels on a prayer rug in his garage, chanting in Arabic, mean he's a bad guy, or merely a zealous convert to Islam? This show is too smart to give away too much too soon; red herrings abound, and the season ends with a cliffhanger sure to leave Homeland adherents salivating for more. In the meantime, those looking for a marginally more credible and only slightly less entertaining alternative to 24 are in for a treat. --Sam Graham
