After four episodes, I'm ready to declare Homeland to be the best new show of the season--nothing even comes close. Carrie's scene with Brody at the end of the episode is quite fascinating. She spends the episode lamenting the loss of her surveillance after following Brody for weeks, and now she actively finds him out to insert herself into his life. Following with her history of sexual behavior with David and her advances on Saul, it's hard not to think something will happen between her and Brody. It brings into question her state of mind, whether she can control the crazy when with him.
Since her warrant on Brody expired, Carrie moves on and actually tails the professor for a while. When we think she's going to stumble on something big, however, there's an awesome twist in which the professor's wife gets a call telling her to ward the professor away from the house. She quickly puts an American flag outside the window and the prof drives past and to his listed address.
In the Brody household, the turmoil comes to the top when Brody shoots a deer with people at their home. After acting weird the entire episode, Brody really goes over the top and we have to wonder exactly how clearly he's thinking. If he has been turned, is it a conscience decision?
