The reunion happens in episode four, but trust, it is: Worth. The. Wait. Now that Saul knows the truth about Brody, he and Carrie will work together again. This all leads to an insane encounter where Brody and Carrie try to "bury the hatchet." We're not going to spoil how it all unfolds, but believe Team WWK when we say you will not see the end coming. Season two of Homeland is moving even faster than the first!
