The producers of “Homeland” are really building suspense for the third season by posing more questions than answers in the various teaser trailers they’ve released thus far. The first featured mostly just audio, the second reminded us of where we left off (Brody on the lam! Tons of people dead! Saul is sad!), and now the third is a surreal dream-like sequence featuring our three main characters (Brody, Carrie and Saul) confronting/becoming one another. Also, Brody has a shaved head, which looks pretty hot.
