New 'Homeland' Season 3 teaser: Who do you trust? (VIDEO)

                    

More teasers for the upcoming third season of Showtime's 'Homeland' means more questions. This quick one asks the pressing question we'll likely be asking all season. Brody's involvement in the CIA explosion is compromised, and you see Carrie expectedly defending him. I'm personally more concerned about Saul, but we'll have more to discuss when 'Homeland' returns on September 29th.
