Homeland Season 4 Spoilers: Trailer Shows New Information on Carrie, Saul, Brody and More

The newest Season 4 trailer of Homeland drops plenty of intel for viewers to absorb and clears up some mysteries about the upcoming fourth season.

Firstly, we see Carrie (Claire Danes) and Saul (Mandy Patinkin) working together. The two were on shaky ground throughout much of Season 3, and Saul left the CIA at in the finale. But Carrie reluctantly accepts his help in the trailer, which could mean the two become allies once again.

Secondly, we see Carrie with Nicholas Brody's (Damian Lewis) redheaded baby. Carrie was pregnant with the child last year, but he's been born when Season 4 begins, it seems. Carrie's sister Maggie (Amy Hargreaves) accuses her of getting her overseas job to avoid raising her daughter, which could be true knowing the damaged Carrie.

Corey Stoll also features heavily in the trailer as CIA station chief Sandy Bachman. He is billed as a guest star, but the trailer implies that he will stick around for most of the season as viewers question his true allegiance.

Elsewhere in the trailer, Saul watches a viral video called "American Missile Strike on Wedding," which shows footage of a CIA mission, presumably a drone strike, that goes wrong and becomes a headache for the agency.

Finally, Quinn (Rupert Friend) is back and we see him protecting Carrie from an angry mob of people in the trailer. Tracy Letts is also back as Senator Lockhart.
