The Season finale of "Homeland" Season 3 saw the shocking public hanging of Nicholas Brody. His death has opened up the possibility of a new arc in Season 4, but his presence will be seen for some time in the new season.
"The story finds Carrie in an emotional space that is very much a continuation of last year's story, and the spectre of Brody is still felt very strongly," Howard Gordon, executive producer of "Homeland," said to TV Guide.
The final episode also saw Carrie finally telling Brody that she is pregnant. Brody and Carrie's baby will make an appearance in "Homeland" Season 4. Carrie will be seen juggling her duties as a CIA agent and as a mother. And, Brody's present will be felt "very strongly" because of his and Carrie's kid.
