Saylor's character Dana has been scrutinized since the series' launch, but became a focal point of fan contention this season when given a more prominent role. With Brody (Damien Lewis) absent for most of the beginning of Season 3, the focus shifted to Brody's family, specifically Dana's struggles in the wake of her father's alleged terrorist attack.
Baccarin's appearances this season were already less frequent than before, likely due to the actress' pregnancy during filming.
Homeland's Season 3 finale airs Sunday at 9/8c on Showtime.
