Homeland season 7 spoilers, cast update: Premiere to begin with 'Quinn's death and Carrie's grief'

Homeland season 7 will begin by featuring former CIA officer Carrie Mathison's thoughts about the dearly departed hitman Peter Quinn.

Co-creator and executive producer Alex Gansa revealed that Carrie's thoughts about Quinn will "push her" to work against the "systematically abusing power" of Keane administration.

"Quinn's death and Carrie's grief for him are everywhere – colouring her every thought," the showrunner said in an interview with TV Line.

Adding on, Gansa said that the loss of the death-defying hitman will "push her to reassess what's really important in her life" and "contempt for President Keane".

The co-creator then said that Homeland fans can expect to watch Carrie's "righteous indignation" and Keane administration's "systematically abusing power, ignoring the rule of law, and permanently damaging our democratic institutions".

With regard to the newly-elected president Elizabeth Keane, Gansa said, "For us, Keane is neither a villain nor villainous. She's an embattled and isolated president, trying to hold on to the reins of power in a deeply divided country and dangerous world."

Meanwhile, the seventh season of Homeland has added Russian-born Australian actor Costa Ronin in the cast list. However, the details about his role are kept underwraps, reported Variety.

Check out the official synopsis below:

At the end of last season, following an assassination attempt on her life, President Keane broke her promise to Carrie by arresting 200 members of the intelligence community without bringing charges against them, including Saul Berenson. As season seven begins, Carrie has left her job in the White House and moved back to D.C. and is living with her sister Maggie to take on the Keane administration and secure the release of the 200.
