Speaking to TV Guide, Robert King explained that Alicia (Julianna Margulies) will have to decide whether to support her husband Peter (Chris Noth) in his political campaign.
"With Peter's exoneration, the question will turn toward whether politics makes him that way or whether there's something in him himself," King said. "With him possibly wanting to run again, Alicia faces the idea of, 'Even if I do forgive my husband, does that mean he will always make these same mistakes?'"
King added that Will (Josh Charles) may choose to be with law student Giada (Karen Olivo) but Alicia will have to consider her relationship with him.
"Even though he's her boss, does he cut too many ethical corners?" King said. "Is he some version of her husband? It makes her wonder about her own character. Is she always drawn toward the bad boys?"
King also revealed that Alicia may decide to be single, saying: "So much of the show announces itself as this love triangle, when in fact, maybe the best thing for Alicia altogether is to say, 'Screw this'.
"Part of her rebuilding her personality and her self-worth is this idea that she doesn't need somebody else. That is one of the questions of this season and next season."
The season finale of The Good Wife airs in the US tonight at 10/9c on CBS. The show continues in the UK on Thursday at 9pm on More4.
