Nicolette Eugenia "Nicki" Grant[1] is a character in Big Love, an HBO television series set among contemporary polygamists in Utah.

[6] She often apologizes by saying, “Well, that’s just the way it is.” Like her mother, she has a nonchalant attitude toward things like guns and fraud (i.e. fake birth certificates).

Do you think she just carries the equipment around with her all the time?”[7] Nicki retains a strong belief in "the principle" of polygamy, as well as modesty in dress[1][8] and a deep suspicion of the world outside the compound.

After accumulating $60,000 in credit card debt, she passes the buck by focusing on the faults of Bill and Barb.

[8][9] Although Nicki is frequently portrayed as cold and unsympathetic, there are many instances where she is shown to be quite passionate about her beliefs and towards her loved ones.

[18] Though it goes against their rules of morality, Nicki starts gambling at a gaming establishment to which Bill introduced her in an effort to share his new business venture with his wives.

[20] Barb and Margie escort her to the fertility clinic thinking it's a medical issue; it's been 4 years since her younger son's birth and it's technically her turn to have another baby for the family.

[21] When Nicki's father, Roman, is in jail awaiting his trial, she is temping at the District Attorney's office (as "Margene Heffman").

[25] It is revealed that Nicki was married to an older man named J.J. Walker (Wanda's brother) when she was fifteen and still living at Juniper Creek.

[31] She pleads with Barb and Margie to save her from the unsealing ceremony, but both sister-wives are on Bill's side and refuse to help her.

[31] She goes undercover to prevent Bill's political opponent from winning the Republican state senate nomination.

[33] This sends Nicki into an identity crisis, wondering if her sole role in life is providing Bill with children and further expanding the Henrickson family.

[6][35] Also in the finale, she goes against her characteristically cold demeanour when she informs her sister-wives that she wants Bill all to herself and will stand by him even if they do not.

[37] When Nicki returns home, she discovers Cara Lynn has an inappropriate relationship with her math teacher and tries to send her to boarding school.
