Early life Nicki is the eighth daughter of Roman Grant, patriarch of the compound of polygamous
Mormon fundamentalists where Bill Henrickson was also raised,
Season One A season one plot line, reprised at the end of season two, showed Nicki to be a
compulsive shopper who incurred nearly $60,000 in credit card debt, unbeknownst to her husband or sister wives. 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. Although she has a strained relationship with her family at the Juniper Creek Compound, she is fiercely loyal to them. She has been shown going to some lengths to be a part of their lives and keep them a part of hers, much to the dismay of Bill and Barb. Nicki is shown to be such a favorite of her father's that it upsets her husband Bill. In one example, during the 5th birthday party of her and Bill's elder son Wayne, Bill walks in on her and Roman holding hands and laughing together on her bed.
Season Two It is revealed that Nicki has been taking birth control pills secretly for years. She is ostracized from the Grant family before her father is shot, and she steals from them to get revenge. Bill gives Nicki a power tool as an anniversary gift. 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. Bill, Barb, and Margie are furious; Bill tells her this is the worst thing she could have ever done to him. More than that happens, though; she catches her boss's eye and also attracts the Assistant District Attorney, who's set to go up against her father. More shatteringly, the evidence reveals to her that she was in "The Joy Book". She rips her pictures out of "The Joy Book" so the attorneys will not realize who she is. When she quits the job, her former boss, Ray Henry, kisses her goodbye. 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. Nicki and J.J. had a daughter named Cara Lynn, but when Roman finally allows her to become "unsealed," Nicki left her infant daughter behind with J.J. 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. Elsewhere, the finale shows Alby and Nicki plotting jokingly to kill Roman.
Season Four Nicki discovers that her father died and takes time to grieve. She decides to visit a fertility specialist, the son of her ex-husband J.J, who is now sealed to her mother. The specialist breaks the news that she is infertile, but he assures her they will attempt to work through it so that she may conceive. She drastically alters her appearance breaking away from her compound fashion by wearing normal clothes. In the season finale, she cuts her hair, which was always in a compound style braid.
Season Five Due to J.J.'s demise, Cara Lynn goes to live with Nicki and the Henricksons. Barb initially resists seeing that she'd have to divorce Bill, but eventually gives in with hopes that Nicki, Barb, Marge, and Bill can have a resealing ceremony. However, Verlan pleads with Alby not to kill his own sister. Nicki reminds Alby he saved her when they were younger. When Nicki returns home, she discovers Cara Lynn has an inappropriate relationship with her math teacher and tries to send her to boarding school. Cara Lynn ends up staying, but Nicki tells her that the math teacher was relieved to end the relationship and he "got what he wanted from her." Nicki breaks down after Cara Lynn has a meltdown in the backyard while burning her textbooks, but Bill busts into Nicki's locked bedroom door to comfort her. ==References==
