A fiery redhead who has a bullying, confrontational, sarcastic personality, Reba tries to take control of every situation, which more often than not makes problems worse before they get better.
In the first season, she is struggling to save her twenty-year marriage to Brock before she learns in a therapy session he is divorcing her to marry his pregnant girlfriend, Barbra Jean.
In the second season, Reba continues to move on from her divorce, even getting a boyfriend for a brief period, selling off her engagement ring, and accepting a job from Brock in his dental office.
Fearing he will have another mid-life crisis, Reba develops empathy for Barbra Jean and opens up to Brock about her feelings after the divorce.
After losing her own job in the dental office for calling her boss "a monkey's butt," she pursues a career in real estate and hires Van as her assistant.
Meanwhile, Reba also suffers health problems, in one episode she gets laser eye surgery because of her poor vision, and she collapses at Van and Cheyenne's second wedding because of high blood pressure.
After Kyra considers several colleges, she decides to put her education on hold to go on tour with her band, a decision that enrages Reba initially but she later supports.
In the second season Brock is living a quiet family life with Barbra Jean and Henry and gives Reba a job at his dental office.
In the third season Brock shows disapproval at Barbra Jean's mother hen nature over Kyra, but drops a bombshell when he reveals that he intends to sell his dental practice to become a professional golfer.
Brock moves back into the house and allows Reba to sell his condo, and Barbra Jean buys a dog she names Broque.
In the fifth season, while Cheyenne is battling problems with an alcohol addiction, Brock secretly begins smoking again after he lectures Kyra and Jake not to do it.
The two decide to file for divorce after Brock continues to lie and deceive her-in one instance getting his vasectomy reversed so he can get Barbra Jean pregnant again.
Cheyenne, who had been co-captain of the high school drill team and shallow prior to her pregnancy, began to become more sensitive and humble, though she still was upset that Van was the favorite for the Prom King title and she was not for the Queen.
In the third season, Kyra, Cheyenne's younger sister who continually makes fun of her, moves out, taking an emotional toll on Reba.
Reba does not support her choice because of her inability to commit to activities in the past, but Cheyenne insists she will be able to stick to her decision and pursues the career.
She volunteers at a homeless shelter and realizes that she wants to help people and changes her career choice to being a drug and alcohol counselor.
Van gets offered a scholarship to play football at USC, and they are excited about the idea of moving to California, but when Cheyenne experiences labor pains Reba successfully convinces them to go to the University of Houston where they will be close to family.
They find out that Van suspended his football scholarship because he was nervous and scared to fail, but Cheyenne and Reba are both angry that he made that decision without consulting his wife first.
They struggle financially and even apply for food stamps at one point, forcing Reba to take a job at Brock's office to help.
Cheyenne again tries to get Van to reconcile with his wealthy parents so they can help with finances, but they shower Elizabeth with extravagant gifts, and it becomes a battle of who can be the better grandparents between them and Reba.
Bored and not knowing what to do with himself, he finds other stuff to do like managing Kyra's band, playing online poker and attempting to train Jake in football.
When it is revealed that Brock owes $75,000 in back taxes, Van and Reba agree to buy his house and rent it out to him and Barbra Jean.
They are forced to temporarily move back in with Reba when a small fire is caused by Van's failed attempt to fix the heater.
She is angry at her dad Brock for leaving her mom and initially doesn't like Barbra Jean, making the same sarcastic remarks toward her that Reba does which gets her in trouble.
In season 2 her more devious side comes out: She lies to Reba about Barbra Jean giving Jake fast food (which turns out to be the truth even though she didn't realize it).
For the first four seasons of the show, a recurring theme of Kyra's storylines was her social life being unreasonably micromanage (and sometimes blatantly sabotaged) because her parents, including Barbra Jean, live in mortal fear that she will meet a boy and suffer the same fate as Cheyenne, despite her being the most intelligent of the children (probably even smarter than Brock).
Cheyenne also discovers that their strained relationship was started when she ruined Kyra's fifth birthday party by slamming one of her gifts into her cake out of jealousy.
Later, he's shown to have a devious side as well when he plays an elaborate Halloween joke on Reba, who greatly appreciates and applauds it, passing on the torch to him.
In the last season, she loses a large amount of weight and becomes a weather girl for a local station (she told people she was Stormy Clearweather).
In the episode "Every Picture Tells A Story," when Lori Ann says "men are pigs," Brock retorts with: "Well you must love bacon cause you keep marrying us."
