Reba and her family go to therapy to talk about the recent breakup of her marriage to dentist husband Brock, but what Reba doesn't know is that her 17-year-old daughter, Cheyenne, also has an unexpected announcement.

Cheyenne and Van come home from their honeymoon in Galveston and have to deal with returning to school--married. Meanwhile, Reba adjusts the house for their new living arrangements, but not everyone is as ready to accept the newlyweds.

Van moves his belongings into his and Cheyenne's room, and Reba and Kyra are shocked when Cheyenne accepts the mess, which includes a large neon sign, 12 pairs of sneakers, exercise equipment and a Dallas Cowboy Cheerleaders poster. Meanwhile, Jake has his first visitation with his father, and Reba makes a discovery about herself.

Cheyenne has morning sickness and tries to hide it from Van; Reba learns that Jake's friend isn't allowed to sleep over because his mother disapproves of the Harts' dysfunctional lifestyle.

Van gets a "kidnap breakfast," a tradition that includes the drill team making the football player of the week an early morning meal. Meanwhile, Reba decides to host the Wildcat pregame dinner for the team and everything goes well until Barbra Jean discovers the potato salad.

When Reba calls a plumber to fix a leaky faucet, their encounter leads to a date at the hardware store. Meanwhile, Cheyenne decides that she's going to "moon" Van and his teammates.

Cheyenne wants to be treated like an adult and decides to get an apartment--until she sees how much they cost. Meanwhile, it looks like Van's parents are trying to reconcile with the young married couple and even offer a housing suggestion.

Reba helps tutor Van when being on the football team takes up too much of his time and his history grade starts to slip. Meanwhile, Kyra is attracted to a tuba player in the school band.

Reba decides that she wants to move Brock's things out of the house, so she has a garage sale with her friend Lori Ann. Meanwhile, Cheyenne feels the baby kick for the first time.

Brock springs a surprise on Reba regarding his upcoming wedding, and Reba has her credit card rejected when she goes out to lunch with Lori-Ann.

Reba's family is delighted when her parents stop by for the weekend, and a special lunch is planned to celebrate their anniversary. Meanwhile, Reba's mom, Helen, and Barbra Jean hit it off and the ladies go shopping together.

Brock finds out that his estranged father has passed away, and he asks Reba to help him with the funeral plans. Meanwhile, Cheyenne goes to the doctor's office for an ultrasound.

With Reba and Brock's divorce final, Lori Ann looks up Reba's old college boyfriend and sets the pair up for a date. All is well--until Reba recalls why she originally dumped him.

It's Brock and Barbra Jean's wedding day and the whole family gets ready for the event except Reba, who declines the invitation. Still, she ends up mending dresses for the nuptials and may get stuck being part of the festivities after all.

After Van is named his football team's Player of the Year, Reba tries to get his parents to attend an event in his honor. Unfortunately, her efforts don't go as planned and she ends up with a new houseguest.

Reba gets roped into going to Lamaze class with Van when Cheyenne can't attend a session. To make matters worse, Barbra Jean and Brock show up at the same meeting.

Reba throws a baby shower for Cheyenne and gives her a homemade present: a quilt sewn from Cheyenne's own baby clothes. But when Brock runs out and buys the parents-to-be a car without consulting Reba, she has a bit of a problem with it.

Cheyenne thinks that she is in labor, so everyone rushes to the hospital. But Barbra Jean's the one who's in for more than expected when the fellow mom-to-be makes her way to the maternity ward.

Cheyenne and Van have been nominated for prom king and queen, and while the popular Van's a shoo-in, Cheyenne isn't , so Van does the political math and comes up with an electoral strategy of appealing to "alienated" students (i.e., nerds).

Brock promises Jake that he will build him a tree house, but he gets preoccupied with his newborn and breaks his word, so Reba has to open up the toolbox to lend a hand.

Cheyenne and Van get ready for graduation as the mom-to-be tries to hide her contractions because she wants to get her diploma in person.
