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.

Reba decides to go back to work, and she takes a job as a substitute teacher at Cheyenne's high school. But when she discourages two teens from considering marriage, her advice is misunderstood and gets her in trouble with the school.

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.

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.
