As season three of Reba gets under way, single mom Reba Hart (Reba McEntire
) is shocked to learn that her younger daughter, Kyra (Scarlett Pomers
), intends to move in with her father, Brock (Christopher Rich
), and Brock's new young wife, Barbra Jean (Melissa Peterman
). But this bad news becomes good news when Kyra turns out to be a positive influence on the irresponsible and insensitive Brock, so much so that he and Reba bury the hatchet and become friends again. At the same time, the formerly vacuous Barbra Jean is showing signs of maturity, especially after bonding with Reba's older daughter, Cheyenne (Joanna Garcia). But there's trouble ahead for the two Hart families as the season draws to a close: Catching Reba and Brock in a friendly embrace, Barbra Jean suspects the worst -- and it looks like she might be right when Brock starts wondering if walking out on Reba was a mistake.
