But Reba comes to the rescue with a plan for the feuding pair to reconnect and have some time away from their crying infant.

Reba loves to make fun of Barbra Jean but vows to suck it up for Kyra's sake; however her plan backfires during Jakes birthday party when Barbra Jean starts thowing out a few insults of her own. Meanwhile, Brock shows up to the party fresh from his first Botex treatment.

When Reba goes to work full-time for Brock's rival, Jake starts referring to Barbra Jean as ""Mommy."" Meanwhile, Van gets a new job working as a gardener, and Cheyenne can't understand why he'd rather spend time with his fellow ""lawn jockeys"" than the in-crowd.

In hopes of resuscitating her non-existent love life, Reba hits the bar scene with her friend Lori Ann but is mortified when they run into Brock, Barbra Jean, Cheyenne and Van on a double date. Cheyenne finally convinces a reluctant Reba to try speed dating, and everyone is surprised when she actually makes a love connection.

A near-death experience causes Reba to put her personal affairs in order and write a will.

Kyra's fine grades in social studies have earned her an invitation to study in England for the summer, but when Cheyenne announces that she must attend summer school to remain a full-time student, Reba discovers that her financial situation will only allow her to assist one of the girls.
