The fifth-season opener of Full House finds Jesse (John Stamos) returning from his band tour, Becky (Lisa Loughlin) awaiting the birth of her baby, Michelle (played by the Olsen twins) preparing to start kindergarten, and DJ (Candace Cameron) on the threshold of beginning high school. When Becky finds out she is going to have twins, Jesse reacts to the news in a surprisingly negative fashion. Meanwhile, Steph develops a crush on her first male teacher, Mr. Lowry (Philip Levien). With this episode, former recurring actor Andrea Barber becomes a regular in the role of Kimmy, and Tahj Mowry makes his first appearance as Michelle's new best friend Teddy. ~ Hal Erickson, Rovi
