In "The Groupie", Kara needs attention and her husband won't give it to her.
That's too bad for him, because when he leaves her alone at a concert from her favorite band, she is called onstage and serenaded. After the final number, the band invites her backstage, for what she thinks will be an autograph session.
What ends up taking place is an opportunity for Kara to sing into all of their microphones, as she shows why she's the best groupie that they have ever come across.
