During an exclusive interview with Us Weekly, Reba McEntire, Belissa Escobedo, Melissa Peterman, Pablo Castelblanco, Rex Linn and Tokala Black Elk teased what to expect from the new season including the scenarios they are pitching to the writers. "We have a dream of seeing flashbacks to Happy," Castelblanco said about Bobbie (McEntire) and Isabella's (Escobedo) late father. "Belissa really wants Kevin Costner." Peterman, 54, cosigned the idea of Costner joining the NBC sitcom.
