Her relationship with Ronnie also extends to their work on the town council-work they share with Roland, who sometimes frustrates Moira. While a part of this group, Moira also forms bonds with fellow members Ronnie Lee and Twyla Sands. This relationship grows when Moira joins the Jazzagals, a singing group founded by Jocelyn. Moira is reluctant to return this kindness, but by the end of the first season displays glimmers of gratitude when she gifts Jocelyn one of her designer fur coats. Jocelyn and her husband, mayor Roland Schitt, are some of the first people to show the Roses hospitality when they move to Schitt's Creek. Outside of her family, Moira's closest connections are with the mayor's wife, high school teacher Jocelyn Schitt and members of the Jazzagals a cappella group. This pairing continuously highlights Moira's ability to be loving and kind even when she has difficulty expressing those feelings to others. Moira's closest confidant is her husband, Johnny, whose "straight man" demeanor balances and steadies her bombastic tendencies. Her son, David, is in many ways her favored child, but as her time in Schitt's Creek increases, she also begins to establish a relationship with her daughter, Alexis. Her attempts at mothering are often awkward (such as the time she forgot her daughter's middle name) or otherwise poorly executed. Moira is the matriarch of the Rose family, and a previously inattentive mother who often struggled to connect with and care for her now adult children. The two married sometime later and have remained married for many years.
During her time as an actress, Moira met her future husband while cutting the ribbon at the grand opening of one of his video rental stores. Moira would go on to act in a number of theatre productions before being cast in Sunrise Bay, where she stayed for six and a half seasons. Her big acting break came when she was cast as Sally Bowles in a production Cabaret after the director spotted her working at a local gas station deli. She grew up in a small town similar to Schitt's Creek, where she took pride in her self-sufficiency and ability to master the basics of everyday living. Moira has one known younger sister named Dee Dee. She and her husband, Johnny Rose, the former CEO of Rose Video, the second-largest video rental company in North America, share two adult children, David and Alexis. Moira Rose is a formerly wealthy daytime soap star, most known for her role as Vivien Blake on Sunrise Bay.
But now Moira has received her own slap in the face, having lost her fortune and most of her personal belongings, except for an extensive, and expensive, collection of eccentric outfits and individually named wigs. Once she was the former star of a once-popular daytime soap opera, Sunrise Bay, where Moira's character Vivien Blake was best known for boldly slapping other characters when they got out of line.
