Notably,black-ish’s season 4 finale seemed to draw from the real-life couple’s experience as it showed Dre and Bow’s marital struggles.

In a 2018 interview withEntertainment Weekly, Rania said she told her husband, “I think you owe it to your viewers to show this.”

She added, “Because so many of the stories are situations very exact to our life, Kenya cannot help as a writer but to make the character of Bow more prominent [and] important.”

Kenya has also spoken about the marriage problems his characters face, saying that he wanted to portray real-world situations on screen.

“When I was growing up, I never saw couples fight on the family sitcoms I loved to watch,” he toldEWin 2018.

“Subsequently, when tough times arose in my own relationship, I wasn’t prepared and felt so isolated and alone,” he continued. “Marital issues weren’t a part of the narrative that television told me was a ‘working relationship.'”

Kenya is also a producer on the sitcom’s spin-offgrown-ishand was a writer on the 2017 movieGirls Trip.
