This project would be a prequel all about Rainbow, many years before Black-ish.
If this second spinoff happens, however, it won’t simply see one of the characters depart to star in their own series.
The Black-ish universe expanded in a big way back in 2018 with the premiere of the Grown-ish spinoff, and now the folks at ABC are hoping that there’s still more mileage to get out of the Johnson family.
