"Around the time we started breaking the story, Walmart, Target and a lot of the other big box retailers had stopped locking the Black haircare products up behind the glass case, which was something that a lot of my colleagues -- if you've never bought those products -- you probably haven't been paying attention to. That was the reality for being a Black customer at the time," co-producer Dayo Adesokan tells ET of writing Thursday's "challenging" episode. "That seemed like a natural way to enter the story. And then from there, trying to figure out where the conversations would go within the world of Cloud 9, within the world of Superstore. Just trying to think of a way to tell a story about race that didn't feel like something that had been done on TV before, that didn't feel like an afterschool special, so to speak. We were very careful about avoiding some of the common pitfalls that I think other shows in the past have fallen into when trying to tell those stories."
