"That whole week was one of the funniest weeks in the (writers) room," executive producer Gloria Calderón Kellett tells TVLine of the opening to last night's episode. "We had a lot of fun talking about that, and that opening scene is a scene I (originally) pitched to (co-showrunner) Mike Royce three years ago. We just needed to find the story to support doing it.”
