"Agatha All Along" Creator Jac Schaeffer Confirmed This Controversial Fan Theory, And 11 Other Behind-The-Scenes Secrets We Learned From The Cast

Speaking on the theory, Jac joked, "When we were developing it, we — executive producer Mary Livanos and I — got a lot of questions. 'Who is the dad, who is the dad?' And we were like, 'Why you wanna know?'" Kathryn, who played opposite Aubrey Plaza's Rio in the show, chimed in, "They don't need dads!" Jac continued, "That was just something that...we didn't wanna answer the hows and whys of it, because it's witches, but it was just something that was important to the writers and to me and just felt like something special. So it was really lovely to have something that the fans said that we can confirm."
