Usually this kind of personal journey is explored on the small screen with a younger character, most often with teens in coming-of-age stories. But it was important for the Supergirl producers to be true to life and explore this with an adult character.
“After talking to [executive producer] Greg Berlanti and doing some research on my own, anecdotally it seems like people who come out later in life come out because they’ve met someone,” Kreisberg says. “There’s a specific person for whom they’ve fallen. The idea that Alex who never really had a strong romantic connection with anybody and had come to dismiss it, and then meets Maggie and has her world turned upside down, it seems like interesting territory to us, that it wasn’t about a young teenager coming to grips with it. It was somebody who was an adult and in some ways had more to overcome on an internal level to get to the point where she could recognize that she has these feelings.” (x)
