"Mythologies become exhausting burdens, from a writer’s perspective. If you look deep into The X-Files, which we bring up a lot in the room as something we’re just terrified of, or late in the game with Buffy, as much as I love that show, things get complicated and it’s hard. It becomes less about the fun of why you fell in love with that show, in the first place, and more about servicing all of these storylines."
