Showrunner Jonathan Nolan said the writing team decided to make Root a prominent character mainly because of the theme music composer Ramin Djawadi wrote for her. In an interview, he once said "Ramin had written this theme for Root and it was amazing. It's a really fun, mysterious character, but we really wanted to hear that theme again! So when we came back to the [Season 1] finale again, we know where we wanted to go with the character".
