With Supergirl ending after six seasons, it isn't just the Girl of Steel's story that is wrapping up. All of the Super Friends are going on their own final journeys, and for Nia Nal/Dreamer (Nicole Maines), that journey means working to fully develop her powers. Developing and understanding those powers is something that has been a challenge for Nia since coming into them coincided with the sudden death of her mother who ordinarily would have mentored her. It puts Nia in a vulnerable position, but according to Maines, it's also the beginning of Nia's final, full-circle journey.
