Andrew Kreisberg even went on to say:

[Indigo] looks badass, she’s going to look awesome. And she definitely won’t look just like Laura. … Being one aspect of the Brainiac program, she comes in through computers, so Winn is actively involved in that episode. She was one of the Fort Rozz prisoners, so how she got there and what she’s been doing on Earth is part of the surprise of the episode
