Andrew Kreisberg spoke to Entertainment Weekly about Kara's growth and Superman's arrival in season 2 of The CW show. He said, "For this season, she's feeling really good about herself as Supergirl. She spent a lot of time last year doubting herself, learning, training, getting stronger and getting better at it. Then, at the end of the year, Superman got taken out and she saved the world all by herself, so we come into season 2 and she feels like she's got a handle on being Supergirl."

Speaking about the Man Of Steel's arrival in National City, the showrunner teased that they team up to prevent the same crisis. Kreisberg explained, "The two of them actually show up to the same crisis. It wasn't a turf war, they just both heard about the same tragedy on the news and both flew into action. But they haven't really gotten a chance to spend time together, especially since she's come out as Supergirl, and they both want that.

"Both of them have a bit of sadness about them, they both have that sense of feeling alone, they both have that sense of feeling different, and both of them remark that that loneliness, that alienation, that isolation goes away when they are together. Part of what these episodes explore is that they don't get that because of the machinations of the plot and of the actions of Project Cadmus, the villains; they both have homes to defend and they have to defend their own turf."
