"Supergirl: My hands still shake when I remember Brainiac's "collection" of Krypton. I want to give the world he stole a second chance. But bonding with Brainiac's ship is too risky. I need a safer way to restore our cities. I'm so glad for the Justice League's help. Barry, Professor Stein--they've already taught me so much. Every day, we get closer to reversing Brainiac's collection process. When we do, we'll pick the right star system. What Brainiac ruined will be reborn--Argo City and Kandor, twin cities, survivors. I couldn't save Kal-El. But I will save our people."
