After the destruction of the Anti-Monitor by Kal-L, Superboy-Prime joins Alexander Luthor, Jr., of Earth-Three, Kal-L, and his wife Lois Lane in a "paradise dimension". In that dimension, Superboy-Prime secludes himself from the others, using crystals to replay events from his life on Earth Prime. Superboy-Prime becomes frustrated and angry. He tries to reach out to Kal-L, whose attention is focused on Lois's failing health. Alexander comes to believe that the reason behind Lois's failing health is the paradise dimension itself, and he persuades Superboy-Prime to help him return to reality by showing Superboy-Prime the negative aspects of the post-"Crisis" Earth. Superboy-Prime hesitates until he overhears Kal-L say, "I wish this world would let him grow up. He'll "never" be Superman here". Finally, Alexander shows him the deaths of his parents and girlfriend in a car accident on the post-"Crisis" Earth.
