Earth-1's Johnny Thunder reveals the origin behind the 2nd Canary, placed in limbo by Earth-2's Johnny Thunder at the Earth-1 Superman's request following their battle vs. Aquarius, since Aquarius's radiation was killing her as she crossed to Earth-1 after her husband's death. She was then replaced by her daughter, whose memory had been replaced by hers. The heroes defeat the Earth-1 Thunder alongside the Earth-2 counterpart, while the revived JLA aid their JSA allies on Earth-1. The current Canary has her original memory restored and leaves with the Earth-1 Superman back to Earth-1.
