Specifically issue #2 of the series, according to Geoff Johns.
â€œBrightest Dayâ€™ is about second chances. I think itâ€™s been obvious from day one that there are major plans for the heroes and villains from Aquaman to take center stage in the DC Universe, among many others, post-Blackest Night. â€˜Brightest Dayâ€™ is not a banner or a vague catch-all direction for the DC Universe, it is a story. Nor is â€˜Brightest Dayâ€™ a sign that the DC Universe is going to be all about â€˜light and brightyâ€™ superheroes. Some second chances work outâ€¦some donâ€™t.â€
