Synopsis:

The heroes all gather back in the Justice Cave, but discover that the re-aging device retrived by Doiby Dickles and the JSA is not enough to restore everyone to their correct ages, so they go in search of Klarion, in order to combine magic with science, having some leverage over him since Deadman is in possession of the witch boy's familiar, Teekl. After doing battle with a cadre of l'il villains and animated poxy-monsters, the heroes arrive at the Agenda's alaskan headquarters, where Wonder Woman, Wonder Girl, Superboy and Superman are being held prisoner.

The Point Men discover that they are being used by the Contessa and side with the heroes, who are eventually able to coerce Klarion into restoring the natural ages of everyone on Earth. Merry, girl of 1000 Gimmicks, a member of Old Justice, is prepared now to go on camera in tentative support of Young Justice and similar teen heroes.

However, things are far from over, as the Contessa now has samples of Kryptonian and Amazonian DNA and a de-aged Lobo appears on Earth, rather annoyed with Klarion.
