Synopsis for "Bricks in the Wall"
Elsewhere in the city, Holly Robinson is accosted on the street by a man who tries to hire her as a prostitute. She kicks the man in the face, and continues on her way.
In Gotham City, Black Adam and Mary Marvel continue their conversation inside of the abandoned Kahndaqi embassy. Mary laments the recent loss of her powers, while Adam is still mourning the deaths of his wife and brother-in-law. He decides to bequeath all of his power unto Mary and speaks the name, "Shazam". The mystic lightning strikes and Mary Marvel transforms. She is now wearing a costume more akin to Black Adam's darker attire.
In the Multiversal Nexus, the Monitors continue to argue about the proper means of safeguarding the Multiverse. The one aggressive monitor cites several multiversal anomalies including Jason Todd, Donna Troy and Kyle Rayner.
In Keystone City, the Rogues are enjoying themselves at a penthouse party. The Pied Piper and the Trickster shy away from the others and have a conversation outside on the balcony.

Synopsis for "History of the Multiverse (Part III of XII)"
The Monitors continue their analysis of the history of the Multiverse, particularly as it relates to Earth-based matters. Having already reviewed information relating to the initial meeting between the heroes of Earth-One and Earth-Two, they study subsequent encounters, which took place on nearly a yearly basis. During one of such encounters, the heroes of each Earth discovered a third reality colloquially known as Earth-Three. As opposed to Earths One and Two, Earth-Three was dominated by an evil version of the Justice League known as the Crime Syndicate. The JLA and JSA later joined forces to stop the Anti-Matter Man from merging Earth-One with Earth-Two.
- The events from this issue coincide with events taking place in the Amazons Attack! limited series.
- All material revealed in the "History of the Multiverse" is in-line with material published prior to the 1985-86 Crisis on Infinite Earths limited series, and is no longer considered part of canon continuity. In Post-Crisis continuity, the Justice League of America and the Justice Society of America both existed in the same reality. By way of retcon, the two teams did team-up with one another on an annual basis, but the details concerning each encounter is different from that of published accounts and is historically ambiguous.
- "The History of the Multiverse" contains flashbacks of the first appearance of the Crime Syndicate from Justice League of America (Volume 1) #29 and Justice League of America (Volume 1) #30. One of the panels featured in this issue is a pastiche of the cover to Justice League of America #29. The story also contains a flashback of the JLA/JSA's encounter with the Anti-Matter Man from Justice League of America (Volume 1) #46 and Justice League of America (Volume 1) #47.
