The Hanged man tells him that there was a battle with a time-traveling supervillian named Time Keeper that broke the time continuum and reality, that the heroes fought and won, but there has been some changes after the reconstruction of reality, and this woman was his wife in the precedent version of reality because her grandparents never met. The Hanged man offers to erase theese dreams but Michael decdes to keep the dream so he can still remember her even though he never really knew her.

The above description applies to the half issue.

The ongoing series is the finest comic I have ever read and should be considered a college textbook when it comes to graphic storytelling. From the bottom of my heart I recommend this series.
