Why can’t this just be a Catwoman-Umberto roadtrip, or – more Hellhound! more deathtraps! more pages lost to explaining plot elements for the Batman story going on!
The virus storyline Batman is partaking in continues elsewhere, but this is it for Catwoman’s involvement/not involvement (how would Batman like it if another super butted into ‘his’ story arc about the return of his archnemesis??). And the last we’ll see of Hellhound and his many many knives.
Catwoman and her crew and the Bat gang belong to DC Comics, and Escher Girls is the creation of the awesome Ami Angelwings. And the Escher Girls bingo card belongs to the Escher Girls fan who created it.
