Because I'm the sort of person that can't stop picking at a scab... still more Catwoman origin stuff, and the final fate of Maggie.
1987 - Batman: Year One 1989 - Her Sister's Keeper, seen in my other post. Regarding Catwoman's family, this story stated that her mother had run away when Selina was young. Selina ran away, presumably not long after. Her sister, Maggie, grew up to become a nun. When Selina becomes Catwoman she runs into her sister and discovers their father has been dead for two months. 1994 - Catwoman 0 aka Cat Shadows. In this version of the story, Selina's mother commits suicide when Selina is very young. Her alcoholic father dies shortly after. Selina is all alone. There is no sister. 2000 - writer Bronwyn Carlton gives a... different take on Selina's childhood. The door is open for a sister to exist. 2002 - Maggie returns, no longer a nun, some of Sister's Keeper is referenced in a roundabout way, but at the same time we're told that Selina was orphaned when very young, so some of Cat Shadows is there too. Maggie gets kidnapped again, and plays a familiar role.
First, some Cat Shadows
The Bronwyn Carlton retelling
I think I hate every single thing in Carlton's issues... except that awesome shot of the girl on fire, all "y u do dis?"
It's a run begging for MST3K treatment.
From Brubaker's run, Maggie returns, no longer a nun and with a husband. She gets kidnapped by an enemy of Selina's, of course. That's why she exists.
Selina saves Maggie, but her husband doesn't make it.
