You know what the sweetest/creepiest/most hilarious relationship in comics is? It's not any of the romantic pairings you see out there. And it's not even any real paternal connection. Truly, the most brilliant character relationship in comics is the really strange relationship that Bane and Scandal Savage have in Secret Six.
Did your read the Suicide Squad "back from the dead" one shot? It was really good (it's Ostrander and Simone, how could it not be?). And there was a fantastic bit of Bane/Scandal interaction in there.
It's a very weird relationship. Bane -- the guy who never had any parents -- trying to be a father figure to the woman who had the worst father in history (and pre-history). And the strangest thing about it is how it seems to work. At first it seemed kind of off but now it seems bizarrely natural.
If Geoff Johns writes the best "epics" for DC then Gail Simone writes the best relationships. Really, all the relationships between the various characters in Secret Six are fantastic. I just happen to like the Bane/Scandal one the best.
