In which I make a few logical deductions about what we can look forward to.
For the first time since Kimiyo Hoshi was depowered and left for dead in Green Arrow #55 we have a sighting of Dr Light II that cannot be put down to a flashback or awkward resheduling of timelines. Unless Batman, Superman, and Wonder Woman are all so out of touch with the current superhero situation that they are unaware of what happened to her, then it's safe to say that Kimiyo is alive and well, and back in action.
In fact the dialogue here suggests not only that they are aware of what became of her, but that subsequent events have occured that we haven't been been shown yet.
Consider; Superman doesn't want her in the Justice League because she is too scary. Retired heroine, single mother, doctor (or business executive according to some), last seen powereless and symbolically raped is too scary for Superman to invite to the Justice League.
You think he maybe knows something we don't?
Extrapolation: Kimiyo has done something scary. Kimiyo has her powers back.
Deduction: Kimiyo done something scary to evil rapist bastard Arthur Light, resolving the plot lines left dangling for the last year and establishing her as someone not to mess with.
Extrapolation 2: since this important plot development has not yet been seen or previously referred to in a One Year Later title it seems reasonable to look for it in 52.
Okay, it would be nice to see a Doctor Light miniseries, but if we are going to get anything that does this story justice then I'll be happy.
