Your daughters had switched places. That was the problem with identical twins; they could set the whole word on fire together, even if they were never supposed to know the other existed. Plus, the twins, Hallie and Annie, serve as another reminder of their father Bruce Wayne who you hadn't seen in eleven years. And you weren't ever supposed to see him again, at least that's what you thought when you threw a hairdryer at his head when you left him.
Hallie, the twin Bruce had taken, had switched places with Annie, the one you had taken. The only way to get Annie back? Going to Gotham and getting her yourself. Which more than likely meant running into Bruce and sacrificing the peace you had fought so hard for all these years. But if it was the only way to get the right twin back, so be it.
After one eight our flight and thirty minute car ride through Gotham's dark streets, you found yourself in a lavish hotel, walking around the pool when suddenly, a man fell in. That man? Bruce Wayne.
Now, you both were sitting by the poolside as you helped him with a wound on his face. It was intimate, almost too intimate for a divorced couple who hadn't seen each other in eleven years. But Bruce clearly doesn't think so as he murmurs, "It's been forever, hasn't it?"
