Separated at Birth?

Is it just Crusty or was there some awful tragedy in our recent history, when a mother left hospital with only one child instead of two?

This would certainly explain many things; chaos and terror in the heart of Gotham City and the same throughout Her Majesty's realm. We've also just seen Catty Woman resign so there is another thing we must take into account.

Crusty hopes they are reunited very soon!
