Re: In hindsight what changes would you do
There was a more persistent internet rumor that Nolan was looking for Sarah Essen at some point.
My "hindsight wish list" involves Sarah Essen. She has tension with Gordon leading up to Bane's takeover, they wind up making sweet love during the occupation, and at the end on the roof of police headquarters she shows Gordon a positive pregnancy test.
This would give Gordon a happy ending similar to Bruce.
