I have a interesting theory I like to share and it connects things we have seen from The Dark Knight Rises. Gordon is in a hospital and it looks like te guy he is talking too has a black mask over his head, simalar to the one Bruce wore in Batman Begins. I saw a set photo where there was a guy who has a black mask on looking like he is dropping out of the hospital window. Then in trailer 2 you see someone falling. In trailer 2 you see John Blake bursting through what looks to me a hospital door. SO to me it sounds like Bruce visited Gordon with the black mask over his face because he probably told Gordon he was Batman but didnt want to come in as Bruce Wayne in order to keep his identity secret. Then John Blake probably has been informed somehow that someone is in the room with Gordon and thats where that part in trailer 2 comes in when he bursts through the door. Then John Blake gets in the room Bruce Wayne with the mask over his head makes that escape through the window and thats where that set photo comes in and that part of what someone looks like they are falling in trailer 2. What do you guys think? The set photo link is down below.
