Very beginning. If you know anything about camera work, you'd know that they're focusing on her walking through the door. She's wearing and holding the same stuff she did in other scenes. She's the point of that shot. Also listen to what they say, "Bruce coming back", "change is either a good thing or bad", "flip a coin". And the camera literally follows her as the guys check her out. It's "ironic" and foreshadowing.
They hint that Miranda Tate is in this thing all along, even with her dialogue. I guess you guys missed the Ra's Al Ghulesque crap she was spewing in her speeches at her party?
