Re: Pepper Potts as Rescue
Mandarin could very well be in one of the news choppers. None of the pilots are shown, so afawk, LEGO might be right on the money about that. We can be about 99% certain that Mandy *sent* the choppers for sure; don't see why it would be a big deal if he happened to be tagging along to make sure the job is done right.
As for the sentient/drone armor --- there's plenty of scenes in the trailer that would indicate that at least one of the armors is remotely controlled. A likely scenario is that the Extremis armor comes with a nasty little implant that allows Mandarin/Killian to take control of it whenever they want. It would explain why Tony seems to be relieved to get out of the suit in the snow in the Super Bowl commercial, and why he'd choose to drag it across the snow and freeze his ass off instead of hop in and fly away. It would explain why Pepper's expression when she looks at the broken faceplate in the ruins is one of puzzlement instead of horror and anguish. It would explain why Iron Man attacks Air Force One and punches a hole through the fuselage. It would explain the scenes of the suit confronting Tony and Pepper in his own house a lot better than any tired old cliche "it was just a nightmare." And it would mean that neither Tony nor Pepper get killed in the drowning scene; just an empty husk that was probably trying to help kill the two during the mansion attack.
