In Iron Man 3, there is an antagonist by the name of Aldrich Killian who is on Extremis medication.
- When Aldrich meets Pepper Potts in her office, he shows a live, 3D view of his own brain, complete with 'hole' that indicates we were meant for further evolution. He implies that Extremis is the drug that will fill that hole with 'new potential' mostly in the form of repairing health.
- Aldrich is taking Extremis, and has all the powers that are associated with it (including elevating his own body temperature, fast repair from injury, and ..breathing fire(?!?)).
- Between 1999 and when we later see him in the movie, he has been cured of whatever it was that caused his stooped posture and awkward movements. He claims it is down to "5 years of physical therapy" but we are left to suspect it was actually Extremis that caused the change.
So I figure either the first or third statement above must be wrong. Either he actually did have physical therapy (rather than Extremis) to cure his ailment, or Extremis use did not physically fill the hole in the brain that Pepper saw.
Any pointers over where I've gone wrong?
