How come in Iron Man 3, people are treating Tony Stark like he was crazy, talking about vortexes and Aliens. When people bring it up, he begins to have an anxiety attack.
In the Avengers, he never seemed any different than he is in any situation. Also, didn't this event happen in a major metropolis, with possibly thousands of witnesses.
Why did Iron Man 3 go this route making it seem like an imagined event that makes him have panic attacks?
