The Skarsgårds

It’s post-traumatic stress, and Rhodey can tell.

Tony has really retreated after the events of ‘The Avengers’ into his workshop, where he’s building advanced versions of his suits. He has now even has a version of the suit that can latch onto him in individual pieces … anytime, anywhere. As he starts to realize, it’s basically because he doesn’t want to be out of the suit. He’s seen a lot of things in ‘Avengers’ and has encountered a lot of powerful people, much more powerful than he is, and has made a lot of enemies. 

“He’s been building nothing but suits and suits and suits and suits- it’s an obsession.”- Joss Whedon
