Was re watching Iron Man this afternoon (oh, hush) and noticed that when Stane takes Tony's reactor, he talks about putting power back in "the right hands: our hands", which I'd never noticed before. They can't possibly have planned TWS then, right? Given that he had no visible cabal in the film, I assume that it originally referred to the war hungry right wing white men who run the country but I love that I can now tie it back into serious conspiracy(tm) in my head.
Also, it adds an extra dimension to Tony's decision to tell the truth at the end rather than SHIELD's story - with a secret, they would have had a hold on him, but instead he shows that he can't be easily controlled straight off.
I do love plot twists that make you think about old canon in a new light.
