In the first Iron Man film (2008), Tony Stark is betrayed by someone close to him and it takes him (a demonstrable genius) several months to realize it. Why does he not realize as soon as he gets back that the conditions of his imprisonment were unusual (to say the least)?
Firstly, Obidiah Stane is the worst name for a villain that we are supposed to initially trust, but that is from the comics so it's understandable.
Secondly he remembers being videotaped for the kidnapper's demand video but when he gets back the video is not mentioned by anyone close to him (like Pepper, Rhody or Happy) nor is it mentioned in any news program or on youtube or anything, which for someone as famous as Tony Stark, one would think it would be around for him to see.
Thirdly: why doesn't he put together earlier that neither Pepper nor Happy had time to tell Obidiah about the miniature Arc reactor in his chest? Obidiah asks when he firsts arrives in LA and has been driven to Stark Industries to give the press conference?
Finally: why didn't anyone at Stark Industries give Tony the heads up that Obidiah was trying to force him out of the Board of SI? Doesn't he interact with anyone else at the company he is the head of?
