In Avengers: Age of Ultron movie,
There's a scene in which Steve Rogers and Tony Stark are chopping wood. Then, Hawkeye's wife comes and asks Tony to fix the tractor. But it turns out to be Nick Fury near the tractor.
Now, the question is: Why did Nick Fury do this? Wasn't Captain America trustworthy? Couldn't he talk to Tony in front of Steve?
In Captain America: Winter Soldier movie, just after his death, Nick Fury trusted Captain America. What happened now?
