Nah. Not sure which movies you were watching but at the end of Phase 1 he was still struggling to come to terms with everything that had happened to him, which is a given since what has happened to him has pretty much never happened to anyone ever before, not even in-universe with respect to the MCU. That, and the fact that he has to deal with shadowy Government organizations were both pretty well set up and it was very obvious character development there. And in WS, it becomes even more obvious to him that in spite of Fury telling him all about SHIELD, it was still a very shadowy organization and the reveal of HYDRA infiltration was simply the last straw for him to start taking decisions on his own instead of simply following the chain of command. The conversation with Falcon in the Veterans' building set it up beautifully. And that leads in directly to everything he does both in AoU and CW. As I said, this is the most organic, effective, brilliant, believable and best character development across a trilogy (or 5 movies if you wanna count the event movies) for any CB based SH character ever. I would love to think what makes you think otherwise from any of these movies unless you had made up your mind to think this way before even watching these movies.
