People, this is the way it works in the comics. Audiences understand that. They *expect* that. The tired, lame old excuse about "omg advertising for Avengers movie!!!!" no longer works. It's the MCU, and just like the comics, characters weave in and out of each other's stories.
The comics are different. The comics give you about 2-3 times the story you get from a movie every year, while you get a movie once in three years. So you can afford to feature guest appearances every now and then.
Black Widow is fine. She is relevant, though not necessary to the storyline in question. Hawkeye is taking it too far.
I like him too and would like to see him again before Avengers 2, but why not do it in Iron Man 3, or Ant Man?
