[Son of Coul]

Nick Fury and Black Widow pop up in the comics for some deus ex machina and just the sake of it all the time. Wasn't an ad for The Avengers, just warming up for the many future crossovers of the MCU in general. You could tell they had fun putting them in there, something they could never do before. I guess some people (the fans, ironically) didn't have fun watching them. I know I did.
