The ballerinas could be a reference to Black Widow being a ballerina in the comics. Thor is seen dropping his hammer-Could he become unworthy? There is a scene that appears to be set in World War 2. That, plus the ballerinas, Thor (maybe) becoming unworthy, and Hulk and Thor becoming aggressive and fighting Tony could mean that Ultron or Scarlet Witch is messing with the Avengers minds. Several scenes of Black Widow and Bruce Banner together. That could mean they are dating. In some scenes, they appear to be holding hands.
