The Gwen-MJ analogy is the most likely one, imho. I keep going back to the love triangle, which I know some of you don't like, but it's definitely a tried and true selling point for just about any movie. And if Sharon gets the white jumpsuit, with Widow still in the black one, the symbolism is blatant enough for even the youngest child to understand. Steve has to choose between good girl and bad girl....probably making his final choice in AoU.
