Hear me a little;For I have only been silent so longAnd given way unto this course of fortune....By noting of the lady I have mark'dA thousand blushing apparitions
Thinking about social codes and how to challenge them, it is evident that Hero was put in a situation where she was powerless. In this situation, (whether intended or unintended by Shakespeare) Friar Francis challenges the social codes of expectations and reactions towards men and women. Claudio refused to marry Hero because he believed she was unfaithful (against social expectations of women) and Hero was unable to defend herself because she was a woman (and nobody believed her). In these lines, Friar Francis stands up for Hero, saying that she appears innocent despite what Claudio, Don Pedro, and Don John claimed of her. This challenges the social codes because it gives a little bit of power back to Hero when he says that he believes Hero(a woman) over Claudio (a man).
