Hit a passage where the heroine remembers, with some resentment, how her parents had forced her to submit to an unjust demand from her uncle.
The thing is that I put in that scene in a later bit, and probably should put in the parents actually forcing her. Seeing it in action, however, would make them look worse. (Perhaps because from her memory the reader knows it's colored by her thoughts?)
Hmm. . . maybe I can make her uncle do that, and her parents just acquiesce. Which gives the advantage that his saying she must do it is quicker than depicting the force. Plus they aren't wonderful parents but I didn't want to make them quite that terrible.
