One possible plot could be that Bella discovers Edward's betrayal through a series of small clues. For example, she might notice that Edward is spending a lot of time with Jessica and being overly secretive about it. Then she starts to investigate and uncovers the truth, which leads to a huge emotional breakdown for her.
Jessica Chambers was a victim in this story. She was a young woman who unfortunately became the center of a very tragic and mysterious case when she was found burned in a vehicle.
Jessica Lynch was a U.S. soldier. Her story was initially misrepresented by the media. In fact, she was injured in a vehicle accident during the Iraq War. Later, she was captured by Iraqi forces. The real heroism lies in her survival and recovery from the ordeal, rather than the over - hyped 'action - hero' narrative that was initially spread.
