Bella could develop a stronger sense of survival. In the face of the mob's threat, she has to constantly be on the lookout for danger. This would make her more aware of her surroundings and better at finding ways to stay alive. For instance, she might learn how to hide, find safe places to stay, and avoid being detected. As she overcomes various challenges during her escape, she may also gain more confidence in her abilities. Initially, she might be very scared and unsure, but as she manages to evade the mob's pursuit, she realizes that she is capable of much more than she thought.
Her relationships with others could also change. Since she is running away from the mob, she may have to cut off contact with some people for their safety. This could make her more cautious about who she trusts. On the other hand, she might also form new alliances or friendships with people who help her during her escape. These new relationships could teach her different values and ways of life. Also, her view of the world could shift. She used to live a relatively normal life, but now she is in a world full of danger and secrecy. This new experience could make her more cynical or, conversely, more determined to fight against the mob and bring justice.
