She might be in shock at first. After all, she was in a life - threatening situation. But then she could feel extremely grateful towards Edward and their relationship might grow stronger.
Bella would likely be very frightened during the car incident. Once Edward saves her, she'd be extremely relieved and probably feel even more attached to him. Edward, on the other hand, would be initially worried and focused on getting Bella to safety. After saving her, he might feel a sense of relief as well, but also a bit of that over - protective feeling that he often has for Bella.
In many such fanfictions, Edward might use his superhuman speed to reach Bella just in time. He could have sensed her danger through his vampire instincts and dashed to the cliff edge, grabbing her before she falls.
Edward could use his mind - reading ability. He reads Charlie's intentions and plans his moves accordingly. If Charlie is about to make a decision that Edward believes will be bad for Bella, he can intervene at the right time. He might also be able to manipulate the situation subtly so that Charlie changes his mind without realizing it.
Well, 'Bella to the Rescue' is another great one. It starts with Edward getting into a life - threatening situation. Bella, with her determination and courage, devises a plan to save him. The fanfic is interesting as it not only has the rescue part but also shows how their relationship evolves during and after the incident.
In many Twilight fanfictions, the scenario of Edward saving Bella from Jacob can be quite intense. It often plays on the complex love triangle dynamic. Edward might save Bella from Jacob in a physical altercation, perhaps when Jacob's wolf instincts get out of control. This could be a way to reaffirm Edward's role as Bella's protector in the eyes of the fans who are rooting for their relationship.
There are several themes. Firstly, the theme of heroism. Edward is depicted as a hero, bravely facing any danger to rescue Bella. Secondly, the theme of vulnerability. Bella's vulnerability makes her need Edward's protection, which adds to the drama. Thirdly, the theme of redemption can also be present. Sometimes Edward might be making up for past mistakes or perceived failures in protecting Bella, which gives the story an extra layer of depth.
