King Edward might become more protective and less focused on his kingly duties at first. As the story progresses, he could learn to balance his love for Bella and the baby with his responsibilities. Bella could become more confident in her role as a future mother and a queen - like figure in the kingdom.
In some fanfiction, Edward might be mean to Bella to create drama. Writers may use this as a plot device to add tension to their relationship. For example, it could be due to some misunderstanding or an external threat that makes Edward act out of character and be mean.
For Edward, there's likely a mix of relief and fear. Relief because he's finally expressing his deep love for Bella, but fear because he's exposing his true feelings and also worried about how this will change things. For Bella, she's probably mostly filled with excitement and a bit of shock. The excitement of this new level of intimacy with Edward, and the shock that this moment she might have dreamed of is actually happening.
Alice is often quite popular. She has the ability to see the future, which can add a lot of interesting twists to the story. For example, she might see a danger coming towards Bella and Edward and try to prevent it. Her quirky personality also makes her a favorite among fans.
Carlisle is another character that many might like. As Edward's father figure, he can offer wisdom and guidance to the newlywed couple. His calm and ethical nature can play an important role in helping Edward and Bella navigate any difficulties that come up in their married life, such as dealing with vampire politics or ethical dilemmas.
At first, it might be a bit rocky. Since the marriage is by treaty, they may be a bit wary of each other. But as they start spending time together, they could begin to discover common interests. For instance, they might both be interested in a particular type of literature or music, which helps to break the ice.
Edward could start by gently waking Bella up from the nightmare. Then, he would wrap his arms around her and sing a soft lullaby that he might have learned over the years. He would stroke her hair and look into her eyes, assuring her that it was just a bad dream and that he is right there with her, and that no harm will come to her as long as he is around.
Yes, there are likely such fanfictions out there. Fanfiction platforms host a wide variety of stories based on different interpretations of characters and relationships. However, these often deviate from the original story's canon.
One example could be that Edward constantly criticizes Bella's choices in the fanfiction. He might not like her friends or the activities she's involved in and be very vocal about it in a mean way.
Definitely not. Fanfiction is usually about exploring new aspects of the characters and their relationships in a tasteful and meaningful manner. This kind of storyline is not in line with the values and expectations of the fanfiction community.
