In some fanfictions, if Bella starts to show signs of becoming a vampire too quickly or in an unexpected way due to her relationship with Edward, Carlisle might be troubled. He could be worried about the implications this has for the family and for Bella herself. So, he might confront Bella about the situation and try to find a solution to prevent any negative outcomes.
One example could be when Bella tries to learn more about vampire powers on her own without Carlisle's permission. Carlisle, being very cautious about keeping their existence a secret, would not be happy with this as it could lead to unwanted exposure.
It could be that Bella gets in trouble with Carlisle because she disobeyed one of his rules. For instance, if she went out alone at night in a dangerous area where there are other vampires who might not be as friendly as the Cullens. Carlisle, being the patriarch of the family, would be concerned about her safety and the safety of the family as a whole. So, he might restrict her activities or give her a stern talking - to.
Perhaps Bella is being bullied at school in the fanfiction. Then, a group of her classmates who are usually quiet might stand up for her. They could form a support group for her, and together they come up with strategies to stop the bully, like reporting to the teachers or using social media to expose the bully's actions.
One idea could be that Bella is scraped while trying to protect Carlisle from a rogue vampire. Carlisle is then filled with gratitude and takes extra care of her. This event could spark a new friendship that makes the other Cullens a bit jealous or confused.
Sure. In one fanfic, Renesmee got into trouble when she wandered too far from home on her own. She was discovered by a group of nomadic vampires who didn't know about her special status. They thought she was an ordinary human child at first and were about to attack her. Luckily, her family sensed the danger and came to her rescue just in time.
In such a fanfiction, perhaps Bella could be in a minor accident (getting scraped) and Carlisle, being a doctor, might tend to her wounds. This could lead to an intimate moment of care and concern between them, deepening their connection that might be different from the typical Bella - Edward relationship in the original 'Twilight' series.
Sure. In some fanfictions, Bella is shown as an expert vampire hunter. She uses her knowledge of vampires' weaknesses and her own agility to take on multiple vampires at once. It's a complete departure from her more vulnerable self in the original story.
Maybe she spreads a false rumor about someone in the fanfiction. This causes a big uproar in the school or community she's in. As a result, the person she spread the rumor about confronts her, and she has to deal with the anger and disappointment of those around her who thought better of her.
Often, it starts with an unexpected encounter or a moment of realization. Maybe Carlisle sees Bella in a new light, not just as Edward's girlfriend but as an individual with her own charm. Then, there are small gestures of kindness and understanding between them that gradually build up the relationship.
Pooh could get stuck in a net set up by some mischievous characters in the fanfiction. They were trying to catch something else, but Pooh accidentally wandered into it. His friends would then have to come up with a clever plan to free him. They might try to chew through the net or find the ones who set the net and ask them to let Pooh go. In yet another case, Pooh could get stuck in a strong wind current that blows him into a corner and holds him there. He would have to wait for the wind to die down or figure out how to move against it.
In some fanfictions, their relationship might start with Carlisle being drawn to Bella's unique spirit. He, as an older and more experienced vampire, is intrigued by her resilience. Maybe he first notices her when she enters the Cullen family's orbit, and from there, a slow - burning attraction begins to form as they interact more and get to know each other on a deeper level.
