She might meet her younger self. It would be an odd yet fascinating encounter, as she could see how she used to be and compare it to who she is now.
Bella could meet an old neighbor. This neighbor might tell her about the changes in the neighborhood over the years. Maybe there are new families, new stores, or even some interesting local events that she has missed. It would be a great way to bring a sense of familiarity and newness to the story at the same time.
Bella might meet her former teachers in Phoenix. These teachers could have a different view of her now that she has been through so much in Forks. They might offer her some words of wisdom or advice that could influence her decisions regarding her future. Also, she could meet some family friends who were part of her life before she moved to Forks. Meeting them could bring back a flood of memories and emotions, and they could play a role in her self - discovery process as she tries to figure out her place in both the Phoenix and Forks worlds.
Bella could meet a street-smart local who shows her all the cool, off - the - beaten - path places in New York. This person could teach her how to navigate the subway system and where to find the best street food.
Maybe Bella will have some amazing adventures with Peter in the past. She could witness historical events together with him, or they might fall in love in that different time period.
She might meet her past self. This could lead to some really interesting conversations and self - discovery. Maybe she'll learn things about her past that she had forgotten or overlooked.
I think the most exciting part would be when Bella and Peter start to influence the past in some way. Maybe they accidentally change a small event, and then they have to figure out how to fix it or deal with the consequences. It adds a lot of drama and tension to the story.
Edward would definitely interact differently. If Bella goes back in time and changes her initial approach, Edward might be more or less intrigued by her. For example, if she's more confident, he might be even more drawn to her than in the original story.
There is also a possibility that a lone vampire, who has a sense of justice or who has been secretly observing Bella and has grown fond of her, decides to take on the Volturi and rescue her. This vampire could have some special abilities or knowledge that gives them an edge against the powerful Volturi.
Well, aside from the obvious ones like Alucard, Integra, and Seras, Bella might also interact with Walter. Walter is an old and experienced member of the Hellsing staff. He could be a mentor figure to Bella, teaching her about the history and secrets of the Hellsing Organization. Another character could be the Major from the Millennium Organization. If there's a crossover or a story where the two organizations clash, Bella would surely cross paths with him. His crazy and unpredictable nature would make for some interesting interactions with Bella.
Her father, Charlie, might try to rescue her. He loves Bella deeply and would be very worried when she goes missing. He could start investigating and find out that the Cullens are involved.
