Princess Bella is obviously a very important character as she is the one going into labor. Her partner or husband would also be important as he would likely be there for support.
We might expect a lot of drama and emotion. There could be a focus on the support system around Princess Bella, like her family and friends. Maybe there are midwives or healers helping her through the process.
Obviously, Bella is one of the main characters. There might also be the teachers or students at Sky High like Will Stronghold or Layla Williams.
In the fanfiction, it's very possible that Puck would be at Quinn's side during labor. He has a history with her and would surely care about her well - being. Her best friends from Glee club would also be around. Rachel, with her big heart, would probably be there offering words of encouragement. Finn, being a good friend, would also show up. And Santana, who has a strong bond with Quinn, would be there to give her strength and sass when needed.
Obviously, Edward would be deeply impacted. He has dedicated himself to Bella, and her new evil nature would force him to reevaluate their relationship. Jacob, who has always been in the mix with Bella, would face a great deal of turmoil. And don't forget Carlisle and the rest of the Cullen family. They have accepted Bella into their family, and her going evil would be a major threat to their way of life and their values.
The caretaker of the orphanage could be an important character. They could be either very strict and cold, creating a difficult environment for Bella, or they could be warm - hearted and act as a parental figure to her.

David is surely an important character as the story is about him going to school.
Bella could meet an old neighbor. This neighbor might tell her about the changes in the neighborhood over the years.

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.
