The other members of the Glee Club like Kurt, Mercedes, and Santana would most likely be involved. They are Rachel's friends and would be there to support her, offer their opinions, and be part of the whole journey of her pregnancy, whether it's through helping her with doctor's appointments or just being there for emotional support.
Finn could be involved if the fanfiction wants to explore a relationship with him as the possible father. He was an important part of Rachel's life in the original series, and his reaction to the news would be significant.
Finn is very likely to be involved. If he's the father, he would have a huge role in the story. He'd need to deal with his own feelings about becoming a father so young and how it affects his football and Glee club activities. Quinn could also be involved. She might offer Rachel advice based on her own experience with pregnancy, even though their situations were different. And of course, Mr. Schuester would be there. He'd be like a mentor to Rachel, guiding her through the tough times and making sure she still has a place in the Glee club.
Mr. Schuester might be included as well. As the teacher and mentor in the Glee club, he could offer guidance to Rachel during this difficult time. He might help her figure out how to balance school, the Glee club, and her pregnancy. Additionally, Mercedes could be a character involved, providing her best - friend - like support to Rachel, and being there for her through all the emotional ups and downs.
Finn could be involved. Maybe he got into a huge fight with Rachel over something, like her career choices affecting their relationship, and in the heat of the moment, someone filed a restraining order on her behalf. Quinn might also be involved. If she still had some unresolved jealousy or issues with Rachel, she could be the one who instigated the restraining order, either directly or by influencing others.
It's possible that Rachel and Will are characters from a less - known or niche media. They could be part of a small - scale web series or a local theater production that has a dedicated fan base. In the fanfiction, the writer may be expanding on the hinted - at relationship between them from the original source material and taking it in the direction of pregnancy, exploring how that would change their lives, their relationships with other characters, and their own personal growth.
It could be an overzealous security guard. If Rachel was at a high - profile event and the security guard misinterpreted her actions as something threatening or against the rules, he could be the one to call the cops and get her arrested.
I think Quinn could be a great addition. She could be the one who initially misunderstands the situation between Sam and Rachel and causes some drama. Also, Finn could be included as he might have his own feelings about Rachel being with Sam.
Well, obviously Rachel Berry and Sunshine. But also, other members of the glee club could be involved. For instance, Finn might try to defend Rachel, thinking she's innocent. Or Santana could be there, making sarcastic comments about the whole situation. Kurt might also be involved, perhaps using his connections to try and get Rachel out of jail. And of course, the adults in the story like Mr. Schuester could play a role. He might be shocked at first but then start to investigate to prove Rachel's innocence.
It could also be Jesse St. James. Given their past history and the complex relationship they've had, it's possible that in a fanfic he could be the father. Maybe they had a brief encounter that led to the pregnancy.
One possible plotline could be Rachel dealing with the reactions of her friends and family. They might be shocked at first but then come around to support her. For example, her friends could throw her a baby shower, which would be a really heartwarming part of the story.
At this point, it's hard to say for sure. But considering the 'Life Is Strange' series, we might see Chloe as she has a significant connection to Rachel.
