In the fanfiction, Summer might get hurt during a competition. Let's say she clashes with another band member from the rival group and gets pushed. This would create a tense situation. The School of Rock kids would be outraged and demand justice. But Summer, being the strong - willed character she is, tells them to focus on the music. She then uses her time to recover by learning new musical techniques and when she returns, she surprises everyone with her improved skills.
Perhaps Summer gets hurt in a rehearsal accident. For example, some equipment malfunctions and she gets a minor injury. This could lead to a story where the kids in the School of Rock learn about safety measures in a more serious way. They might have to postpone their shows and face the disappointment of their fans. Meanwhile, Summer could be feeling frustrated and left out, but her friends visit her often and they come up with creative ways to keep her involved, like having her write new lyrics from her hospital bed.
The other characters would be very concerned. Dewey, the teacher, would probably immediately rush to her side and make sure she gets proper medical attention. Zack might be in shock at first, but then he would step up and try to take on some of Summer's responsibilities in the band, like leading the rehearsals. Freddy would be constantly checking on her, bringing her little gifts to cheer her up. And Tomika would be the one to comfort Summer emotionally, listening to her fears and frustrations about getting hurt and being unable to perform for a while.
Another plot could be that Summer faces some kind of personal attack outside of the band that makes her question her place in the School of Rock world. For example, she might be bullied by other music students. The fanfiction could detail how she copes with this hurt, and how her friends in the band support her and help her regain her confidence.
It could be that Summer is kidnapped by a group of thieves who mistake her for someone else. They think she has a valuable music manuscript that's actually in the possession of another person. While kidnapped, Summer tries to convince them of their mistake. The School of Rock crew figures out she's been taken and teams up with the police. They use their knowledge of the music scene and the places Summer likes to go to help the police find her.
It could be a rival music group. They might be jealous of the success of Summer's band and try to undermine them. For instance, they could spread false rumors about Summer which cause her emotional pain.
One possible plot could be that Freddy has had a long - hidden crush on Summer. He finally gets the courage to kiss her after a big performance by the school of rock band. This kiss could be the start of a sweet and innocent relationship, where they discover their shared love for music in new ways and support each other through the challenges of school and the band.
One possible plot could be that Christy gets hurt during a sports event. Maybe she's playing soccer and gets tackled too hard. Her friends then rush to her side, and the story could focus on their reactions and how they help her. For example, one friend might call an ambulance while another stays with her to keep her calm.
One possible plot could be that Mulan gets hurt on her way back home after the war. She might encounter bandits and get injured while defending herself. This would delay her return home and add more challenges to her journey, like finding shelter and treatment in an unfriendly area.
Perhaps she gets hurt while exploring an old, haunted place. She might trip and injure herself while running away from a spooky apparition. Her injury then becomes a hindrance in her further exploration and she has to rely on others for help, which could change the dynamics of her relationships in the fanfiction.
One possibility could be that Garcia gets hurt during a case. Maybe she's on a mission to hack into a dangerous criminal's system and they trace her location, leading to an attack. Her friends in the BAU then go on a hunt to find the culprits while also trying to save her.
Maybe Judy gets physically injured during a dangerous adventure. For example, she could be exploring an old, abandoned building and accidentally fall through a rotten floorboard.
