Jemma Simmons, the school's nurse and a student at Avengers Highschool, she's an inhuman, her inhuman ability is to heal any wound, but only the nice the nice ones thank her and give her thank you gifts, which is basically every single kid in the school except for 4 students, Daisy Johnson, Lincoln, Robbie Reyes, Gabriel Reyes.
Jemma has a crush on Daisy, but Daisy and her friends and her boyfriend, Lincoln, are assholes to her.
They spread a lie around the school that Jemma had slept with most of the boys at the school, and even slept with a few teachers, too, all four of them make her life a living hell everyday.
Daisy's inhuman ability is quake, she basically can control an earthquake, Lincoln's inhuman ability is electricity, Robbie isn't an inhuman, he made a deal with the devil, to protect his younger brother and to punish all that sin, Gabriel, Robbie's younger brother, isn't an inhuman either, he's just stuck in a wheelchair from a dangerous accident that made Robbie deal with the devil.
But when all five of them end up in detention after a mistake that Lincoln did, things start to turn into a total clusterfuck.
And the only other two people who doesn't treat her like shit are her brothers, Leapold Fitz and Deke, they don't have any inhuman ability's, but they're all really super duper smart.
This is a Skimmons inhuman highschool au. I don't any of these characters, go watch Agents of S.H.E.I.L.D. on Netflix if you have it, it's a great show.
