Her friends would likely be very shocked and worried. Some might rush to the hospital immediately and stay by her side, constantly checking on her condition. For example, her best friend might be in tears and refuse to leave until they know Bella is out of danger.
Edward would be extremely distraught. He might blame himself for not being there to protect Bella. He would likely stay by her side constantly, using his vampire abilities to try and heal her if possible. Alice, on the other hand, might have seen the accident coming in one of her visions but was unable to prevent it. She would be filled with guilt and would try to use her visions to figure out how to help Bella recover.
Fishlegs would be really concerned and would use his knowledge to try and help. He might look for herbs or remedies that could aid in Hiccup's recovery. Snotlout, on the other hand, might initially try to act tough but deep down he'd be just as worried. He might try to show off his strength by helping to carry Hiccup or something like that. And Tuffnut and Ruffnut would be their usual chaotic selves, but also very caring towards Hiccup in their own unique way. They could make jokes to try and cheer him up while he's in pain.
Her parents would be extremely worried. They might rush to the hospital and stay by her side constantly, crying and praying for her recovery.
Sebastian, being the efficient butler, would likely immediately take charge of the situation. He would ensure the girl gets proper medical attention if possible. He might also start investigating the circumstances around the accident, suspecting foul play as is often the case in the 'Black Butler' world.
Olaf would try to make Anna laugh. He would tell his silly jokes and do his goofy dances. He would also try to keep Anna warm with his carrot nose. He might even build a small snowman inside the room to keep Anna company when everyone else is busy.
Well, initially, her friends would be stunned. Harry would be at a loss for words. He'd be thinking about all the times they had together and how Hermione's appearance was part of who she was. Ron would probably blurt out something insensitive in his shock. But as time passed, Harry would start to see that Hermione was still the same person inside. Ron would slowly come around too, especially when he realized that Hermione's decision was more complex than he first thought. Ginny would be the one to really help Hermione feel accepted, reminding her that her true self was more important than her new look.
Some of her more practical friends might start looking into the cause of the accident. They could be the ones to find out if there was any foul play involved. Meanwhile, her more emotional friends might be the ones crying and praying for her recovery.
Dean would probably be extremely confused at first. He might stand there, staring at his car with a bewildered look on his face, muttering things like 'This can't be real'.
Yang would be very emotional. She'd be heartbroken that Ruby doesn't remember their shared experiences. She might try to recreate memories, like taking Ruby to their favorite childhood places. Weiss would take on a more practical approach. She'd research any possible cures for amnesia in the RWBY world, whether it's through dust or some other means. Blake would be the quiet support. She'd stay by Ruby's side, listening to her when she's confused and gently guiding her through the things she doesn't understand.
Sakura, being the kind - hearted and practical one, would immediately start giving Naruto advice on how to keep his braces clean. She might also tell him about the foods he should avoid so that the braces don't get damaged. Sasuke, on the other hand, would be his usual aloof self. However, if any other village kids were to make fun of Naruto because of the braces, Sasuke might subtly step in and intimidate them. Shikamaru would likely grumble about Naruto's new look adding to the chaos in their group. But deep down, he would understand that it's just another thing that makes Naruto unique. Kiba and Akamaru would initially find it funny. Kiba might even joke that Naruto's braces look like some strange ninja weapon. But as time goes on, they would all get used to it and it would just become a normal part of Naruto.
