Perhaps Frisk, being hurt, will initially be distrustful of Dream when they meet. But as they interact, Frisk realizes that Dream is sincere in his offer to help. Dream could then share some of his wisdom or knowledge about the world they are in. This knowledge might be crucial for Frisk's survival or for achieving their goals in the story. He could tell Frisk about hidden paths or dangerous foes that lie ahead.
Well, one possibility is that Dream could use his positive energy to heal Frisk. Since Dream is often depicted as a benevolent character, he might sense Frisk's pain and offer some sort of magical assistance. Maybe he has special powers that can soothe Frisk's wounds and give them the strength to continue on their journey.
Well, perhaps the Autobots would immediately come to the reader's aid. They might use their advanced technology to heal the reader's injuries. For example, Ratchet could use his medical tools to fix any broken bones or serious wounds. Then, they could take the reader back to their base for further protection and to figure out why the reader was hurt in the first place.
The meeting could change the story in a major way. If Frisk was on a dangerous quest before being hurt and meeting Dream, Dream could provide the necessary support to turn the tides. For example, he might give Frisk a magic item that makes them more powerful or protected.
Well, Frisk could be cautious at first. Since Chara in Underswap is different, Frisk might be on guard. However, as they get to know each other, they could become friends. For example, they might share stories about their friends in their respective worlds. Frisk could talk about Sans and Papyrus, while Underswap Chara could talk about their own versions of the characters. Eventually, they could team up to face some challenges in the Underswap world.
Perhaps the doctor uses BTS as a form of distraction for the hurt Army reader. He or she might play BTS music in the treatment room or talk about the group's latest comeback. This could make the whole experience of getting treated less painful and more enjoyable for the reader. And who knows, the Army might end up getting special treatment just because of their shared love for BTS.
Well, one possibility is that there would be a lot of confusion. Frisk, being the kind-hearted protagonist, might try to reason with Error. Chara, on the other hand, could be more unpredictable. Error might see them as glitches in the fabric of his world - or whatever strange view he has. Maybe he'd try to destroy them at first, but Frisk's determination could change his mind.
Well, perhaps the next generation could be shocked by the Dursleys' cold and unfriendly nature. They might try to change the Dursleys' views on magic.
Well, he could go on an adventure with the elf. Maybe they'll explore some hidden parts of the magical world together, like a secret forest filled with ancient magic. Or perhaps the elf will introduce Harry to other magical creatures that he's never met before.
Kiba might immediately take Naruto to the nearest medical ninja. In the Hidden Leaf Village, there are always medical ninjas on standby. Kiba's quick action could save Naruto from a more serious condition.
Sodapop could also try to tend to Ponyboy's injuries himself if they seem minor at first. He'd probably be full of worry and keep asking Ponyboy what happened. Maybe it was a fight with the Socs or an accident. Sodapop would be desperate to make sure Ponyboy is okay, and his protective instincts would kick in big time.
The first thing that could happen is that his friends would immediately start to tend to his wounds. Erza, being the strong and reliable one, might take charge of the situation. She could use her medical knowledge, if she has any in the fanfiction world, or she could call for help from a more experienced healer. This would show the bond between Natsu and his friends.
