Stiles might initially be shocked. He has been a part of the pack for a long time, and Scott kicking him out would be completely unexpected. He could stand there in disbelief, unable to process what has just happened.
One possible reason could be a misunderstanding. Maybe Stiles did something that Scott misinterpreted as a betrayal of the pack. For example, if Stiles made a deal with an enemy without Scott's knowledge, even if it was to protect the pack in the long run, Scott might see it as a breach of trust and decide to kick him out.
One reason could be a misunderstanding. Maybe someone in the pack misinterprets Stiles' actions as being against the pack's interests. For example, if he's involved in something that looks like it's endangering the pack but in reality he's trying to protect it.
It becomes strained. Trust is broken, and Stiles may start to distance himself from Scott. He might not believe in Scott's words or actions anymore, and there will be a lot of tension between them.
One common plotline could be the pack learning to better support Stiles. For example, they might adjust their communication methods to be more clear for someone with ADHD. They could start using visual aids or more direct language. Another plotline might involve Stiles struggling to keep up with pack activities at first due to his ADHD symptoms like inattention or impulsivity, but then gradually finding his own ways to contribute. Maybe he uses his hyperfocus on things like research for the pack's benefit.
Perhaps he feels that the other pack can offer him more opportunities for growth. In some fanfictions, the new pack might have access to different kinds of magic or knowledge that Stiles is eager to learn. So, he joins them to expand his skills and understanding.
One way is for the pack members to stand up for Stiles more often. If someone outside the pack is giving him a hard time, they should be there to protect him. Also, they could share their secrets with him, which would show that they trust him. This trust is an important part of any relationship and would help Stiles realize that they don't actually hate him.
His father could be one of the supporters. His father has always been there for Stiles, and he would understand if Stiles was standing up for what's right within the pack. Another possibility is Lydia. She's a smart and powerful character herself, and she might see the value in Stiles' actions and support him.
There could be. However, the popularity of such fanfiction might vary. It really depends on how the author portrays the 'pack is possessive of stiles' concept. Some might write it in a way that's really engaging, while others might not do it so well. You may have to search through different tags and authors to find the really good ones.
