I'm not sure specifically as there could be many different takes on this in fanfiction. It might involve the pack's reaction to Stiles' scars, perhaps leading to a deeper understanding of his past traumas or adventures that caused the scars.
Yes, perhaps the scars are not what they seem at first glance. They could be some kind of marking from an ancient power that is now awakening, which would be a huge plot twist and change the whole dynamic of the story.
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.
Well, it could be about the pack in a particular fictional universe having strong feelings of love or deep affection for the character named Stiles. It might explore their relationships, how they support Stiles, and the unique bond they share. Maybe it shows different scenarios where the pack's love for Stiles is put to the test or becomes a central theme in various adventures or emotional situations.
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.
Scott would be the most likely one. He's Stiles' best friend and the True Alpha. He would never let the Alpha pack harm Stiles and would go to great lengths to rescue him.
