Well, one possible plot development could be that Seth's imprinting acts as a catalyst for the girl's healing process. He might use his supernatural abilities and his unwavering loyalty (which comes with imprinting) to protect her from further harm. For example, he could stand up to her abusers, whether they are human or from the supernatural world if it's in that kind of fanfiction setting. This would start to build trust between them, and as she begins to heal, their relationship could grow deeper, perhaps leading to a romantic relationship down the line.
A major theme is growth. Both Paul and Seth grow as individuals and as a pair. They learn about themselves and each other. Also, the theme of loyalty often comes up. Their loyalty to each other and to the pack has to be re - evaluated and adjusted because of the imprint. For example, in some fanfics, they have to prove their loyalty to the pack while still maintaining their new bond.
One common theme is the idea of an unbreakable bond. Since imprinting is such a strong concept in the Twilight world, fanfictions often explore how this bond between Seth and Bella is unshakable, no matter what challenges they face.
One great fanfiction could be 'Seth's Unwavering Bond' where it delves deep into how Seth's imprint on Bella changes his life. It shows his growth from a young werewolf to someone with a newfound purpose because of the imprint.
One popular Seth imprints on Bella fanfiction is 'Seth's Imprint'. It explores the unique relationship that forms between them in a really sweet way. The story focuses on how Seth's imprint on Bella changes the dynamics within the werewolf pack and also in Bella's life.
The other characters in the pack might initially be very protective of Seth. They could be worried that the girl's past abuse might make her unpredictable or a liability. For example, they might be cautious about sharing pack secrets with her at first. However, if Seth is able to show them that she's trustworthy and on the path to healing, they might start to accept her more. On the other hand, there could be antagonists in the story who see Seth's connection to the girl as a weakness and try to use it against him.
