Fanfiction about Morgan's sister in Criminal Minds: What are some possible storylines?

One possible storyline could be that Morgan's sister gets involved in one of the BAU cases indirectly. Maybe she has a connection to a victim or a suspect through her work or personal life. For example, if she is a teacher and one of her students is related to a case. Another could be that she decides to follow in Morgan's footsteps and starts training in criminal psychology, which creates a whole new dynamic between them. There could also be a storyline where she is in danger and Morgan has to use all his skills and resources to protect her, leading to some intense emotional moments between the two.

She could be a journalist who is investigating a story that intersects with the BAU's work. This would put her in a position where she has some information that the team needs, but she also has her own motives and deadlines. There could be a conflict between Morgan wanting to protect her and her determination to get the story. Also, she might form a friendship with one of the other team members, like Garcia, and through that relationship, she gets more involved in the BAU world. And she could end up using her journalistic skills to help the team in unexpected ways, like uncovering a hidden connection between cases.

A storyline might involve Morgan's sister coming to visit him at the BAU. While there, she starts to notice some strange behavior from one of the team members. This could lead to her helping the team solve an internal mystery. Or perhaps she has a special talent, like being extremely observant, which she uses to assist the BAU in a case without really meaning to at first. It could also be that she has a past trauma that resurfaces when she gets involved in a case - like a kidnapping that happened near her when she was younger - and this affects how she interacts with the case and the team.
