A great plot could be that the OC is a hacker who gets involved with the BAU because they unknowingly hacked into some information related to a serial killer. Morgan is assigned to keep an eye on the OC. As they work together, they start to respect each other's abilities. The OC could also have a personal vendetta against the killer which adds an extra layer of drama. They could also develop a romantic relationship as they solve the case.
A believable OC needs to have real - world experiences that shape who they are. In the context of Criminal Minds, if the OC is supposed to be a part of the action, they could have had a family member who was a victim of a crime in the past. This would fuel their drive to be involved in solving cases. Their skills should also be developed over time. Don't make them a super - human who can do everything perfectly. Let them struggle and learn, especially when working with Morgan who has a lot of experience.
Fanfiction.net could also be a great source. It has a large collection of fanfictions. You might need to sift through a bit more compared to AO3 as the tagging system isn't as refined. But if you search for 'Criminal Minds' and then look for stories specifically about Morgan getting hurt within the search results, you can find some interesting ones.
One popular theme is teamwork. Fanfics often focus on how Spencer and Morgan work together seamlessly to solve cases. Their different skillsets - Spencer's academic knowledge and Morgan's practical experience - combine to crack the toughest of cases.
A moment that stands out in some fanfictions is when they support each other through personal crises. Like when Garcia has a family issue and Morgan is there for her, or when Morgan is struggling with something from his past and Garcia offers her unwavering friendship. It shows the strength of their bond.
One great fanfiction could be where Morgan and Garcia go on an undercover mission together. They have to pretend to be a couple, which leads to some really cute and comical moments as they struggle to keep their professional relationship intact while playing the part. It might also explore the underlying feelings they've always had for each other.
Well, a great fanfiction storyline could involve Reid and Morgan going undercover together. Maybe they have to infiltrate a criminal organization. Reid could use his knowledge of psychology to manipulate the criminals from the inside, while Morgan uses his combat skills to keep them safe. It could also be a story where they are dealing with the aftermath of a traumatic case that has affected them both in different ways, and they help each other heal.
One common theme is the emotional impact on the team. When Morgan gets hurt, it often shakes up the whole BAU crew. They might show their concern, worry, and support in different ways. Another theme could be Morgan's own struggle to recover, both physically and mentally. He's a strong character, but getting hurt challenges that strength.
The relationship in the fanfic could also show a mentorship aspect. Morgan, being more experienced in the field, might guide Spencer not only in the work - related matters but also in dealing with the emotional toll of the job. For example, in some fanfics, Morgan helps Spencer understand how to handle the stress of seeing the dark side of humanity on a daily basis.
The best interactions often involve them teasing each other. For example, Morgan might tease Reid about his lack of social skills in a light - hearted way, and Reid would come back with some smart - aleck comment about Morgan's taste in music or something. Another great interaction is when they support each other during tough cases. Morgan might give Reid a pep talk when he's doubting himself, and Reid would offer his brilliant insights to help Morgan see things from a different perspective.
