There might be a fanfic titled 'Goodbye, NCIS: McGee's Farewell' which focuses on McGee leaving NCIS due to a family emergency. It shows how he struggles to adjust to a life away from the agency he's been a part of for so long, and how his friends support him during this tough time.
In some interpretations, it could create a big void. McGee has been an important part of the team for a long time. His departure might mean that the team has to scramble to fill his technological expertise. For example, they might have to bring in a new, inexperienced character who has to learn on the job, which would change the team dynamics.
Abby's character might become more domesticated. She's always been a bit of a free spirit, but being married could make her more settled. She might start to focus more on building a home and a family life. For McGee, he could become more confident in his personal life. He's often been a bit shy and reserved, but with Abby by his side as his wife, he might find himself being more assertive in social situations. Also, they could both develop more patience with each other as they face the daily challenges of married life.
The theme of self - discovery can also be present. When Tony is hurt, he might have time to reflect on his life, his relationships, and his career in NCIS. For instance, he could think about his past actions and how he can improve. And sometimes, there are themes related to his relationships with his colleagues getting deeper as they take care of him during his recovery.
A plot twist might be that Abby discovers she's pregnant before the wedding, but she's not sure if McGee is ready for fatherhood. This could create a rift between them as they struggle to communicate their feelings. Or, it could turn out that someone has been secretly trying to break them up all along, and at the last minute, they reveal all the lies and misunderstandings they've been spreading. Also, there could be a situation where McGee has an accident and loses his memory, forgetting about the wedding and his relationship with Abby, leading to a heart - wrenching journey of her trying to make him remember.
