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.
Abby's character could develop by becoming more protective of McGee. In the fanfiction, she might start to see threats to their relationship everywhere and become a bit overprotective. This could lead to some interesting conflicts. McGee, on the other hand, could grow into a more nurturing role. He might start to take care of Abby in ways he didn't before, like making sure she eats well and gets enough rest. And together, they could develop a stronger sense of teamwork in their relationship, just like they do at work, but now in the context of their marriage.
Their relationship would likely become more intimate and protective. If Abby is pregnant, McGee would be constantly looking out for her, making sure she's not overworking or getting into dangerous situations at work.
There could be many scenarios in such a fanfiction. Maybe it happens during a high - stress case when they finally realize their feelings for each other. For example, after they solve a really tough mystery together and the relief and joy make them share a spontaneous kiss.
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.
A fellow scientist named Tom, perhaps. He could be a bit of a joker but also very brilliant. He and Abby might have a friendly rivalry, constantly trying to outdo each other in their experiments, but also respecting each other's skills. And then there could be the lab technician, Lisa. She is the one who keeps all the equipment in working order. Without her, Abby's experiments would be constantly interrupted by faulty machinery. She's a bit quiet but very reliable.
It could also lead to some complications. For instance, if there are any rules in the NCIS about relationships between colleagues. They might have to face some disciplinary actions or at least some serious discussions with their superiors. But in the end, their love could overcome these obstacles as they fight for their relationship together.
Their relationship would likely become more intimate on an emotional level. Gibbs would probably be more open and tender towards Abby, seeing her in a new light as a mother - to - be.
One possible plot could be that Abby discovers she's pregnant. McGee would be over the moon but also a bit nervous. They might face challenges at work as they try to balance their jobs at NCIS with the upcoming new addition to their family. Their colleagues could be supportive, but there might also be some concerns about Abby's safety in the field.
She might become more empathetic. Pregnancy can bring out different emotions, and Abby could start to understand others' situations better. For example, she might be more patient with victims in cases.
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.
For Kensi, her character could develop in the sense that she discovers a new side of herself. She's always been tough, but now she has this new life growing inside her. This could make her more empathetic towards victims who are mothers or pregnant women. Callen would likely develop into a more family - oriented man. He might start thinking about settling down more seriously. He could also become more open with his emotions, especially when it comes to Kensi and the baby. They both would grow in their ability to rely on each other in different ways than just as partners in crime - fighting.
