Another plotline might involve them having to go undercover as a married couple. During this time, they have to act like a loving couple in public, which forces them to confront their real feelings for each other. They start to realize that the pretend relationship is starting to feel very real, and they finally admit their love.
A third plotline could be set in a post - NCIS world. Tony and Ziva have both left the agency and are trying to build a normal life. They meet by chance in a small town. At first, they are hesitant to re - engage, but as they spend more time together, they remember why they were attracted to each other in the first place and their romance blossoms anew.
One interesting plotline could be their reunion after a long separation. Maybe Ziva has been on a dangerous mission and was presumed dead, but she returns. Tony has to deal with his mixed emotions of anger for her leaving and overwhelming joy at her return. They then slowly rekindle their romance.
Another plotline could be that after Ziva leaves NCIS, Tony realizes how much he misses her. He then sets out on a journey to find her and when he does, they have a heart - to - heart conversation that rekindles their old flame. They then have to figure out how to make their relationship work with all the complications of their past and their different lives.
One interesting plotline could be their adjustment to married life while still being involved in their dangerous line of work. They might face challenges like keeping their relationship a secret from enemies. Another could be their decision to start a family and how they balance that with their jobs.
A possible plotline could also be that they have a near - discovery moment. For example, someone on the team almost stumbles upon a clue that they are in a relationship, like finding a special gift Tony gave Ziva. This would create a lot of suspense as they try to cover it up and keep their secret safe.
Perhaps the kiss is the start of a relationship that faces many challenges. For example, Ziva's past and her family's expectations might come into play. Tony, on the other hand, has his own insecurities. Their relationship could be a roller - coaster of emotions as they try to navigate through these issues together.
One idea could be that their daughter discovers she has a special talent for solving mysteries, just like her parents. She might start by helping solve a small mystery in her school or neighborhood, using the skills she's learned from Tony and Ziva's stories. Another plot could involve her trying to find out more about her parents' past adventures, which leads her on an exciting journey of her own. Maybe she uncovers a long - lost secret related to a case they worked on together.
One plot idea could be that Ziva and Tony are undercover as a married couple at a high - society event. They have to blend in and gather intel on a criminal who is using the event to launder money. Another could be that they are undercover in a dangerous cult to rescue a kidnapped agent, and during their time there, they start to realize new things about each other. A third idea is that they go undercover as rival spies in an international arms deal, but their fake rivalry starts to turn into something more real and they have to deal with their feelings while still completing the mission.
In some NCIS fanfiction, Ziva could be pregnant. Fanfiction often explores different scenarios for beloved characters. Writers might create a story where Ziva's pregnancy brings new challenges and developments to her relationship with Tony. It could be a plot device to explore deeper emotions and create more complex storylines within the NCIS universe.
Gibbs would be a great character to include. He could be the one who notices the growing relationship between Ziva and Tony before they even realize it themselves. He might give them some sage advice or just be there as a sort of father figure guiding them through the early stages of their relationship.
One possibility could be that it would completely change their dynamic at work. They might become more protective of each other and start to think about their future outside of NCIS. For example, Tony might become more serious and start thinking about settling down in a more permanent way. Ziva, on the other hand, might struggle with how being pregnant would affect her role as an agent.
One plot idea could be that Tony and Ziva are trying to raise their baby while still being involved in NCIS cases. They might have to deal with danger that comes too close to their family. Another could be the baby having some sort of special ability that they need to protect from bad guys who find out about it. Maybe the baby's birth also brings some old enemies of Tony or Ziva back into their lives, creating a whole new set of challenges for them.
