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.
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.
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.
The main characters are Tony and Ziva, of course. Tony is often portrayed as the charming and sometimes goofy agent, while Ziva is the strong - willed and mysterious one. Their personalities contrast and complement each other in the fanfiction, which makes their secret relationship all the more interesting.
If Ziva is pregnant in fanfiction, their relationship could become more intimate. They would have to rely on each other more. Tony might become more protective of Ziva.
It could develop slowly. They might start as friends again, carefully testing the waters. Tony could be hesitant because of past hurts, and Ziva might be guarded as well. But as they spend more time together, they gradually become closer.
Well, it might start with a bit of mutual distrust. Tony might think Ziva is too serious and Ziva might think Tony is too flippant. But as they work together on cases, they start to see the good in each other. For example, Tony realizes Ziva's loyalty and Ziva sees Tony's intelligence in solving cases.
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.
