In the fanfic, perhaps they discover a hidden part of the backstage area together. They start exploring and find an old prop that has some sort of significance to the history of the theater. This discovery could lead to a deeper bond between them as they share their thoughts about the theater's past.
They could start by sharing their dreams and aspirations about their acting careers. This would help them understand each other on a deeper level. For instance, if Vanessa wants to perform on Broadway one day and Beckett has some experience there, he could give her valuable advice.
In such a fanfic, they could be there for a business meeting. Maybe they meet by chance in the hotel lobby and end up collaborating on a project. Beckett might be a bit reserved at first, but Josh's friendly nature breaks the ice.
Well, they might share some deep secrets. Maybe Beckett has some important information to tell Josh, or they could be planning something together in secret.
Another thing that could occur is that Castle decides to confront Beckett about what he saw. He could be really straightforward and ask her what's going on between her and Vaughn. This could lead to an argument or a really honest conversation about their relationship.
One possibility is that Castle has booked the hotel for a romantic getaway by himself, and seeing Beckett there completely throws him off. Beckett could be there for a much more serious reason, like following a lead on a dangerous criminal. Castle may start to worry about Beckett's safety and decides to stay close to her. As they interact more within the hotel, they might realize how much they've missed each other's company, and this chance meeting could be the start of something new between them, whether it's a new level of friendship or a re - awakening of their romantic feelings.
In a fanfic like this, there could be a lot of emotional turmoil. Beckett and Castle might start to realize how much they actually rely on each other. When they are pretending to be separated, they could find that they miss the little things about each other. For instance, Castle might miss how Beckett always has a smart comeback during their banter, and Beckett might miss Castle's goofy sense of humor. This could lead to some internal conflict for them as they try to maintain the facade while also dealing with their growing feelings for each other during this 'pretend' separation.
In this fanfiction, the baby boy could be the center of a family drama. Maybe Castle's ex - wife shows up, claiming she has some rights to the baby. This causes a rift between Castle and Beckett as they deal with the legal and emotional turmoil. However, in the end, they come together stronger than ever, with their baby boy being the glue that holds their family together.
There could be a moral dilemma in the story. What if the kidnapper demands something unethical in exchange for the child?

But in the end, they would find a way to outsmart the kidnapper and get their child back safely.
Well, perhaps Rose and Vanessa could be going on an adventure with their dad. Maybe they're going fishing and their dad is teaching them how to bait the hook. It could be a really cute family - oriented story where they bond over simple activities like that.

They start as friends, sharing their love for art and literature, and gradually fall in love. Beckett decides to remarry because this new person makes him feel alive and understood in a way he hasn't felt before.
