In some fanfictions, Leon and Ada's relationship is often filled with mystery and tension. Since Ada is a complex character, her interactions with Leon can range from being somewhat antagonistic to having a deep, unspoken connection. When it comes to a 'baby' in the fanfiction, it could be used as a plot device to either bring them closer or create more conflict. For example, if they were protecting the baby together, it would force them to work in unison and perhaps explore their feelings more openly.
One common theme is the struggle between love and duty. Leon and Ada are often on different sides in the official stories, so fanfics explore how their feelings for each other play out against their respective missions. For example, in many fanfics, Ada has to make a choice between helping Leon and fulfilling her own tasks.
One common theme is trust. Since they often find themselves in precarious situations, the question of whether they can trust each other fully is a big part. For example, in many fanfics, Leon has to decide if he can trust Ada's motives.
One possible plotline could be Ada and Leon teaming up against a new bio - terrorist threat. They might start off distrusting each other as in their previous encounters, but gradually learn to rely on one another.
