Their relationship could develop in many ways. For example, they could team up more often as allies against a greater threat in Gotham. This would strengthen their bond as they learn to trust each other more. Or, Selina could fully embrace the side of good and join Bruce in his fight for justice, becoming a more permanent part of his life.
In Bruce and Selina's fanfiction, the 'soulmate' trope is quite prevalent. Despite their differences, they seem to understand each other on a deeper level that others can't. There's also the 'protective love' trope. Bruce, as Batman, will always want to protect Selina, even from herself sometimes. And the 'tug - of - war' between their two worlds. Bruce's world of law and order and Selina's world of chaos and freedom is constantly in play, and this struggle is a key part of their relationship in many fanfictions.
Their relationship could be shown as very protective. They are both fiercely protective of their baby and this brings them even closer together. They support each other in parenting decisions and in protecting their family from any threats.
Their relationship would likely be more mature. They've both been through a lot separately, so when they get back together, they'd probably be more understanding and patient with each other.
Their relationship would likely become more protective. Bruce, being Bruce Wayne, would be extremely protective of Selina and the unborn child. He might be even more vigilant in Gotham to make sure they are safe.
In many fanfictions, their relationship starts off antagonistic. Poison Ivy sees Bruce as part of the problem with the environment due to his business empire. But as the story progresses, she discovers his alter - ego Batman is actually trying to clean up Gotham in his own way. This new understanding leads to a thawing of their relationship.
Well, their relationship would go through a major transformation. The news of the pregnancy would add a new layer of depth and responsibility. Batman, who is used to a solitary and often dangerous life, would now have to think about the safety of his family. Selina, on the other hand, would have to reevaluate her life as a cat burglar. They would need to communicate more openly, share their fears and hopes for the future. There would also be a shift in their power dynamic. Batman may try to take the lead in making decisions for the safety of their family, which could cause some friction as Selina is an independent woman. But ultimately, they would need to find a balance to make their relationship work in this new situation.
In fanfiction, the relationship can be more freely explored. For example, in the official comics, their relationship often has to fit within the overarching superhero narrative. But in fanfiction, they can have more domestic moments, like cooking dinner together or just having a lazy day at home.
Their relationship could be developed uniquely by having them communicate through a series of encrypted messages. This would add an element of mystery and secrecy, typical of their characters in Gotham. As they decrypt each other's messages, they learn more about each other's thoughts and feelings.
Often, she finds out. But the circumstances and how she reacts can vary depending on the specific comic arc. Sometimes it leads to complex relationships and plot developments.
Some fanfictions develop their relationship through shared traumas. Both Batman and Harley have had difficult pasts. When they start to open up about these experiences, it creates a bond between them. For instance, Harley's past abuse at the hands of the Joker might make Batman see her in a new light, and he might offer her a chance at redemption, which then blossoms into love.
