In a fanfiction, Selina could be hesitant at first because of her independent lifestyle. However, Bruce's determination to be a great father and his love for her convinces her. They might face challenges from Gotham's villains who see the baby as a weakness or a target.
Well, it could lead to a very different dynamic in Gotham. Their relationship would become even more complex as they have to think about not only themselves but also the new life. They might have to cut back on their more dangerous activities for a while.
Some writers show it as a hesitant kiss. Given their complex relationship in the Gotham universe, they might be reluctant at first. So, the kiss could start off softly, almost like a question, and then gradually build into something more. It could also be accompanied by their internal monologues, with Bruce thinking about his responsibilities and Selina about her freedom, yet still being drawn to each other.
In some fanfictions, their kiss might be part of a dream sequence. Selina dreams of a world where she and Bruce can be together without the chaos of Gotham getting in the way. The kiss in the dream is so vivid that when she wakes up, it makes her question her true feelings for Bruce and how she wants to approach their relationship in the real world.
The idea of Gotham as a character in their relationship is also common. The city's darkness, danger, and corruption influence their relationship. For example, they might find solace in each other in the midst of Gotham's chaos. Additionally, the theme of love against all odds is prevalent. Their different backgrounds and lifestyles make their relationship difficult, but the fanfiction often shows them trying to overcome those odds to be together.
Love and attraction are very common themes. Their complex relationship, filled with passion and sometimes conflict, is often explored. Another theme is the duality of their lives in Gotham. Bruce as Batman and Selina as Catwoman have their own secrets and identities, and fanfics often play with how they deal with this while being involved with each other.
One good example could be a story where Bruce and Selina team up to solve a mystery in Gotham that involves a powerful and corrupt lemon - themed villain. Maybe the villain is using lemon - scented gas to incapacitate people and steal valuable items. Bruce uses his detective skills and Selina uses her agility and stealth to track down the villain.
Love in the face of chaos is a big theme. Gotham is a dangerous place, but Selina and Bruce's love manages to thrive. Also, the idea of two outcasts finding solace in each other. They are both different from the ordinary people in Gotham, and their relationship is a form of connection in a city that can be very isolating. And secrecy is often a theme too, as they have to keep their relationship hidden from many in Gotham.
