There could be a plot where the kiss is a moment of confusion for both Kara and Lena at first. But then they start to have dreams about each other that reveal their hidden desires. They then decide to explore their relationship further. Along the way, they might discover that their combined powers, not just Kara's superpowers but also Lena's intelligence and skills, can be used to create a new form of energy that could save the world. But they also have to deal with their own insecurities and the expectations of others.
One idea could be that they discover they're pregnant around the same time and support each other through the pregnancy journey. They could face challenges like dealing with work while being pregnant. For example, Kara might have to balance her superhero duties with her pregnancy, and Lena could be dealing with her business empire. They also could have a joint baby shower that brings all their friends and family together, creating a heartwarming and inclusive event.
One idea could be Kara struggling with her dark side as she is exposed to a new form of kryptonite. This kryptonite doesn't just weaken her physically but also affects her mental state, making her more aggressive and less likely to follow her usual moral code. Another plot could involve Dark Kara teaming up with an unexpected villain from another universe, creating chaos across multiple dimensions. And perhaps she starts to question her own identity, whether she is truly the hero she thought she was or if this new dark self is her real nature.
After the kiss, their relationship might develop gradually. They could start with small, secret dates. For example, flying to a remote place together where no one can find them. They'd share their deepest secrets and fears during these times.
One possible plot could be that Lena and Kara are in a dangerous situation together. As they face a powerful enemy, they realize their deep feelings for each other. In a moment of intense emotion, perhaps after one saves the other's life, they share a kiss.
In fanfiction, when Kara and Lena are married, we can expect a lot of fluff. There will be scenes of them cuddling on the couch, sharing sweet nothings. Their marriage could also mean more united front against villains. They would be each other's strength and support, making them a formidable pair.
One idea could be that they overcome some external threat together which makes them realize their love is unbreakable and they decide to get married. Maybe they fight against an anti - alien group that targets Kara, and Lena uses her intelligence and resources to protect her. This shared experience brings them closer than ever.
There might be a fanfiction where Kara's identity as Supergirl is revealed in a way that hurts her deeply, and Lena, despite their past differences, stands by her side. It could explore their complex relationship and how they deal with the fallout together.
One common theme is the slow - burn romance. Often, the fanfictions build up the relationship between Kara and Lena over time, with the kiss being a significant milestone in their journey towards love. For example, they might start as friends or reluctant allies and gradually realize their deeper feelings.
A common trope is the 'enemies to lovers' arc. At first, Lena might be a bit suspicious of Kara or vice versa, especially considering Lena's family history and Kara's secret identity. But as the story progresses, they see past their initial differences and fall in love. Also, the 'love triangle' trope can be found, although not as often. Maybe there's a third character who has feelings for either Lena or Kara, which adds some drama and tension to the relationship. And the 'found family' aspect is important too. Their relationship is not just about romantic love but also about building a family - a support system where they can be themselves and rely on each other.
One interesting storyline could be Kara adjusting to life on Earth as a young girl. Maybe she's trying to hide her powers while also making friends at school. Another could be her learning about her Kryptonian heritage in a more personal way, like finding a hidden family heirloom that gives her new insights.
