One possible plot could be that Ursula, after seeing Ariel's determination and new - found courage, has a change of heart. She kisses Ariel as a sign of new - found respect and an unspoken truce between them. Maybe it's a moment of realization for Ursula that Ariel is more than just a mermaid who got in her way.
The plot might involve some sort of magic spell gone wrong. Ursula's spell was meant for someone else but accidentally affects Ariel. Instead of causing harm, it makes Ursula see Ariel in a different light. This new perspective leads to an unexpected kiss. It could be a kiss full of confusion at first, but then slowly turns into something more meaningful as they explore this new dynamic between them.
In a fanfiction, perhaps Ursula and Ariel are forced into a situation where they have to work together to save the underwater world. During this time, they start to understand each other better. The kiss could be a culmination of their growing bond, a moment of connection that surprises both of them. It could signify a new era of cooperation and friendship between the two characters who were once enemies.
One possible plot could be that Ursula, after some sort of magical transformation that changes her nature, falls in love with Ariel. They might face opposition from Ariel's father and the underwater kingdom at first. But as they prove their love to be true, they gradually win over the hearts of those around them and have a grand underwater wedding.
One possible plot twist could be that their kiss is part of a magical spell gone wrong. Maybe Ursula was trying to steal Ariel's voice again with a new spell, but instead, the spell backfired and made them kiss. This could lead to a strange alliance between them as they figure out how to reverse the spell.
Some fans would be excited. They love to see unexpected pairings and new interpretations of characters. It would be a fresh take on the relationship between Ursula and Ariel, and those who enjoy exploring different relationship dynamics would be all for it.
Flounder would be completely shocked. He's used to Ariel's kind - hearted nature and her love for Prince Eric. So seeing her kiss Ursula would leave him speechless and confused. He might try to talk to Ariel privately to understand what's going on.
Well, Ursula could kidnap Ariel in fanfiction because she wants to take Ariel's place. Think about it. Ariel has a loving family, a great voice, and is adored by many. Ursula, on the other hand, is often shunned. So she might think that by kidnapping Ariel and getting rid of her, she can step into Ariel's life. Maybe she wants to be the one who is loved by Prince Eric. Or perhaps she wants to be the favorite daughter of King Triton. It's all about her twisted desires for a different kind of life.
One possible plot twist could be that Ariel, while being raised by Ursula, discovers a hidden power within herself that Ursula was trying to keep dormant. Maybe it's a special kind of magic that can break Ursula's control over the sea creatures. This would lead to a power struggle between them as Ursula tries to regain control and Ariel fights for her new - found freedom and the rights of the underwater world.
A third plot could be a story where Ursula loses her powers and has to rely on Ariel for help. At first, Ursula is reluctant, but as Ariel helps her, she starts to see things from Ariel's perspective. Along the way, they face challenges like other sea creatures who don't trust Ursula, and they have to work together to prove that Ursula has changed.
Flounder could be a main character. He might be the one who first discovers Ursula's resurrection and warns Ariel. Prince Eric could also play a major role. He could lead the human side in a fight against Ursula if she decides to attack the surface world.
Flounder would definitely be there. He's Ariel's loyal friend and would be by her side to help face Ursula again.
A different way to develop their relationship could be through a magical accident. Let's say a spell backfires and Ariel and Ursula's minds are swapped. They have to live in each other's shoes for a while. Ariel experiences Ursula's loneliness and the reasons behind her actions, while Ursula gets a taste of Ariel's kind and curious nature. This could lead to a more empathetic relationship between them.
