King Triton would be furious. As Ariel's father, he has always seen Ursula as a threat. If he witnesses their kiss, he would likely see it as a betrayal. He might try to separate them immediately and put Ariel under some sort of restriction to keep her away from Ursula.
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.
Sebastian would probably be in a state of panic. He's always looking out for Ariel's well - being and her reputation in the ocean community. The kiss would be a scandal in his eyes. He'd probably scurry around trying to find a way to cover it up or make it seem like it was some sort of misunderstanding.
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.
Ariel might become more assertive. Since Ursula is a strong - willed character, being with her would make Ariel stand up for herself more. Ursula, on the other hand, could become more empathetic. Ariel's kind nature might soften Ursula's harsh edges.
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.
Well, obviously Ariel and Ursula are the main characters. Ariel is the curious and adventurous mermaid princess. She is known for her beautiful voice and her longing for the human world. Ursula, on the other hand, is the sea witch. She is often depicted as a villain, with her tentacles and her devious plans to take over the underwater kingdom or cause trouble for Ariel.
Harry would probably be very surprised and a bit concerned. He's always been protective of Hermione, and this sudden turn of events with Draco would make him wonder what's going on. Ron would likely be more openly shocked and perhaps a bit jealous. He has had his own complicated feelings for Hermione over the years.
She could be more assertive in a rather dark way. Ursula is a very dominant character. Ariel, growing up under her influence, might not be as gentle as in the original story. For example, when it comes to getting what she wants, she might use more forceful or underhanded methods, rather than her pure - hearted charm in the original.
Some characters might be really happy for them. For example, their close friends at Cloud 9 could have seen the chemistry between Kayla and Will all along. They would be cheering and might even plan a little celebration for the new couple. However, there could be some jealous characters too. Maybe someone who had a crush on Will or Kayla would feel a bit sour about the whole situation and try to cause some small problems between them at first.
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.
Some of the Smurfs might be really surprised at first. For example, Brainy Smurf might overthink it and worry about how it could change the dynamics in the village. But Papa Smurf, being the wise one, would probably be more accepting. He might see it as a natural progression of their relationship and encourage the other Smurfs to be supportive too.
Ash would be deeply hurt. He's a trusting person, so he'd probably feel a mix of anger and sadness. He might initially be in shock, not believing that Ursula could do such a thing.
