Well, imagine if Romeo didn't believe the false news of Juliet's death at all. He decides to go and rescue her from the tomb instead of killing himself. When he arrives, Paris is there, but Romeo manages to defeat him without killing him. Then, he wakes Juliet up, and together they run away to a far - off land where no one can find them, leaving their families behind to deal with the consequences of their feud.
The original ending has Cinderella marrying the prince. However, an alternate ending could be that when Cinderella is at the ball, she realizes that the life of a princess may not be for her. She leaves the ball early and returns home. There, she discovers that she has an inheritance from her mother that she can use to travel the world. She becomes an adventurer, seeing different lands and cultures, and is much happier than she could have been as a princess in a castle.
Actually, there were rumors of an alternate ending for Toy Story 4, but it was never officially confirmed or released to the public. Maybe it was scrapped during the production process.
There could be her parents. They might be the ones who taught her to be so kind and positive. Also, there could be her friends at school or in the neighborhood. They would be the ones who benefit from her sunny disposition.
Another view could be that the alternate ending is a way for fans to explore different narrative paths. It could be a way to satisfy those who felt that the original ending was too sad or left some loose ends. It might introduce new plot elements, like new characters who play a significant role in changing the outcome for Hazel and Gus. It could also be a means to explore different themes, such as the power of love in a more positive light, rather than the bittersweet way it was presented in the original.
Rather than the prince marrying another woman, in this alternate ending, he realizes that he has feelings for the Little Mermaid all along. He goes to the ocean and calls out to her. The Little Mermaid surfaces, and they confess their love for each other. With the help of a friendly sea wizard, the Little Mermaid is given legs permanently, and she and the prince live happily ever after in a castle by the sea, with the mermaids often visiting them.
One way is to re - evaluate the main character's journey. For example, if in the original ending the character achieved their goal but at a great cost, in the alternate ending, you could have them realize that the goal wasn't worth it and choose a different path. This could change the overall tone of the story from bittersweet to more positive.
