Yes, in many fanfictions, Damon and Elena do get back together. Fanfiction writers often explore their relationship further and give them a second chance at love, as many fans were disappointed when they didn't end up together in the original series.
Storm gets her powers back typically by undergoing some sort of spiritual or physical journey. Sometimes it's tied to ancient magic or a special encounter that unlocks her abilities again. The specific circumstances can vary depending on the comic storyline.
One success story I know is about a guy named Tom. He realized he took his girlfriend for granted. So, he started by writing her sincere letters, not just asking for forgiveness but also sharing his real feelings. He also made an effort to be part of her interests again. He joined her in volunteer work she loved. In the end, she saw his genuine change and they got back together.
She might want to manipulate Elena. Katherine is known for her devious ways, and by sharing her story, she could be trying to gain Elena's trust or sympathy for her own purposes.
Often, in fanfiction, there's a time - jump scenario. After a period of time apart, both Damon and Elena have grown and changed. Damon has become more self - less, perhaps having worked on his issues with his brother. Elena, on the other hand, has realized that her feelings for Damon were deeper than she thought. They then meet again by chance and start to rekindle their relationship. Another scenario could be that a magical or supernatural event forces them to work together. During this time, they remember all the good times they had and fall back in love.
Annabeth could show her determination by going out of her way to be in the same places as Percy. She'll be wherever he is, whether it's at his favorite spots or events he attends. And she'll always be there with a kind word or a helpful gesture, constantly reminding him of their connection. Also, she might face any danger or difficulty that comes her way while trying to get close to him again, showing that she's willing to do whatever it takes.
