I also write fanfiction. Here's an example of something set in the Harry Potter universe:
Never Look Back
Molly Weasley was on her knees scrubbing at the carpet in the living room. In the kitchen, on the stove, a pot of soup was bubbling madly. As it began to boil over, she sat up and pointed her wand at it, lowering the heat enough to stop the imminent mess. Impatiently pushing her hair out of her face, she bent over the spot once more.
"Molly?" a voice behind her said quietly.
She jumped, and put her hand over her heart. "Oh, Arthur, you scared me!"
He knelt beside her and put a hand on her arm. "What are you doing, dear?"
She leaned forward and began scrubbing again. "It's so hard to get blood out of a carpet! I never should have let it dry." Her voice broke.
"Molly." Arthur caught her hand, and turned her to face him. Tears were streaming down her face.
"Oh, Arthur, I'm so scared for them! Why did I let George go like that? And he's probably not the only one that will be hurt, and what will I do if – if –" She broke off with a choked sob. "What if –"
"Sshhh." Arthur pulled her into his arms, and gently rubbed her back as she wept into his shoulder. "George was proud to help Harry, Molly."
"I know, I know. And I would never want Harry hurt, either!" Molly pulled back slightly, and looked up into her husband's eyes. "I wish this stupid war would end! I want all my babies safe."
Arthur wiped the tears from her face with his fingertips. "We all have to do what we can to stop him, dear. For Harry and our boys, that means they'll be in danger, and there's nothing we can do about it."
"I just wish –" Molly cut herself off and straightened her shoulders. "No. No point in wishing. You're right, of course, Arthur. We must do what we can do, and stop worrying at what we can't do anything about." She smiled tremulously at him. "Never look back," she whispered.
Arthur took her hand, and helped her to her feet, and they stood for a moment, wrapped in each others' arms.
