take her place

Isabel stood up, facing Sarah. "Sarah, this is going too far," she said, her voice shaking with anger. "You can't keep threatening Emma like this."

Sarah just laughed. "Oh, come on, Isabel," she said, rolling her eyes. "You're so dramatic.

It's just a little harmless fun. And besides, it's not like you're any better than me."

Isabel bristled at Sarah's words. She knew they weren't true, but she also knew that Sarah was beyond reason. "Fine," she said, trying to keep her voice steady. "If you're so sure Emma won't be able to pay you back, then I'll take her place."

Sarah raised an eyebrow. "Really?" she asked, her voice dripping with sarcasm. "You're willing to do that for your little slut of a friend?"

Isabel felt her cheeks flush with anger at Sarah's words. She took a deep breath, trying to calm herself down. "Yes, I am," she said firmly. "Because Emma is my friend, and I don't like to see her get humiliated."
