She looked at her sister shocked, not shocked that she was teasing her, but shocked her sister didn't torture her more. As soon as the confession left her lips she thought her sister would hold it over her head. Maybe Bellatrix was happier than she let Narcissa to believe and she didn't need to find entertainment in her sister's suffering at the moment or maybe she was growing out of it, but she didn't think so. She laughed relieved with her sister, "Thank you, Bella, that really means a lot to me," she said sincerely with a smile to match and she rested her hand on top of her sisters, "I hope you're happy, too."
